Data were recorded for a car’s fuel efficiency, in miles per gallon (mpg), and corresponding speed, in miles per hour (mph). Given the least-squares regression line, , what is the fuel efficiency for a speed of 60 mph?
3.65 mpg
33.90 mpg
36.52 mpg
38.55 mpg
The least-squares regression line equation gives the line that approximate the relationship between the variables in the fuel efficiency data
The fuel efficiency when the speed is 60 mph is approximately 38.55 mpg.
Reason:
The given least-squares regression line equation is presented as follows;
ln(Fuel Efficiency) = 1.437 + 0.541 × ln(speed)
Required:
The value of the fuel efficiency for a speed of 60 mph.
Solution:
The general form of the least-squares regression line equation is [tex]\hat y[/tex] = a + b·x
Where, in the current question, we have;
[tex]\hat y[/tex] = The predicted value = ln(Fuel Efficiency)
a = The y-intercept = 1.437
b = The slope = 0.541
x = The input value = ln(speed)
When the speed = 60 mph, we have;
ln(Fuel Efficiency) = 1.437 + 0.541 × ln(60) = 3.65204040816
Therefore;
[tex]Fuel \ Efficiency = e^{(1.437 + 0.541 \times ln(60))} \approx 38.55[/tex]
The fuel efficiency when the speed is 60 mph ≈ 38.55 miles per gallon

Answer:

Answer:
a₂₁ = 41
Step-by-step explanation:
The nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then
a₂₁ = 1 + (20 × 2) = 1 + 40 = 41

X= - 3/4Y -5. Please put this in slope intercept.
y = - 4/3 x - 20/3
Step-by-step explanation:
x = - 3/4 y - 5 Move Terms
3/4 y = - 5 - x Divide both sides
y = - 20/3 - 4/3 x Reorder the terms
y = - 4/3 x - 20/3
Hint :- The slope intercept form of the line is [tex] y = mx + c [/tex] , where m is the slope of the line and c is y intercept .
Solution:-
Given equation to us ,
[tex]\implies x = \dfrac{-3}{4}y -5 [/tex]
Multiply both sides by 4 ,
[tex]\implies 4x = -3y -20 [/tex]
Add 20 to both sides ,
[tex]\implies 4x +20 = -3y [/tex]
Divide both the sides by -3 ,
[tex]\implies \dfrac{-4}{3}x-\dfrac{20}{3}= y [/tex]
Flip the equation ,
[tex]\implies y = \dfrac{-4}{3}x-\dfrac{20}{3} [/tex]
what value of a makes the following equation true
Answer:
It's -30
Step-by-step explanation:
Combine like terms
− 8 = 2 1 0
−7 = 2 1 0
Divide both sides of the equation by the same term
− 7 = 2 1 0
-7a/-7 = 210/-7
You cancel the -7 on the left side and divide 210 by -7
and then 210/-7 is -30
