Answer:
1750
Step-by-step explanation:
well first you need to know that 100 percent from yesterday is 1400, so you now want to know what 125 percent of that is. 100 x 14 is 1400 right, so 125 x 14 is 1750.

Write the slope-intercept form of the equation of each line. Identify the slopes y-intercept
Answer:
10) m: 6
b: 5
y= 6x +5
12) m: -2
b: -1
y= -2x-1
14) m: 1
b: 0
y= x
Step-by-step explanation:
The slope-intercept form is the form y=mx+b
m is the slope. You can find it by finding two points that the line intersects, and counting the number of units between them.
Remember the slope is "rise over run", so, the difference in y over the difference in x.
b is the y-intercept. You can find it by looking at where the line crosses the y-axis.
Hope this helps you out!

Frogs: The population of a species of frog declines by 24% every year. Suppose 100 frogs are released into a pond. Which exponential model represents this population?
Answer:
p = 100(1 + 0.24)^n
Step-by-step explanation:
If this were exponential growth, we'd use the model p = 100(1 + 0.24)^n, where n is the number of years. But here we have exponential decline, which requires subtracting 0.24 in the formula instead of adding it to 1:
p = 100(1 - 0.24)^n = 100(0.76)^n

Harry fills up his Jeep with gasoline and notes that the odometer reading is miles. The next time he fills up his Jeep, he pays for gallons of gasoline. He notes his odometer reading is miles. How many miles per gallon did he get?
Complete question :
Harry fills up his Jeep with gasoline and notes that the odometer reading is 23,568.7 miles. The next time he fills up his Jeep, he pays for 12.6 gallons of gasoline. He notes his odometer reading is 23,706.3 miles. How many miles per gallon did he get?
Answer:
10.9 miles per gallon
Step-by-step explanation:
Given that :
Odometer reading when filled up with gasoline = 23,568.7 miles
Odometer reading with 12.6 gallons of gasoline = 23,706.3 miles
Miles per gallon gotten :
(Current Odometer reading - reading when filled up) / gallon of gasoline
(23706.3 - 23568.7) / 12.6
= 10.920634
= 10.9 miles per gallon

Make both fractions have equal denominators:
2 x3 -----> 6/15
5 x3
6/15 + 5/15 = 11/15 ---> 15/15 - 11/15 = 4/15

Consider the line y=5x -3 Find the equation of the line that is patellar to this line and passes through the point (-8, -3) Consider the line y=5x -3
Answer:
The equation of the line that is parallel to given line and passes through the point (-8, -3) is: [tex]y = 5x+37[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]y=5x-3[/tex]
The general form of equation of line in slope-intercept form is written as:
[tex]y = mx+b[/tex]
Here m(co-efficient of x) is the slope of the line and b is the y-intercept.
Comparing the given equation with the general form we get
m = 5
Two parallel lines have same slope so the slope of any line parallel to given line will also be 5.
Let m1 be the slope of required line parallel to y=5x-3
Then m1=5
Putting in general form
[tex]y = m_1x+b[/tex]
[tex]y=5x+b[/tex]
To find the value of b(y-intercept) the given point has to be put in the equation from which the line passes.
The point is (-8,-3)
[tex]-3 = 5(-8)+b\\-3 = -40+b\\b = -3+40\\b = 37[/tex]
Putting the value of b and m1, we get
[tex]y = 5x+37[/tex]
Hence,
The equation of the line that is parallel to given line and passes through the point (-8, -3) is: [tex]y = 5x+37[/tex]

