Well,
We are given a direct proportion problem.
x varies directly as y.
When y = -5, x = 15.
Now, we are told to find x when y = 3.
We just have to recognize that the complete case is equal to the incomplete case. In other words, we set the -3 equal to the x/3.
Multiply both sides by the LCM.
LCM of -1 and 3 = 3
-9 = x
When y = 3, x = -9.
The randomly selected subject is given bone density test which are normally distributed with mean =0 and standard deviation =1. It means bone density test score is standard normal variable.
The probability that a given score is less than 2.23
P(z < 2.23)
Using z score table to find probability below z=2.23
P(z < 2.23) = 0.9871
The probability that a given score is less than 2.23 is 0.9871
Answer: 
Step-by-step explanation:
Given: It takes a robin 
hours to fly 45 miles.
Speed of robin= 
A robin can fly 10 miles per hour faster than a blue jay. It
Speed of Blue jay = Speed of robin - 10 miles per hour
= 30 miles per hour - 10 miles per hour
= 20 miles per hour
Time taken to cover 45 miles = 
Hence, it will take by a blue jay to fly that same distance.
Answer:
Par 1) 19.10 inches
Part 2) 39 days
Step-by-step explanation:
we know that
Asheville
47.71 in
124 days
Wichita
28.61 in
85 days
Part 1) About how many more inches of rain did Asheville get than Wichita?
In this part subtract the number of inches of rain in Wichita from the number of inches of rain in Asheville
so
Part 2) About how many more days did it rain in Asheville than Wichita?
n this part subtract the number of days of rain in Wichita from the number of days of rain in Asheville
so
