The correlation coefficient has to do with how well the points line up. If they are all on a line with positive slope, the correlation coefficient is 1. If that line has negative slope, the correlation coefficient is -1.

When the points are not on a line, the magnitude of the correlation coefficient is related to how "scattered" the points are. Completely random points that lie on no discernible line have a correlation coefficient of 0.

The given points lie near a line with positive slope, so the correlation coefficient is near 1. The most appropriate choice here is r = 1.

_____

The computed value of the correlation coefficient for this data is 0.968.

Branliest<br> solve the equation <br> 8.7=3.5m-2.5(5.4-6m)

ira [324]

Simplifying
8.7 = 3.5m + -2.5(5.4 + -6m)
8.7 = 3.5m + (5.4 * -2.5 + -6m * -2.5)
8.7 = 3.5m + (-13.5 + 15m)

Reorder the terms:
8.7 = -13.5 + 3.5m + 15m

Combine like terms: 3.5m + 15m = 18.5m
8.7 = -13.5 + 18.5m

Solving
8.7 = -13.5 + 18.5m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-18.5m' to each side of the equation.
8.7 + -18.5m = -13.5 + 18.5m + -18.5m

Combine like terms: 18.5m + -18.5m = 0.0
8.7 + -18.5m = -13.5 + 0.0
8.7 + -18.5m = -13.5

Add '-8.7' to each side of the equation.
8.7 + -8.7 + -18.5m = -13.5 + -8.7

Combine like terms: 8.7 + -8.7 = 0.0
0.0 + -18.5m = -13.5 + -8.7
-18.5m = -13.5 + -8.7

Combine like terms: -13.5 + -8.7 = -22.2
-18.5m = -22.2

Divide each side by '-18.5'.
m = 1.2

Simplifying
m = 1.2

Terrance wants to earn a least a B in science. His scores so far are: 91,75,68,84 is it possible for him to earn a B

MaRussiya [10]

Hi,

As of right now it is not likely for him to get a B. This is because his average is 63.6% so unless he gets better scores, he's stuck with an F.
