Answer:
A = 28 units²
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
here b = FG = 8 and h = FE = 7 , then
A = [tex]\frac{1}{2}[/tex] × 8 × 7 = 4 × 7 = 28 units²
Lines lll, mmm, and nnn are parallel to each other and ppp is a transversal.
Also, 2\angle{x}=3\angle{y}2∠x=3∠y2, angle, x, equals, 3, angle, y
The measure of angle x is: x = (3/5)(180 - z) = (3/5)(180 - 90) = 36 degrees
And the measure of angle y is:y = (2/5)(180 - z) = (2/5)(180 - 90) = 24 degrees
Since lines lll, mmm, and nnn are parallel to each other and ppp is a transversal, we can use the angle properties of parallel lines to find the relationship between angle x and angle y.
From the given information, we have: 2x = 3y
Simplifying this equation, we get: x = (3/2)y
Now, we can use this relationship to find the measures of angles x and y in terms of a common variable. Let's use z as the common variable.
x + y + z = 180 (angles on a straight line)
Substituting x = (3/2)y, we get: (3/2)y + y + z = 180
Simplifying this equation, we get: (5/2)y + z = 180
Now, we can express y in terms of z:
(5/2)y = 180 - z
y = (2/5)(180 - z)
Similarly, we can express x in terms of z:
x = (3/2)y = (3/2)(2/5)(180 - z) = (3/5)(180 - z)
Now, we can use the relationship between angle x and angle y to find the measure of angle x in terms of z: 2x = 3y
2[(3/5)(180 - z)] = 3[(2/5)(180 - z)]
Simplifying this equation, we get: (6/5)z = 108
z = (5/6)(108) = 90

What is the value of 6x*2 +17 when x=8
Answer:
113 or 401: see below for explanation
Step-by-step explanation:
x = 8
The way you wrote it with the " * " symbol, it means the multiplication of 6x and 2. This is what I did in the line below.
6x × 2 + 17 = 6 × 8 × 2 + 17 = 48 × 2 + 17 = 113
If by " * " you actually meant an exponent, such as 6x², then here is the calculation using 2 as an exponent. For exponent, we normally use ^, such as 6x^2 to mean 6x².
6x² + 17 = 6 × 8² + 17 = 6 × 64 + 17 = 384 + 17 = 401

the line is parallel to the graph of 2x-3y=7 and contains the point (-3, -3)
The equation of the line that is parallel to the graph of 2x-3y=7 and contains the point (-3, -3) is expressed as: y = (2/3)x - 1.
What is the Equation of Parallel Lines?To find the equation of a line that is parallel to the graph of 2x - 3y = 7, we need to determine the slope of the given line. We can rewrite the equation in slope-intercept form:
2x - 3y = 7
-3y = -2x + 7
y = (2/3)x - 7/3
This implies that the slope of this line is m = 2/3.
Thus, the equation of the line we are to find will take the following form:
y = (2/3)x + b
where b is the y-intercept of the line.
To find the y-intercept (b), substitute (x, y) = (-3, -3) and m = 2/3 into y = mx + b:
-3 = (2/3)(-3) + b
-3 = -2 + b
b = -1

The area of the object is 40 square centimeters
The correct answer is an option (B)
We know that the formula for the area of trapezoid is,
A = ((a + b)/2) × h
where a and b are the two parallel bases
h is the height of the trapezoid
From the attached figure, first we determine the length of the two parallel bases.
Let us assume that 'a' represents the length of the upper base and 'b' represents the length of the bottom side of the trapezoid
We can observe that a = 2x
so the length of a = 6 centimeters
And b = 2z
So, the length of b = 2(5)
= 10 cm
Here, the height h of the trapezoid is given by y = 5 cm
Using above formula for the area of trapezoid, the area of the object would be,
A = ((a + b)/2) × h
A = ((6 + 10)/2) × 5
A = (16/2) × 5
A = 40 cm²

350 divided by 80 is equal to 4 with a remainder of 30, or in decimal form, it is approximately 4.375.
We have,
To divide 350 by 80, we can perform the division operation as follows:
- First, we check how many times 80 can be divided into 350. We start with the largest multiple of 80 which is less than or equal to 350, which is 4.
80 x 4 = 320
- We subtract 320 from 350 to find the remainder:
350 - 320 = 30
- Since the remainder is not zero,
We can continue dividing. We bring down the next digit of 350, which is 0.
- Now, we have 300 as the new dividend.
We ask ourselves how many times 80 can be divided into 300.
80 x 3 = 240
- Subtracting 240 from 300 gives us the new remainder:
300 - 240 = 60
- Again, the remainder is not zero, so we continue.
- We bring down the last digit of 350, which is 0, and our new dividend becomes 600.
- We ask ourselves how many times 80 can be divided into 600.
80 x 7 = 560
- Subtracting 560 from 600 gives us the new remainder:
600 - 560 = 40
- The remainder is still not zero, so we continue.
- Finally, we bring down the last digit of 350, which is 0.
Our new dividend is 400.
We ask ourselves how many times 80 can be divided into 400.
80 x 5 = 400
- Subtracting 400 from 400 gives us zero as the remainder.
Since the remainder is now zero, we can stop dividing.
Therefore,
350 divided by 80 is equal to 4 with a remainder of 30, or in decimal form, it is approximately 4.375.
In summary, 350 divided by 80 equals 4 with a remainder of 30, or 4.375.

