The table shows the distance traveled at various times during a trip. time vs. distance traveled during a trip time (minutes), x distance traveled (miles), y 11 8 28 22 59 63 73 80 87 91 99 94 a regression calculator is used to produce a scatterplot and regression line for the data. using the equation of the line, what is the approximate distance traveled after 44 minutes? 40 miles 43 miles 47 miles 50 miles

43 miles

Step-by-step explanation:

Using a graphing calculator, first enter the x-values into the first list.  Enter the y-values into the second list.  Running the regression, we get (rounding to the nearest hundredth)

y = ax + b,

a = 1.06

b = -3.29

This gives us the equation y = 1.06x - 3.29.

Substituting 44 in place of x gives us

y = 1.06(44) - 3.29 = 43.35 ≈ 43

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
