Answer:

Normally distributed with a mean zero.

Step-by-step explanation:

In multiple regression analysis, residuals \left ( Y-\hat{Y} \right ) should be Normally distributed with a mean zero.

               In general, multiple regression is a technique to find more about the connection between many independent variables and dependent variables. It is simple a modern approach of a simple linear regression.

Find the slope of a line parallel to this given line
dybincka [34]

bearing in mind that parallel lines have the same exact slope, then any parallel line to the one above will have the same slope as that one.

new vintage 1965 convertible requires an ol change every 400 miles and replacement of all fBuids every 13,000 mles If these serv
tekilochka [14]

Answer: There are 26000 miles that will both be due at the same time.

Step-by-step explanation:

Since we have given that

Number of miles required by new vintage = 400

Number of miles if these services have must been performed by the dealer = 13000

We need to find the number of miles from now that will both be due at the same time.

We would use "LCM of 400 and 13000":

As we know that LCM of 400 and 13000 is 26000.

So, there are 26000 miles that will both be due at the same time.

Determine the equation of the line that is parallel to y=23x+4 and passes through the point (3,7).
Licemer1 [7]

Answer:  y = 23x - 62

<u>Step-by-step explanation:</u>

Parallel lines have the same slope.

y = 23x + 4

  m=23   b=4

Input x = 3, y = 7, & m = 23 into the Point-Slope formula to find the equation or the Slope-Intercept formula to find b (you already have m).  I will choose the latter.

 y = mx + b

 7 = 23(3) + b

 7 = 69 + b

-62 = b

m = 23, b = -62  -->  y = 23x - 62
