Answer:
The answer is "2x-y=4"
Step-by-step explanation:
Given:

The Formula of Slope:

by replacing the (2,0) and (0,-4) coordinates in the above formula:

if point y intercepting in x then x=0, for this the value of x= 0 and c=-4.
Equation of the line:

apply m and c value in the above equation:

Subtract by 2x on both sides of the equation we get:

The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
