If its has to be odd it would most likely be 29 times instead of 28
First, how much were her songs? It's two songs each, and their separate prize was 0.99:
total prize was 2*0.99=1.98
this gets added to the membership prize:
19.99+1.98=21.97
you can also calculate this by rounding all the numbers (20+1+1) and substracting the amount you rounded (three times one cent) - the result would be the same.
Answer:
f[g(2)] = 50
Step-by-step explanation:
<u>Given functions:</u>


We are asked to determine f[g(2)], which is known as a composite function. When solving composite functions, you always work inside out.
Step 1: Find the value of g(2) by substituting 2 for x in function g(x).


Step 2: Substitute the found value into the composite function.
![\\\implies f[g(2)]= 2(4+1)^2](https://tex.z-dn.net/?f=%5C%5C%5Cimplies%20f%5Bg%282%29%5D%3D%202%284%2B1%29%5E2)
![\implies f[g(2)] = 2(5)^2 \Rightarrow 2(25) \Rightarrow \boxed{50}](https://tex.z-dn.net/?f=%5Cimplies%20f%5Bg%282%29%5D%20%3D%202%285%29%5E2%20%5CRightarrow%202%2825%29%20%5CRightarrow%20%5Cboxed%7B50%7D)
Hence, the value of the composite function f[g(2)] is 50.

Answer: c)[50,60]
Step-by-step explanation:
The Empirical rule says that , About 68% of the population lies with the one standard deviation from the mean (For normally distribution).
We are given that , The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches.
Then by Empirical rule, about 68% of the heights of students lies between one standard deviation from mean.
i.e. about 68% of the heights of students lies between 
i.e. about 68% of the heights of students lies between 
Here, 
i.e. The required interval that contains the middle 68% of the heights. = [50,60]
Hence, the correct answer is c) (50,60)
