Electric vehicles have become more popular in recent years due in part to advances in battery technology. How does full battery charge time relate to the driving range of the vehicle on a highway? The scatterplot and regression equation display this relationship for one specific electric vehicle from the current year. The equation of the regression line is ŷ=36.62 + 24.805x. Note that driving range varies with battery charge time, speed on the highway, and a number of other factors. Interpret the slope of the regression line.

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

7

step-by-step explanation:

the answer would be 7

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