If the surface area of a cylinder is 288 picm2 with radius of 8 cm, what is the volume of the cylinder? (in terms of m)
A)
320pi cm3
B)
640pi cm3
9.
720pi cm?
D)
980pi cm3
help me pls hurry thanku
Answer: The volume of the cylinder is 640π cm³
Step-by-step explanation:
The formula of the surface area of a cylinder is SA = 2πrh + 2πr², where r is the radius of its base and h is its height
The formula of the volume of a cylinder is V = πr²h
Let us use the formula of the surface area to find the height of the cylinder, then use the formula of the volume to find its volume
∵ The surface area of a cylinder is 288π cm²
∵ Its radius is 8 cm
∵ SA = 2πrh + 2πr²
- Substitute the SA by 288π and r by 8 in the formula
∴ 288π = 2π(8)h + 2π(8)²
∴ 288π = 16πh + 128π
- Subtract 128π from both sides
∴ 160π = 16πh
- Divide both sides by 16π
∴ 10 = h
∴ The height of the cylinder is 10 cm
Now let us find the volume of the cylinder
∵ V = πr²h
- Substitute r by 8 and h by 10
∴ V = π(8)²(10)
∴ V = π(64)(10)
∴ V = 640π
The volume of the cylinder is 640π cm³
6c = 7c − 7
with work shown
Answer:
c = 7
Step-by-step explanation:
6c = 7c - 7
Subtract 6c to both sides
0 = c - 7
Add 7 to both sides
c = 7
Answer:
c = 7
Step-by-step explanation:
Step 1: Subtract 7c from both sides.
6c − 7c = 7c − 7 − 7c
−c = −7
Step 2: Divide both sides by -1.
-c/-1 = -7/-1
c = 7

Answer the following questions about confidence intervals.
(a) What happens to a confidence interval as sample sizeincreases, assuming everything else stays the same?
The width of the interval decreases, since the standard error decreases.The center of the interval decreases, since the standard error increases. The center of the intervalincreases, since the standard error decreases.The width of the interval increases, since the standard error increases.
(b) If we want to use a larger confidence level when creating a confidence interval for a population mean, which of the following happens to our confidence interval?
The interval gets wider, since the standard error decreases.The interval gets narrower, since the t-value required to capture a larger proportion of the sampling distribution of the sample mean gets smaller. The interval gets narrower, since the standard error decreases.The interval gets wider, since the t-value required to capture a larger proportion of the sampling distribution of the sample mean gets larger.
(c) What does the margin of error in a confidence interval for a population mean describe?
It describes the difference between the sample mean and the population mean due to calculation errors by the researchers. It describes the difference between the sample mean and the population mean. Due to the random sampling method, different sample means will be different. It describes the difference between the sample mean and the population mean, due to taking non-random samples involving voluntary response or convenience sampling.It describes how often researchers make a mistake due to response bias or non-response bias.
(d) Why do we use a z-score from a normal distribution in constructing large-sample confidence intervals for a proportion?
For large random samples the data distribution is approximately normal.For any n we use the t-distribution to get a confidenceinterval, and for large n the t-distribution looks like the standard normal distribution. For large random samples the sampling distribution of the sample proportion is approximately normal.The population distribution is normal for large samples.
(e) True or false: The confidence interval for a mean with a random sample of size n = 2000 is invalid if the population distribution is bimodal.
TrueFalse
Answer:
the options are not numbered so I have added each of the correct answers under their corresponding question number. the answers in bold letters are right options from the question.
Step-by-step explanation:
a.)
the width of the interval decreases, since the standard error decreases. this is the answer to this question. this happens to a confidence interval as the sample size gets increased. that is if every other thing remains the same.
b.
the answer to this question is that the interval gets wider since the t value required to Capture a larger proportion of the sampling distribution of the sample mean gets larger. so the last option is the answer to the question.
c.
the margin of error shows the degree of random sampling error that is in the result of a survey. the correct answer to this question is this:
in a confidence interval for a population mean, the margin of error describes the difference between the sample mean and the population mean. Due to the random sampling method, different sample means will be different.
d.
regarding this question, we use a z score because:
For large random samples the sampling distribution of the sample proportion is approximately normal.
e.
the answer to this is false.

What is algebraic equation ?
In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations. For example, 3x² − 2xy + c is an algebraic expression.
There are various method through which we can solve or define the algebraic expression. One definition I have mentioned earlier..
To solve this equation
if a = 1, the equation x^2 + x = can be completed as follows :
x^2 + x = x ( x + 1 )
Therefore, the final answer is : x^2 + x = x ( x + 1 )
