Answer:
109.33
Step-by-step explanation:
given that the population has a distribution with a mean of 110 and a standard deviation of 8
Sample size n = 40
Std error of sample mean = std dev/square root of sample size
= 
From std normal distribution table we find that 30th percentile for Z is
-0.5244
Corresponding x score =
30th percentile = 109.33663
=109.33
Answer:
20
Step-by-step explanation:
This is a binomial distribution
n = 100; p = 1/5
E(x) = np = (100)(1/5) = 20
Answer:the answer is The container on the left is made of 2 centimeters squared more plastic.

First, you have to get the equation to the normal form of a line. To do this, you divide both sides by -6 to get
. The y-intercept is at -4 and your slope is 2/3. Use this to graph the equation.
