Answer:
y=x-9/3
Step-by-step explanation:
f(x)=3x+9
let f(x)=y
y=3x+9
change position of x & y
x=3y+9
rearrange:
x-9=3y
y=x-9/3

When he multiplied 8(n+20), he should have gotten 8n+160, not 8n+20.
Answer:
a.is approximately normal because of the central limit theorem.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Sample limit of 32 > 30, so the distribution is approximately normal because of the central limit theorem, and the correct answer is given by option a.
