Answer:
The inverse function is [tex]g(x) = \frac{x - 2300}{170}[/tex]
The value of g(x) represents the number of applicants to the freshman class based on the number of years since 2010.
Step-by-step explanation:
Number of applicants in x years after 2010:
Is given by the following function:
[tex]f(x) = 2300 + 170x[/tex]
Inverse function:
We exchange the values of y = f(x) and x in the original function, and then find y. So
[tex]x = 2300 + 170y[/tex]
[tex]170y = x - 2300[/tex]
[tex]y = \frac{x - 2300}{170}[/tex]
[tex]g(x) = \frac{x - 2300}{170}[/tex]
The inverse function is [tex]g(x) = \frac{x - 2300}{170}[/tex]
Meaning of g:
f(x): Number of students in x years:
g(x): Inverse of f(x), is the number of years it takes for there to be x applicants, so the answer is:
The value of g(x) represents the number of applicants to the freshman class based on the number of years since 2010.

If you charged $10.25 an hour for your assistance, about how many hours would you
need to work to earn $8,425? Show your work. (
9514 1404 393
Answer:
about 822 hours
Step-by-step explanation:
If h is the number of hours for which you are paid $10.25 per hour, then the number you need is ...
8425 = 10.25h
Divide by the coefficient of h:
8425/10.25 = 10.25h/10.25
821.95121...(5-digit repeating decimal)
You need to work about 822 hours to earn $8425.
_____
Your pay for 822 hours will be $8425.50. If taxes are deducted, you need to work a while longer.

In the past year Christine watched 24 movies that she thought were very good. She watched 60 movies over the whole year. of the movies she watched, what
percentage did she rate as very good?
Answer:
40%
Step-by-step explanation:
She thought that 24 movies out of 60 were very good. Put the smaller number over the larger number to create a fraction:
Then convert 24/60 to a proper fraction:
24/60 = 2/5
Then, convert that to percent:
2/5 = 40%

Assuming that a person going to community college can't afford to go to a four-year college is an example of a) a generalization. b) discrimination. O c) a stereotype. O d) tolerance.
Answer:
a) generalization
Step-by-step explanation:
The statement is an example of a generalization. This is because the statement is assumming that all individuals who go to community college are poor. Therefore, this is why they cannot go to a four-year college, and instead go to a community college which is far cheaper. This assumption is being applied to all individuals who attend community college, without any further or more-specific information about each individual, therefore generalizing the entire situation.

g Two different factories named A and B both produce an automobile part. If a part came from A, the probability that the part is defective is .04. If the part came from B, the probability that it is defective is .05. In a sample of 180 parts, 100 came from A and 80 came from B. (a) What is the probability that a part chosen at random (from the sample) was defective
Answer:
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Step-by-step explanation:
Probability of a defective part:
0.04 of [tex]\frac{100}{180}[/tex], that is, coming from A.
0.05 of [tex]\frac{80}{180}[/tex], that is, coming from B. So
[tex]p = 0.04\frac{100}{180} + 0.05\frac{80}{180} = \frac{0.04*100 + 0.05*80}{180} = 0.0444[/tex]
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Which confidence level would produce the widest interval when estimating the mean of a population based on the mean and standard deviation of a sample of that population? A. 60% B. 70% C. 80% D. 90%
Answer:
D. 90%
Step-by-step explanation:
it is within the 90th percentile
The confidence level of D. 90% would produce the widest interval when estimating the mean of a population from the mean and standard deviation of a sample of that population.
What is Confidence Interval?Confidence interval in statistics is defined as the certain range of values that you estimate for the unknown parameter lies within.
From the definition of the confidence interval itself, it is clear that the level with the widest interval will be the highest confidence level.
So if you need a wider interval for estimating the mean of a population from the mean and standard deviation, you need to take higher confidence level.
Here the options are 60%, 70%, 80% and 90%.
Here, the highest level is 90% which is the highest among the given levels.
Hence the confidence level is option D. 90%.

Determine if the outside temperature is a function of the time of day or if the time of day is a function of temperature and explain why or why not.
Answer:
Step-by-step explanation:
Temperature is a function of the time of day. There can be only one temperature at any particular time.
In contrast, a particular temperature can occur more than one time in a day, so time is not a function of temperature.

The perimeter of Tamara's suitcase is 8x - 3 and the perimeter of Anna's suitcase is
3x + 2. Write an algebraic expression that represents
the difference between the perimeter of Tamara's suitcase
and the perimeter of Anna's suitcase?
Answer:
perimeter: 2
Step-by-step explanation:
8x-3 = 6x
8x – 6x = 3
2x = 3
x = 3/2
The required algebraic expression that represents the difference between the perimeter of Tamara's suitcase and the perimeter of Anna's suitcase is 5x - 5.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
The difference between the perimeter of Tamara's suitcase and Anna's suitcase can be found by subtracting the expression for the perimeter of Anna's suitcase from the expression for the perimeter of Tamara's suitcase:
(8x - 3) - (3x + 2)
Simplifying the expression by removing the parentheses and combining like terms, we get:
8x - 3 - 3x - 2
= 5x - 5
Therefore, the algebraic expression that represents the difference between the perimeter of Tamara's suitcase and the perimeter of Anna's suitcase is 5x - 5.

Volunteering: The General Social Survey asked 1309 people whether they performed any volunteer work during the past year. A total of 518 people said they did. Part: 0 / 30 of 3 Parts Complete Part 1 of 3 (a) Find a point estimate for the population proportion of people who performed volunteer work in the past year. Round the answer to at least three decimal places. The point estimate for the proportion of people who performed volunteer work in the past year is .
Answer:
The point estimate for the population proportion of people who performed volunteer work in the past year is 0.396.
Step-by-step explanation:
Point estimate of a proportion:
Proportion is the number of desired outcomes divided by the number of total outcomes.
518 out of 1309 people performed volunteer work:
This means that:
[tex]p = \frac{518}{1309} = 0.396[/tex]
The point estimate for the population proportion of people who performed volunteer work in the past year is 0.396.
The midpoint of AB is (1.2). The coordinates of A are (-3, 6) Find the coordinates of B.
Answer: coordinates of B are (5,-2)
Step-by-step explanation:
let B be (x2,y2)
x1 = -3 y1 = 6
x = 1
y = 2
so
x = (x2 + x1)/2
1 = (x2+(-3))/2
or, 2 = x2 - 3
so, x2 = 5
now
y = (y2+y1)/2
or, 2 = (y2 + 6)/2
or, 4 = y2 + 6
so, y2 = -2
