Answer:  y=125+2x  or y=2x+125

Step-by-step explanation:

First, create the equation that models the situation.

The amount Anne already saves is the intial value, ory-intercept, which in this case is 125. She adds 2 to her savings everyday/ so the rate of change, or slope, is 2.

y=125+2x  or y=2x+125

plot the y intercept then plot a second point using the slope of 2 or 2/1 draw a line that connects the y intercept and the other point.

We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.

Equation:

y = 2x + 125

A sales manager collected data on annual sales for new customer accounts and the number of years of experience for a sample of 1

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

Years of experience (X) :

1

3

3

5

7

8

10

10

12

12

Annual sales (Y) :

85

105

106

122

120

113

134

The estimated regression equation obtained is :

y = b0 + b1x

b0 = 82.82967

b1 = 3.46061

ŷ = 3.46061X + 82.82967

The change in annual sales for every year of experience is given by the slope value, b1 = 3.46061 = 3.5 (1 decimal place)

The Coefficient of determination R² = 0.8477 = 0.848 ( 3 decimal place).

The Coefficient of determination gives the proportion of explained variance.

About 84.8% percent variation in annual sales can be explained by years of experience of the sales person.

Using the regression equation :

ŷ = 3.46061X + 82.82967

Years of experience, x = 8

ŷ = 3.46061(8) + 82.82967 = 110.514

111 = (to the nearest whole number)
