The image graph for this question is missing, so i have attached it.
Answer:
The greatest amount of Rainfall is 16 times the least amount of Rainfall.
Step-by-step explanation:
From the image, we can see the average monthly Rainfall and the frequency of each size in inches.
The largest is 2 inches while the smallest is ⅛ inches.
We are basically required to find the number that will be multiplied by the least amount of Rainfall to get the greatest amount.
Thus, we will just divide the greatest amount of Rainfall be the least.
This is; 2 ÷ ⅛ = 16
Graph best represents the equation y=-2x-2
Answer-D
Answer: 0.8461
Step-by-step explanation:
Given : 
Let x be the random variable that represents the cost for the hospital emergency room visit.
We assume that cost for the hospital emergency room visit is normally distributed .
z-score for x=1000 ,
Using z-value table , we have
P-value =P(x>1000)=P(z>-1.02)=1-P(z≤ -1.02)=1-0.1538642
=0.8461358≈0.8461 [Rounded nearest 4 decimal places]
Hence, the probability that the cost will be more than $1000 = 0.8461
K=4 I think is the answer.
