By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).
<h3>How to find the inverse of a function</h3>
In this question we have a <em>rational</em> function f(x) and finding its inverse consists in clearing x in terms of f(x). Prior any algebraic handling, we need to apply the following substitutions:
x · (y + 7) = - 2 · y + 2
x · y + 7 · x = - 2 · y + 2
2 · y + x · y = - 7 · x + 2
y · (2 + x) = - 7 · x + 2
By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).

Answer:
the answer is 50$ hope it helps :)
Step-by-step explanation:
Answer:. The answer is A. Probability is the numerical measure of the likelihood that an event will occur.
Step-by-step explanation:
Probability is the numerical measure of the likelihood that an event will occur. It is the ratio of the possibility of an event happening to the total number of events.
It is lesser than 100 or 1.
It is usually expressed as a fraction or decimal. The probability of an event not happening is 1 - the probability that the event happening.
This can also be expressed in terms of success or failure.
Thus, the probability of failure = 1 - probability of success

The point estimate of the population mean is ![\hat \mu = \bar X In order to calculate the critical value [tex]t_{\alpha/2}](https://tex.z-dn.net/?f=%5Chat%20%5Cmu%20%3D%20%5Cbar%20X%20%3C%2Fp%3E%3Cp%3EIn%20order%20to%20calculate%20the%20critical%20value%20%5Btex%5Dt_%7B%5Calpha%2F2%7D)
we need to find first the degrees of freedom, given by:
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
represent the sample mean
population mean (variable of interest)
s=240 represent the sample standard deviation
n=64 represent the sample size
Solution to the problem
The confidence interval for the mean is given by the following formula:

Based on the level of seniority of Mary Beth's unit, the correct conclusions on who will be terminated is:
- Unknown.
- Unknown.
<h3>Who will be terminated?</h3>
Cheryl will be terminated because both Fred and Mike have seniority over them which means that they are at least third in seniority.
However, we cannot tell who will be terminated between Mike and Sue because the relationship between them is undefined. Fred is safe from termination, however.
The rest of this question is:
1. Mike will be terminated
A)True
B)False
C)Unknown
2. Sue will be terminated
A)True
B)False
C)Unknown
