Answer:
The answer is 2.
2 since 6/4=3/2
Step-by-step explanation:
Since your relation is a direct variation then the points on your line are of the form y=kx where k is the constant of variation (also called constant of proportionality)
If y=kx then y/x=k.
So all the points in this relation since it is a direct variation will be equal to y-coordinate/x-coordinate.
So we are going to solve this proportion:
Again I put y/x from each point. They should have same ratio because this is a direct variation.
Cross multiply:
Divide boht sides by 6:
Answer:
12
Step-by-step explanation:
The expected value is , where n=148 is the sample size and
.
We calculate the z-score of 37.5 using the formula:
From the standard normal distribution table, the area to the left of 1.43 is 0.9236.
.
The expected number of people in the sample with body temperatures above 37.5 degrees is
We don't have a fractional human being, so the rule of thumb is to round up.
