In this scatterplot the individuals are states. The variable "cig" is the number of cigarettes sold per person in the state in 1

960. The variable "lung" is the deaths from lung cancer per 100,000 people in the state in 1990. For the state of Wyoming (WY), Cig =28.04, the observed lung value is 15.92, and the predicted lung value is 21.33. Compute the residual for this point.

Answer:

e= -5.41

Step-by-step explanation:

Hello!

In linear regression, a residual value is a distance between the observed values and the regression line.

The residual value (e) is calculated as the difference between the observed value (Y) and the predicted value (^Y).

e= Y - ^Y

e= 15.92 - 21.33 = -5.41

I hope it helps!

The height in meters of a toy rocket at t seconds can be found by the
OlgaM077 [116]

Answer:   81.2

Step-by-step explanation:

h(t) = -5t² + 40t + 1.2

h(4) = -5(4)² + 40(4) + 1.2                   We plug 4 seconds as t, and solve h(4)

h(4) = -80 + 160 + 1.2

h(4) = 80 + 1.2

h(4) = 81.2

Complete the equation of the line through [1,4] and [2,2]
son4ous [18]

First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6

Explain how you can use division to simplify a complex fraction.

Reduce the final answer if needed (or reduce when you multiply).  A mixed number should be converted to an improper fraction (heavier on top) before simplifying. Change the numerator and denominator to single fractions<span> by creating a common denominator</span>
