Suppose the correlation between two variables (z, y) in a data set is determined to be r = 0.67 What must be true about the slope, b, of the least-squares line estimated for the same set of
data?
A. O The slope will have the opposite sign as the correlation.
B. O The slope will also be a value between-1 and 1.
c. O The slope will have the same sign as the correlation.
D. O The slope b is always equal to the square of the correlation r.

0.5 meters per second

step-by-step explanation:

the average speed between 2 seconds and 8 seconds is 0.5 meters per second.

hope this ! mark brainliest!

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

s
