Answer: 601
Step-by-step explanation:
When the prior estimate of population proportion is not given , the formula we apply to find sample size :
, where z* = critical z-value
E=Margin of error
Given : Margin of error = 0.04
Confidence level = 95%
We know that , according to the z-table , the critical value for 95% confidence interval = z*= 1.960
Then, the required sample size : 
Hence, the required minimum sample size = 601

Answer:
49 degrees
Step-by-step explanation:
The angles of a triangle must add up to 180 degrees. So, f = 180 - 82 - 49 = 49.
A constant is a value in a formula that does not change its value.
For example, in the formula:
PV = nRT
The constant is R.
It means that regardless of the value of the other variables, R will always remain the same.
R: universal constant of gases.
Answer:
A constant is a value in a formula that does not change its value.
You would do 50+25-45. That would equal 30 points.
