How do you Divide 88 by1/4+20=?
Artyom0805 [142]

88 divided by 1/4 can be placed like this: 88/1 divided by 1/4, which should lead to an answer of 22/1 or 22. Then you add 20, so 22 plus 20 would equal 42. 42 is the correct answer.

A linear regression is done on data the line of best fit is y= 1.25x-6.25. What is the residual for the point (1,1)?
Damm [24]

Answer:

6

Step-by-step explanation:

Find the predicted y value when x=1:

\hat{y}=1.25x-6.25\\\hat{y}=1.25(1)-6.25\\\hat{y}=1.25-6.25\\\hat{y}=-5

Find the residual:

\text{Residual}=\text{Actual Value}-\text{Predicted Value}\\\text{Residual}=y-\hat{y}\\\text{Residual}=1-(-5)\\\text{Residual}=1+5\\\text{Residual}=6

Because our residual is positive, this is an indicator that our predicted y value is too low.

Bob's motorboat rents a motorboat for $52 an hour plus an extra $6. If Jenna rents a motorboat for 6 hours how much will it cost her?

Equation: 52x+6=y

X=6 so 52•6+6= 318

So she would pay $318
