Here is the complete question:
Brittany rents bicycles to tourists. She recorded the height (in cm) of each customer and the frame size (in cm) of the bicycle that customer rented. After plotting her results, Brittany noticed that the relationship between the two variables was fairly linear, so she used the data to calculate the following least squares regression equation for predicting bicycle frame size from the height of the customer: y'=1/3x + 1/3.
What is the residual of a customer with a height of 155 cm who rents a bike with a 51 cm frame?
The regression equation is given as:
y'=(1/3)x + (1/3)
Since the height is given as 155cm, x=155 cm
The predicted frame size,
y'=(1/3)x + (1/3)
y'=(1/3) × 155+ (1/3)
= 51 2/3 + 1/3
= 52
The observed frame size,
y=51
Residual = Observed y- predicted y
=51-52
= -1
The residual of a customer with a height of 155 cm who rents a bike with a 51 cm frame is -1.
Answer:
Michael 24
Noor 42
Step-by-step explanation:
Ratio is 4:7
The initial quatity is 4x and 7x
After giving 3 shares the quatities are
4x - 3 and 7x + 3
Set equal to the new ratio
(4x - 3) / (7x + 3) = 7 / 15
Cross multiply
15(4x - 3) = 7(7x + 3)
Distribute
60x - 45 = 49x + 21
Add 45 to both sides
60x = 49x + 66
Subtract 49x from both sides
11x = 66
Divide both sides by 11
x = 6
Therefor
4x = 4*6 = 24 <–––– Michael's initial quantity
7x = 7*6 = 42 <–––– Noor's initial quantity
