Write the multiple regression equation for miles per gallon as the response variable. Use weight and horsepower as predictor var

Naily [24]

Answer:

Step-by-step explanation:

Response Variable: Miles per gallon

Predictor Variables: Weight, Horsepower

The multiple regression equation would be: M = aW + bH + c

where M = miles per gallon

a = slope of the graph of W on M OR rate of change in M due to change in W

W = weight

b = slope of the graph of H on M OR rate of change in M due to change in H

H = horsepower

c = intercept of M on the y-axis OR constant variable

How might the car rental company use this model?

The car rental company might use the regression model to determine the following:

- Effect of weight (of car) on miles run per gallon (of premium motor spirit)

- Effect of horsepower on miles per gallon; etc.

There is a number between 100 and 115, such that if you find the sum of the cubes of the digits, subtract this sum from 99, divi

balandron [24]

114

1^3 + 1^3 + 4^3 = 1 + 1 + 64 = 66
99 - 66 = 33
33/3 = 11
1 + 1 = 2

I am not sure of the exact way to solve this....I just did it by trial and error

Denzel earned money after school delivering newspapers and doing yardwork. He put - of this month's earnings into his savings. H

Inessa05 [86]

<h3><u>Question:</u></h3>

Denzel earned money after school. He put 1/2 of this month's earnings into savings. He took the rest to spend at the amusement park. He spent 1/5 of this amount on popcorn and 3/4 of it on rides. What fraction of his earnings did he take to the park but not spend on rides or popcorn.

<h3><u>Answer:</u></h3>

$\frac{1}{40}$ fraction of money not spend in amusement park

<h3><u>Solution:</u></h3>

Let "x" be the total earnings

He put 1/2 of this month's earnings into savings

$\text{ savings} = \frac{1}{2} \text{ of } x$

$\text{ savings} = \frac{1}{2}x = \frac{x}{2}$

He took the rest to spend at the amusement park

$\text{ Remaining amount }= x - \frac{x}{2}\\\\\text{ Remaining amount } = \frac{2x - x}{2} = \frac{x}{2}$

He spent 1/5 of this amount on popcorn and 3/4 of it on rides

$\text{ Amount spend on popcorn } = \frac{1}{5} \times \frac{x}{2} = \frac{x}{10}$

$\text{ amount spend on rides } = \frac{3}{4} \times \frac{x}{2} = \frac{3x}{8}$

<em><u>So the fraction of money not spend in amusement park is:</u></em>

⇒ Remaining amount - (Amount spend on popcorn + amount spend on rides)

$\rightarrow \frac{x}{2} - (\frac{x}{10} + \frac{3x}{8})\\\\\rightarrow \frac{x}{2} - \frac{38x}{80}\\\\\rightarrow \frac{2x}{80} = \frac{x}{40}$

Thus $\frac{1}{40}$ fraction of money not spend in amusement park
