9 X 9 X 20 X 20
Pido perdón para mí español, pero creo que este es la ecuación.
To the hundredth is 2 numbers after the decimal so since the third number is a 1 and its less than 5 it does no damage to the 9 therefore you just take away the one and you have your rounded answer, 12.79
Answer:
Distributive property
Step-by-step explanation:
Think of Distributive property being a party. the host is outside of the house (the parenthesis) and wants to greet everyone at the party. so 2x3k=6k and 2x5=10. so you replace 2(3k+5) with 6k+10
The answer is 31/3 or 10⅓
Answer:
n = 100 scores from a population with σ = 20
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, of 
n = 5 scores from a population with σ = 20
n = 5 scores from a population with σ = 80
n = 100 scores from a population with σ = 20
.
This one is the correct answer.
n = 100 scores from a population with σ = 40
.
