Write the multiple regression equation for miles per gallon as the response variable. Use weight and horsepower as predictor variables. See Step 5 in the Python script. How might the car rental company use this model
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.

f(x)=35x5
Answer:
Assuming that the question is
[tex]f(x)=\frac{3}{5x^5}[/tex]
The asnwer would be
Domain: (- ∞,0) U (0, ∞)
Range: ( - ∞,0) U (0, ∞)
Step-by-step explanation:
The domain and range of the function are:
Domain: (- ∞,0) U (0, ∞)
Range: ( - ∞,0) U (0, ∞)
Domain and Range of function
The domain are the input values for which a function exist while the range are output value for which the function exist.
Given the function:
g(x) = 35x^5
The function can exist on all real values since we will have a correspoding value of y for every value of x.

What is the slope of a line perpendicular to the line whose equation is
2x – 2y = 20.
Answer:
-1
Step-by-step explanation:
Solve for y into y=mx+b
2x-2y=20
-2y=-2x+20
y=(-2x+20)/-2
y=x-10
the slope is m, so it’s 1
A line perpendicular to that would be -1

Rick has 10 more crayons than Lori. Lori has 136 crayons. Tom has 10 fewer crayons than Rick. How many crayons does each child have?
Step-by-step explanation: Uh if Lori has 136 crayons. And rick has 10 more than her He would have 146 And tom has 10 fewer crayons than rick so he would have 136
Lori:136
Rick:146
Tom:136
And idk if u need this or not but if u want it all together it would be: 418
Hope this helps!)
Rick has 146 crayons, Lori has 136 crayons and Tom has 136 crayons'
Let the number of crayons Rick have be x
Let the number of crayons Lori has be y
Let the number of crayons tom has be z
If Rick has 10 more crayons than Lori, then;
x = 10 + y
Since Lori has 136 crayons, hence y = 136
x = 10 + 136
x = 146
If Tom has 10 fewer crayons than Rick, then;
z = x - 10
z = 146 - 10
z = 136
Hence rick has 146 crayons, Lori has 136 crayons and Tom has 136 crayons'

A club had some money to purchase new chairs. After buying 355 chairs at $199 each, there was $1,068 remaining. How much money did the club have at first? *
Answer:
$71713
Step-by-step explanation:
If each chair cost $199 then multiple 199 by 355
[tex]199*355= 70645[/tex]
If they still have 1068 then add that into the sum
[tex]70645+1068=71713[/tex]
So your answer is $71713
Answer: $71,713
Step-by-step explanation:
First you would multiply 355 by 199 to get 70,645. Next you would add the remainder of what they had, $1,068, and get the answer. hope this helps.

(__-3)(__+7)=2x^2+x-21
Answer:
(x - 3)(2x + 7) = 2x^2 + x - 21
Step-by-step explanation:
2x^2 + x - 21 = (__ - 3)(__ + 7)
The first term of the trinomial is 2x^2 which can be factored into 2x * 2.
You need to place 2x in one blank and x in the other blank.
Try it both ways. Then multiply the factors out to see which one gives you the correct middle term.
Try 2x - 3.
(2x - 3)(x + 7) = 2x^2 + 14x - 3x - 21 = 2x^2 + 11x - 21
This gives the middle term 11x, but we need the middle term to be x, so now we try x - 3.
(x - 3)(2x + 7) = 2x^2 + 7x - 6x - 21 = 2x^2 + x - 21
This gives the correct middle term, x, so this is the correct factorization.
Answer:
(x - 3)(2x + 7) = 2x^2 + x - 21

Some please help me
Answer:
48 students
Step-by-step explanation:
Represent algebra with A and physics with P
Given
Total = 50
n(A) = 39
n(P) = 16
n(Both) = 7
Required
Determine students taking Algebra or Physics
This is calculated using
n(A or P) = n(A) + n(P) - n(Both)
n(A or P) = 39 + 16 - 7
n(A or P) = 48
A total of 48 students are enrolled in either physics or algebra.
Number of students taking algebra n(A)= 39
Number of students taking physics n(B)= 16
Number of students taking both subjects n(A∩B)= 7
So, the number of students taking either physics or algebra will be the union of sets i.e. n(A∪B)
What does the union of sets represent?The union of two sets is a set containing all elements that are in A or in B (possibly both).
As we know,
n(A∪B) = n(A) + n(B) - n(A∩B)
n(A∪B) = 39+16-7
n(A∪B) = 48
Therefore, A total of 48 students are enrolled in either physics or algebra.
