Answer:
Mean 24, standard error 0.8
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 of at least 30 can be approximated to a normal distribution with mean
and standard deviation, also called standard error 
In this problem, we have that:

What are the mean and the standard error of the sample mean?
By the Central Limit Theorem, mean 24 and standard error 
Answer:
The answer is 50
Step-by-step explanation:
You add up all the numbers and divide the numbers by how many numbers there are.
The complete pattern is: 512, 256, 128, 64, 32, 16, 8, ( and extended ) 4, 2, 1!
I do this pattern in my head literally all the time!
5x - 18 + x = 90
6x = 108
x = 18 degrees
Correct answer should be= 1.5 hours.
