The residual value comes out to be 2.94 cm and height is 157.06 cm
<u>Explanation:</u>
The regression equation is calculated at the first step.
height = 105.08 plus 2.599 multiply foot length
At foot length = 20cm, height = 105.08 plus 2.599 multiply 20
= 157.06 cm
Residual = Actual minus predicted value = 160 minus 157.06
=2.94 cm
B) The residual standard deviation generally gives a sense of the goodness of fit of goodness of regression equation on our data. The magnitude tells us that how much will be predicted values from model will vary from actual values. the linear model is justified.
Answer:
The answer to your question is: y = -8/3 x - 11
Step-by-step explanation:
A (-6, 5)
B (-3, -3)
Process
1.- Find the slope of the line
Formula

Substitution

Simplifying

2.- Find the equation of the line
Formula
( y - y1) = m(x - x1)
Substitution
( y + 3) = -8/3 (x + 3)
Simplifying
y + 3 = -8/3 x - 8
y = -8/3 x - 8 - 3
y = -8/3 x - 11
Answer:
The 42 inches long fishing rod will fit in the box.
Step-by-step explanation:
The diagonal of a cuboidal box is the largest measurement inside the box.
Now, the dimensions of the box are 10 inches by 10 inches by 40 inches.
Therefore, the diagonal length of the box is
inches which is greater than 42 inches.
Hence, the 42 inches long fishing rod will fit in the box. (Answer)
Answer:
20 by 20
Step-by-step explanation:
the new dimensions have to be 12 because 12×12 =144 so you would add 8 to 12 and get 20 for each side
