Part B
If Alex spends 20\%20% of the interest received on buying furniture for his new house, what amount did he spent on furniture?
A) The amount of interest he will earn in a year is $3,000.
B) The amount he spent on furniture is $600.
Part A: To calculate the interest Alex will earn in one year, use the formula for simple interest:
Interest = Principal × Rate × Time.
In this case, Principal = $30,000, Rate = 10% (0.10), and Time = 1 year. So,
Interest = $30,000 × 0.10 × 1 = $3,000.
Part B: Alex spends 20% of the interest on furniture. To calculate this amount, multiply the interest by 20% (0.20): $3,000 × 0.20 = $600.
Therefore, in one year, Alex will earn $3,000 in interest. He will spend $600 on furniture for his new house.

PLEASE HELP ME !!
Part A: The given definition states that an angle is two collinear rays with a common endpoint. Part B : A point is an example of an undefined term.In relation to angles, a point is crucial as it serves as the common endpoint of the two rays that form the angle.
Part A : The given definition states that an angle is two collinear rays with a common endpoint. However, this definition is incorrect as it contradicts the correct definition of an angle. In the correct definition, an angle is formed by two non-collinear rays with a common endpoint.
An example that contradicts the given definition is when you have two rays, AB and BC, with B being the common endpoint. If they were collinear, they would lie along the same straight line, and thus, no angle would be formed between them. To make the definition accurate, you would need to change it to: "An angle is formed by two non-collinear rays with a common endpoint."
Part B: An undefined term in geometry is a term that cannot be defined using other known geometric terms, but its meaning is generally understood. One example of an undefined term is a point. A point is a basic element in geometry, and it has no size, shape, or dimensions. It is merely a location in space. For instance, when discussing angle ABC, point B is the common endpoint of rays AB and BC.

We collected data from 9th and 10th. 9th grade students were 45% of the responses and 10th grade were the
rest. Of the 9th graders 31% said they did like the school lunches and 42% of the 10th graders said they did like
the school lunches. Find the probability that if we chose a student at random that they would not like the school
lunches.
Answer is 64.05% probability that if we chose a student at random
To find the probability that a randomly chosen student would not like the school lunches, we need to find the complement of the probability that they do like the school lunches.
The proportion of 9th graders in the sample is 45%, so the proportion of 10th graders is 100% - 45% = 55%.
Of the 9th graders, 31% said they liked the school lunches, so the proportion that did not like them is 100% - 31% = 69%.
Of the 10th graders, 42% said they liked the school lunches, so the proportion that did not like them is 100% - 42% = 58%.
So, the probability that a randomly chosen student would not like the school lunches is:
(0.45 * 0.69) + (0.55 * 0.58) = 0.6405 or 64.05% (rounded to two decimal places).
Therefore, there is a 64.05% probability that if we chose a student at random, they would not like the school lunches.

1. An enclosure at the zoo holds two squirrel monkeys. The floor of the enclosure is a rectangle that has an area of 36 square feet. Then the zoo gets four more squirrel monkeys. The rules say that the zoo must add 9 square feet to the floor area for each additional monkey. What must the area of the floor be for all six monkeys? Explain
To find the area of the floor needed for 6 squirrel monkeys, first calculate the additional area needed for 4 monkeys 4 x 9 = 36 square feet. Add this to the initial area of 36 square feet, to get a total area of 72 square feet. Thus, the floor area for all six monkeys should be 72 square feet.
Let's first find the area of the floor required for the additional 4 monkeys
4 additional monkeys * 9 sq ft per monkey = 36 sq ft
So, to accommodate all 6 monkeys, the total floor area required would be
36 sq ft (original area) + 36 sq ft (additional area) = 72 sq ft
Therefore, the area of the floor for all six monkeys must be 72 square feet.

The cows on a farm were producing 12.8 liters of milk per cow each day. The farmer bought 60 new cows and began using a new feed for all the cows. Now each of his cows is producing 15 liters of milk each day. How many cows are on the farm now if the farmer gets 1340 more liters of milk per day than he did before any changes were made?
There are now 260 cows on the farm.
Let's start through calculating the amount of milk produced with the aid of the original cows before any modifications were made.
If every of the unique cows was producing 12.8 liters of milk in keeping with day, and there had been "x" cows, then the entire amount of milk produced by means of the original cows could be:
12.8x liters per day
After the adjustments, the farmer has 60 more cows and all cows produce 15 liters of milk per day. So, the full amount of milk produced with the aid of all cows after the modifications would be:
15(x + 60) liters per day
we're told that the new milk production is 1340 liters more according to day than before the changes. So, we can set up an linear equation:
15(x + 60) = 12.8x + 1340
Simplifying the equation, we get:
15x + 900 = 12.8x + 1340
2.2x = 440
x = 200
therefore, there were at first 200 cows on the farm. After the changes, the full number of cows would be:
x + 60 = 200 + 60 = 260 cows
So, there are now 260 cows on the farm.

