Answer:
3x + 6 =27
Step-by-step explanation:
A. The solution is 7! First I Subtracted 6 from both sides of the equation, Then I Divided both sides of the equation by the same term. Then I got "7" from doing the following.
B. The solution is the x in the answer which is the amount of juice he poured.
"Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6 ounces left for himself"

12. ![h(x) = (x+4)^2](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%28x%2B4%29%5E2)
The parent function is
.
This graph is translated 4 units to the left of vertex of the parent function.
16. ![g(x)= -x](https://tex.z-dn.net/?f=g%28x%29%3D%20-x)
Parent function y= x
Transformation: the graph g(x) is reflected about y- axis.
18. f(x)= -2
Parent function y= 2
Transformation - Reflection about x- axis.
20. g(X) = 4x
Parent function : y= x
Transformation: Vertical stretch/ compression.
Answer: 2.5
Step-by-step explanation:
Let
be the population mean .
Then, Null hypothesis : ![H_0:\mu\leq46](https://tex.z-dn.net/?f=H_0%3A%5Cmu%5Cleq46)
Alternative hypothesis : ![H_1:\mu>46](https://tex.z-dn.net/?f=H_1%3A%5Cmu%3E46)
We assume that this is a normal distribution.
Given : Sample size : n=25 , since the sample is small (n<30) so we cannot apply z-test . Thus the test is t-test.
Sample mean : ![\overline{x}=50](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%3D50)
Population standard deviation : ![\sigma= 8](https://tex.z-dn.net/?f=%5Csigma%3D%208)
The test statistic for population mean is given by :-
![t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B%5Coverline%7Bx%7D-%5Cmu%7D%7B%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
i.e. ![t=\dfrac{50-46}{\dfrac{8}{\sqrt{25}}}=2.5](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B50-46%7D%7B%5Cdfrac%7B8%7D%7B%5Csqrt%7B25%7D%7D%7D%3D2.5)
Hence, the observed critical value = 2.5
