The polygon is a hexagon with 6 sides. The sum of the interior angles= 360. Divide 360 by 6 to get 60. The measure of angle x=60. I hope this helps you!
Answer:
Decreasing the sample size decreases the width of the confidence interval.
Step-by-step explanation:
-Let s be the sample standard deviation and 
be the sample mean.
#We calculate the 95% confidence interval for the sample size 100 as below:
#we then calculate the confidence interval of sample size =50 and of similar mean and standard deviation:
#Notice that the smaller sample(n=50) has a narrower confidence interval.
Hence, decreasing the sample size decreases the width of the confidence interval.

Answer:
a = 6
Step-by-step explanation:
Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is
P(2) = 2² - 5(2) + a = 0 , so
4 - 10 + a = 0
- 6 + a = 0 ( add 6 to both sides )
a = 6
