8.3% you need to do change divided by the original then multiply by 100
Answer:
The mean is 0.54 and the standard deviation is 0.05.
Step-by-step explanation:
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.
For a sample proportion p in a sample of size n, the mean of the sampling distribution is p and the standard deviation is .
In this problem:
So
Mean 0.54
Standard deviation .
The mean is 0.54 and the standard deviation is 0.05.
Answer:
A rhombus
and it would be centered at (2,1)
Step-by-step explanation:
Answer: 5
Steps:
5x - 2y = 30
5(8) - 2y = 30
40 - 2y = 30
-2y = 30 - 40
-2y = -10
y = -10/-2
y = 5
I would appreciate the brainliest if this answer was correct and the steps were clear and helpful! :)
