The answer is 120.............
Answer:
B. The absolute value parent function
Step-by-step explanation:
![f(x)=|x|](https://tex.z-dn.net/?f=f%28x%29%3D%7Cx%7C)
Referred to as absolute value, the value inside the bars is measured in terms of its distance from 0. Therefore:
![|0|=0\\|3|=3\\|-3|=3](https://tex.z-dn.net/?f=%7C0%7C%3D0%5C%5C%7C3%7C%3D3%5C%5C%7C-3%7C%3D3)
In essence, a negative value within the bars becomes positive, while a positive value remains positive.
It is a good idea to check to see if your answer is reasonable because a. if your answer is reasonable, you have probably done the problem correctly.
To find the standard error, divide the standard deviation by the square root of the sample size
standard deviation = 7.5
sample size = 25......sqrt 25 = 5
standard error = 7.5 / 5 = 1.5 <==
