Answer with explanation:</h2>
When there is a linear relationship is observed between the variables, we use linear regression predict the relationship between them.
Also, we predict the values for dependent variable by modelling a linear model that best fits the data by drawing a line Y=a+bX, where X is the explanatory variable and Y is the dependent variable.
In other words: The line of best fit is a line through a scatter plot of data points that best describes the relationship between them.
That's why the regression line referred to as the line of best fit.
-3 =-2x - 7
Add 7 to both sides
4=-2x
Divide by -2
-2 = x

Answer:
84 in
Step-by-step explanation:
The Pythagorean theorem is used to find the length 'b'.
b^2 +12^2 = 37^2
b = √(37^2 -12^2) = √1225 = 35
Then the perimeter is the sum of side lengths:
P = a + b + c = 12 + 35 + 37
P = 84 . . . inches
Answer:
Step-by-step explanation:
Here X no of defective batteries is binomial with p = 1% = 0.01
q = 1-p=0.99
(Because each battery is independent and there are only two outcomes)
Prob that shipment is accepted is for n =36, 
=P(x=0,1,2)
= 
= 0.9944