Calculate the meaning and MAD for each type of monkey.
Calculate the means-to-MAD ratio for the two types of monkeys.
What inference can be made about the weight of both types of monkeys? Explain.
Howler monkeys are heavier on average than spider monkeys (17.75 lbs vs. 11.25 lbs).
How to solveCalculate the mean:
Some of the weights divided by the number of monkeys
Calculate the MAD:
Find the absolute deviation (difference) of each weight from the mean
Calculate the average of these deviations
Mean Howler Monkey = (16+17+18+18+18+20+22+23)/8 = 142/8 = 17.75 lbs
Mean Spider Monkey = (8+10+10+11+11+12+14+14)/8 = 90/8 = 11.25 lbs
Now, we calculate the MAD for each type of monkey:
MAD Howler Monkey= 1.875 lbs
MAD Spider Monkey= 1.5625 lbs
we calculate the means-to-MAD ratio for both types of monkeys:
Howler Monkey: Mean/MAD = 17.75/1.875 = 9.466
Spider Monkey: Mean/MAD = 11.25/1.5625 = 7.2
Inference:
Howler monkeys are heavier on average than spider monkeys (17.75 lbs vs. 11.25 lbs).
The means-to-MAD ratio shows that howler monkeys have more consistent weights (9.466) compared to spider monkeys (7.2), as a higher ratio indicates less variability in weights.

In circle M with m \angle LMN= 66m∠LMN=66 and LM=19LM=19 units find area of sector LMN. Round to the nearest hundredth
We can use the formula for the area of a sector to find the area of sector $LMN$
How to find the area of a sector with central angle $\theta$ in a circle with radius $r$?The area of a sector with central angle $\theta$ in a circle with radius $r$ is given by:
$A = \frac{\theta}{360^\circ} \pi r^2$
In this case, we know that $m\angle LMN = 66^\circ$ and $LM = 19$ units, so the radius of circle M is half of the diagonal of the rectangle formed by $LM$ and $MN$. Using the Pythagorean theorem, we can find the length of $MN$:
$MN^2 = LM^2 + LN^2 = LM^2 + LM^2 = 2LM^2$
$MN = \sqrt{2} LM = \sqrt{2} \cdot 19$
So the radius of circle M is $r = \frac{1}{2}MN = \frac{1}{2}\sqrt{2} \cdot 19$
Now we can use the formula for the area of a sector to find the area of sector $LMN$:
$A = \frac{m\angle LMN}{360^\circ} \pi r^2 = \frac{66^\circ}{360^\circ} \pi \left(\frac{1}{2}\sqrt{2} \cdot 19\right)^2 \approx \boxed{90.89}$ square units (rounded to the nearest hundredth).

David's net worth: 86,329.95
To calculate David's new net worth, we need to add the increase in assets and subtract the decrease in liabilities from his current net worth.
New assets value = 62,784.24 + 2,784.89 = 65,569.13
New liabilities value = David's current net worth - his current assets value
New liabilities value = 45,765.78 - 62,784.24 = -17,018.46
Since his liabilities have decreased by 3,742.36, we need to subtract this value from the new liabilities value:
New liabilities value = -17,018.46 - 3,742.36 = -20,760.82

