A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- score is 0.40.
Answer: The given z-score is false.
Explanation: We are given:
Mean, 
,
Variance, 
The z-score formula is given below:
Therefore, the z-score corresponding x=100 is 2
Therefore, the given z-score = 0.4 is false.
Answer:
19.8 or 19 4/5
Step-by-step explanation:
Step 1: Set up the expression.
Step 2: Simplify.
Therefore, the answer is 19.8 or 19 4/5.
Answer:
The slope of function A is 2 times the slope of function B.
Step-by-step explanation:
In function A, every-time the input goes up 1 the output will also go up one. In function B, every time the input goes up by 1, the output goes up by two. Therefore, the slope of function A is 1 but the slope of function B is 1/2.
1/2*2=1
8 days—> because if you 160 insurance is already added, subtract that to get your original price since that’s what is actually being counted.
So I did 760-160=600
600/75=8
