Answer:
Adam is the fastest runner
270 degrees this because when you count each angle it is 90 degrees then 180 degrees then 270
Okay. So to find the answer to this, let’s do 200 squared. When you find the square root of 200, you get 14.14213 and other odd numbers or 14.15 when rounded to the nearest half-tenth. Each side of the patio is about 14.15 feet.
You have to find a common denominator. In this case it will be 486/324 = x/324. Then you would have to turn the 324 around. Then it will be 486/324 X 324. Which would be 486. Therefore. X = 486. Please tell me if I am wrong. Your welcome!

The null hypothesis is 
The alternative hypothesis 
b
The 95% confidence interval is 
Step-by-step explanation:
From the question the we are told that
The population mean is 
The sample size is n = 30
The sample mean is 
The standard deviation is 
Given that the confidence level is
then the level of significance is mathematically represented as


=> 
Next we obtain the critical value of
from the normal distribution table
The value is 
Generally the margin of error is mathematically represented as

substituting values


The 95% confidence interval confidence interval is mathematically represented as

substituting values
