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.
Answer:
The cost of per kilogram of salami is = $9.1
Step-by-step explanation:
Given:
Hailey paid $13 for 
kg of sliced salami.
To find cost per kilogram of salami.
Solution:
We will apply unitary method to find per kilogram cost of salami.
If kg of salami costs = $13
Then 1 kg of salami will cost in dollars will be = 
In order to divide by mixed numbers, we will convert mixed numbers to fractions.
⇒ 
⇒ 
In order to divide by fractions we will take reciprocal of divisor and then multiply.
⇒ 
⇒ 
⇒ 
⇒ 
Thus, cost of per kilogram of salami is = $9.1
For the answer to the question above,
since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.
<span>That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value we multiply by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked. </span>
<span>You can also check this by plugging in values: </span>
<span>Assume 10 doors are knocked: </span>
<span>E(10) = 20(10)-50 = 200-50 = 150 </span>
<span>Assume 11 doors (1 more door) is knocked: </span>
<span>E(11) = 20(11)-50 = 220-50 = 170 </span>
<span>The increase from 1 door is $20.</span>

Answer is C
Explanation:
If it takes 78 days to create just one motorcycle, then:
78 days = 1 motorcycle
(78 × 2) days = 2 motorcycles
(78 × 3) days = 3 motorcycles and so on
This implies that the expression for the above statement is (78 × n) days. Also the same as 78n. Therefore, it'll take (78 × 6) days to create 6 custom motorcycles. The answer is hence 468 days.