A jar contains 11 red marbles, 12 blue marbles, and 6 white marbles. Four marbles from this jar are selected, with each marble being replaced after each selection. What is the standard deviation of X, the number of draws until the first red marble? 0. 4852 0. 9704 2. 0770 1. 5172
The standard deviation of X to be approximately 0.4852. The correct answer is option (A).
To calculate the standard deviation of X, we need to first calculate the probability of drawing a red marble on the first draw, which is 11/29. The probability of not drawing a red marble on the first draw is 18/29. The probability of drawing a red marble on the second draw, given that we did not draw a red marble on the first draw, is 11/29. Using the formula for the geometric distribution, which models the number of trials until the first success, we can calculate the expected value of X, which is 1/p, where p is the probability of success (11/29 in this case).
Therefore, the expected value of X is 29/11. To calculate the standard deviation of X, we use the formula sqrt(q/p^2), where q is the probability of failure (18/29) and p is the probability of success (11/29). Plugging in these values, we get the standard deviation of X to be approximately 0.4852. Therefore, the correct answer is option A, 0.4852.

the following list shows the number of goals scored by a soccer team in each of 9 games. 0 0 1 1 1 3 3 4 5 how does the median number of goals scored compare with the mean number of goals scored? responses
The median number of goals scored is 1, and the mean number of goals scored is 2. The median is less than the mean, indicating a right-skewed distribution.
To find the median, we need to first put the numbers in order
0, 0, 1, 1, 1, 3, 3, 4, 5
There are an odd number of values, so the median is the middle value, which is 1.
To find the mean, we add up all the values and divide by the number of values
(0 + 0 + 1 + 1 + 1 + 3 + 3 + 4 + 5) / 9 = 2
So the mean number of goals scored is 2.
Since the median (1) is less than the mean (2), we can say that the distribution is skewed to the right. This is because the high value of 5 pulls the mean up, while the median is not affected as much by outliers.

Exponents, functions, and other mathematical symbols may also be included.
In mathematical equations and formulas, expressions are used to represent numbers, calculations, and relationships.
The length of the rectangular patio is given by the expression:
length = (t^2 + 19t + 84) / (4t - 4)
The width of the rectangular patio is given by the expression:
width = (2t - 2) / (t² + 9t + 14)
The area of the rectangular patio is given by the product of its length and width:
area = length x width
By substituting, we get:
area = [(t² + 19t + 84) / (4t - 4)] x [(2t - 2) / (t² + 9t + 14)]

The P-value is the probability of obtaining a test statistic as extreme or more extreme than the observed data, assuming that the null hypothesis is true. In this case, the P-value is 0.06, which means that if the true proportion of good serves for Devon is actually 72%, there is a 6% chance of observing a sample of 50 serves with 42 or more good serves.

please help me
To prove that the right triangles are congruent, we need to show that they have three pairs of congruent parts (sides or angles).
Let's say that the given congruent parts are the hypotenuses and one leg of each triangle. To prove congruence, we can add one more pair of congruent parts, such as the other leg.
By the Side-Angle-Side (SAS) congruence theorem, if two triangles have two pairs of congruent sides and the included angle is also congruent, then the triangles are congruent. In this case, we have two pairs of congruent sides (the hypotenuses and one leg) and the included angle (the right angle) is congruent by definition.
Therefore, we can conclude that the two right triangles are congruent by SAS.

multiply the polynomials
To multiply the polynomials (1-2t)(5t+t^2), we can use the distributive property and multiply each term in the first polynomial by each term in the second polynomial:
(1-2t)(5t+t^2) = 1(5t+t^2) - 2t(5t+t^2)
Multiplying the first term by each term in the second polynomial, we get:
5t + t^2
Multiplying the second term by each term in the second polynomial, we get:
-10t^2 - 2t^3
Combining like terms, we get:
-2t^3 - 10t^2 + 5t
Therefore, the answer is D. -2t^3 - 9t^2 + 5t.
Compute the number of 12 letter combination of the 26 letters in alphabet.
key answer:
9,675,700
To compute the number of 12 letter combinations of the 26 letters in the alphabet, we can use the formula for combinations, which is:
nCr = n! / r!(n-r)!
where n is the total number of items (26 letters in this case), r is the number of items to choose (12 letters in this case), and ! means factorial (the product of all positive integers up to that number).
Using this formula, we can plug in the numbers:
26C12 = 26! / 12!(26-12)!
= (26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15) / (12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)
= 9,675,700
Therefore, there are 9,675,700 possible 12 letter combinations of the 26 letters in the alphabet.

Suppose that prices of a gallon of milk at various stores in one town have a mean of $3.75 with a standard deviation of $0.09. using chebyshev's theorem, what is the minimum percentage of stores that sell a gallon of milk for between $3.57 and $3.93? round your answer to one decimal place.
68% of the stores will sell a gallon of milk for between $3.57 and $3.93 with one standard deviation of the mean.
Mean = $3.75
Standard deviation = $0.09.
Selling variations = $3.57 to $3.93.
Chebyshev's theorem states that if k is a positive number, then, in any data at least [tex](1 - 1/k^2)[/tex] of the data will fall in K standard deviations from the mean data.
For normal distributions, 68% of the values will fall within one standard deviation of the mean.
For non-normal deviations, 75% of values will fall within 2 standard deviations of the mean.
Here we need to find the Upper limit and lower limit of the data.
$3.75 - $0.09 = $3.66
$3.75 + $0.09 = $3.84
The price range will be between $3.66 and $3.84.
To calculate the minimum percentage of stores using Chebyshev's theorem
minimum percentage = [tex]1 - 1/k^2[/tex]
minimum percentage = [tex]1 - 1/(1^2)[/tex]
minimum percentage = 0
Here, 0% of stores will fall with only one standard deviation from the Mean.
Therefore, we can conclude that 68% of the stores will sell a gallon of milk for between $3.57 and $3.93.
