tan -1 (8/10)
Step-by-step explanation:
hope it helps :3
Answer:
x>−6
Step-by-step explanation:
-6x<36
Multiply both sides by -1. ( reverse the inequality )
(-6x) (-1) > 36 (-1)
Simplify
6x > -36
Divide both sides by 6
6x divided by 6 -36 divided by 6
Simplify
x> -6
Hope this helped
To make a dot plot, make a numbered line and add dots above the numbers of the given ages. If there are more than one of the same number, add a dot above the dot already there.

Answer:
The mean is 95 and the standard deviation is 2
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes 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:
Population:
Mean 95, Standard deviation 12
Samples of size 36:
By the Central Limit Theorem,
Mean 95
Standard deviation
