What is the purpose of a regression line? A: to connect all the points in a scatterplot B: To show the general tendency of the point in a scatterplot C: To provide a scale for the x-coordinate of the point in a scatterplot D: to provide a scale for the Y coordinate of the point in the scatterplot

D, I think

Step-by-step explanation:

B) to show the general tendency of the points in a scatterplot

Step-by-step explanation:

I took the test review on edge 2020

i think the amount would be $140.62

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