Using t, test the null hypothesis at the. 01 level of significance Specify the p-value for this test result. If appropriate (because the test result is statistically significant), use Cohen’s d to estimate the effect size. How might this test result be reported in the literature?
The calculated t-value of 1.100 is less than the critical t-value of 2.718, we fail to reject the null hypothesis.
To test the hypothesis that regular physical exercise improves academic achievement, we will conduct a two-sample t-test for independent samples. The null hypothesis is that there is no difference in the mean academic achievement scores between the treatment group (physical exercise) and the control group (no physical exercise).
Let's calculate the mean and standard deviation for each group:
Treatment group (physical exercise):
mean = (4 + 2.67 + 3.65 + 2.11 + 3.21 + 3.6) / 6 = 3.3833
standard deviation = 0.7589
Control group (no physical exercise):
mean = (3.75 + 2.74 + 3.42 + 1.67 + 3 + 3.25 + 2.65) / 7 = 3.0071
standard deviation = 0.7037
We can now calculate the t-statistic:
t = (3.3833 - 3.0071) / sqrt((0.7589^2 / 6) + (0.7037^2 / 7)) = 1.100
The degrees of freedom for this test are 6 + 7 - 2 = 11 (assuming equal variances).
Using a t-table or a t-distribution calculator with 11 degrees of freedom and a significance level of 0.01, we find that the critical t-value is ±2.718.
Since the calculated t-value of 1.100 is less than the critical t-value of 2.718, we fail to reject the null hypothesis. We do not have enough evidence to conclude that regular physical exercise improves academic achievement.
The p-value for this test can be calculated as the probability of getting a t-value as extreme as 1.100, assuming the null hypothesis is true. Using a t-distribution calculator with 11 degrees of freedom, we find that the p-value is 0.294 (rounded to three decimal places).
Since the test result is not statistically significant (p > 0.01), we do not need to report an effect size using Cohen's d.
This test result could be reported in the literature as follows: "A two-sample t-test for independent samples was conducted to examine the effect of regular physical exercise on academic achievement, while controlling for academic aptitude. Six pairs of college students with similar GPAs were randomly assigned to either a treatment group that attended daily exercise classes or a control group.

(a) The function rule for Big Wave Waterpark, f(x) = 2.5x + 5. where f(x) is total cost and x is number of slides ridden.
b) The function rule for Coaster City is, f(x) = 5x + 7.50, where x is the number of roller coaster ridden and f(x) is total cost.
c) The function rule for Virtual Reality Lan is, f(x) = 3x + 10, where f(x) is total cost and x is the number reality rides ridden.
(a) Let f(x) = ax +b be the function which represents the total cost of Big Wave Park where x represents the number of taken ride.
We can see that f(2) = 10; f(4) = 15 and f(6) = 20.
Therefore, 2a + b = 10 and 4a + b = 15
So, 2(2a + b) - (4a + b) = 2*10 - 15
4a + 2b - 4a - b = 20 - 15
b = 5
Now, f(6) = 20
6a + b = 20
6a + 5 = 20 [putting the value of 'b']
6a = 20 - 5 = 15
a = 15/6 = 5/2 = 2.5
Hence, the function rule for Big Wave Waterpark is, f(x) = 2.5x + 5.
(b) The function rule for Coaster city is, f(x) = 5x + 7.50, where x is the number of roller coaster ridden.
(c) Let the total cost for Virtual Reality Lan is, f(x) = cx + d, where x is the number reality rides ridden.
From the given graph we can see that, f(10) = 40; f(20) = 70; f(30) = 100.
So, 10c + d= 40 ........... (i)
20c + d = 70 ............... (ii)
Solving (i) and (ii) we get,
2(10c + d) - (20c + d) = 2*40 - 70
20c + 2d - 20c - d = 80 - 70
d = 10
So putting the value d = 10 in f(30) = 100 we get,
30c + 10 = 100
30c = 100 - 10 = 90
c = 90/30 = 3
So the function rule is, f(x) = 3x + 10.

Alyssa makes $200 for every 8 hour shift she works as a personal trainer. She graphs the amount of money she earns on the y-axis, and number of hours she works the x-axis. What is the slope of the graph?
The slope of this graph is equal to 25.
How to calculate the slope of a line?In Mathematics and Geometry, the slope of any straight line can be determined by using this mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Based on the information provided above, we can reasonably infer and logically deduce that Alyssa made $200 for every 8 hour shift she works as a personal trainer. Additionally, the amount of money Alyssa earned would be plotted on the y-axis while the number of hours she work would be plotted on the x-axis of a graph;
Slope (m) = 200/8
Slope (m) = 25.

How to solve these system of linear equations?In order to determine the solution to a system of two linear equations, we would have to evaluate and eliminate each of the variables one after the other, especially by selecting a pair of linear equations at each step and then applying the elimination method.
Given the following system of linear equations:
3y = 26 - 5x .........equation 1.
6x + 7y = 21 .........equation 2.
Rewriting in standard form, we have:
5x + 3y = 26
6x + 7y = 21
By multiplying equation 1 by 6 and dividing by 5, we have:
6x + 3.6y = 31.2 .........equation 3.
By subtracting equation 3 from equation 2, we have:
3.4y = -10.2
y = -3.
x = (26 - 3y)/5
x = (26 - 3(-3))/5

In triangle efg, ef=fg. if m < e = (4x+50), m < f = (2x+60), and m < g = (14x+30), find m < g
In the given isosceles triangle, the measure of angle G is 74 degrees.
In the given problem, we are dealing with an isosceles triangle where angle G measures 74 degrees. It is mentioned that EF and FG are congruent, indicating that triangle EFG is isosceles.
Since EFG is an isosceles triangle, we can conclude that angles E and G are congruent. Therefore, we can set the measure of angle E equal to the measure of angle G and solve for x.
By setting 4x + 50 (measure of angle E) equal to 14x + 30 (measure of angle G), we have the equation 4x + 50 = 14x + 30.
Solving for x, we find that x = 2.
Now that we have the value of x, we can substitute it into each angle measure to determine their values.
The measure of angle E (mE) is given by 4x + 50, which becomes 4(2) + 50 = 58 degrees.
The measure of angle F (mF) is given by 2x + 60, which becomes 2(2) + 60 = 64 degrees.
Finally, the measure of angle G (mG) is already known to be 74 degrees.
Therefore, the measures of the angles in the isosceles triangle are: mE = 58 degrees, mF = 64 degrees, and mG = 74 degrees.
By understanding the properties of isosceles triangles and utilizing algebraic equations, we can determine the measures of the angles in the given triangle.

What is equation?An equation is a mathematical statement that shows the equality of two expressions, often separated by an equal sign (=). The expressions on either side of the equal sign can contain variables, constants, and mathematical operations. Equations are used to solve problems, find unknown values, and represent relationships between quantities in various fields such as mathematics, physics, engineering, and economics.
Here,
The distance from Xavier's tent to the ranch is XR = (10.5z + 34) meters.
The distance from David's tent to the ranch is DR = (12.3z + 12.4) meters.
Since David and Xavier want to place their tents at equal distances from the ranch, we can set these two expressions equal to each other and solve for z:
(10.5z + 34) = (12.3z + 12.4)
Simplifying this equation, we get:
1.8z = 21.6
z = 12
Therefore, the distance from both Xavier and David's tents to the ranch is:
XR = (10.5z + 34)
= (10.5 x 12 + 34)
= 151 meters
DR = (12.3z + 12.4)
= (12.3 x 12 + 12.4)
= 159.6 meters
So both tents are 151 meters away from the ranch.

Which is an expression in terms of π that represents the area of the shaded part of ⊙R
The expression in terms of π that represents the area of the shaded part of ⊙R is 3πR²/4, obtained by subtracting the area of the smaller circle from the larger circle.
How to find the area of the shaded region in terms of π?To find the area of circle of the shaded part of ⊙R, we need to subtract the area of the smaller circle from the area of the larger circle.
The area of a circle is given by the formula A = πr², where r is the radius of the circle.
Let the radius of the larger circle be R and the radius of the smaller circle be r. Then the area of the shaded part can be expressed as:
A(shaded) = A(large circle) - A(small circle)
= πR² - πr²
We can simplify this expression further by noticing that the radius of the smaller circle is half the radius of the larger circle, so r = R/2. Substituting this into the equation gives:
A(shaded) = πR² - π(R/2)²
= πR² - πR²/4
= 3πR²/4
Therefore, the area of the shaded part of ⊙R can be expressed as 3πR²/4. This expression represents the difference in the area between the larger and smaller circles, which gives us the area of the shaded region.

When Nabhitha goes bowling, her scores are normally distributed with a mean of 115
and a standard deviation of 11. What percentage of the games that Nabhitha bowls
does she score between 93 and 142, to the nearest tenth?
The percentage of the games that Natasha scores between 93 and 142 is given as follows:
96.9%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation are given as follows:
[tex]\mu = 115, \sigma = 11[/tex]
The proportion of games with scores between 93 and 142 is the p-value of Z when X = 142 subtracted by the p-value of Z when X = 93, hence:
Z = (142 - 115)/11
Z = 2.45
Z = 2.45 has a p-value of 0.992.
Z = (93 - 115)/11
Z = -2
Z = -2 has a p-value of 0.023.
0.992 - 0.023 = 0.969, hence the percentage is of 96.9%.
