The maximum positive value that the correlation coefficient can have is 1.
Thus, 0.88 is pretty close, indicating a positive slope for the regression line and points lying close to that line.
You can add the numbers together so:
12.6
3.1
<u>+ 5.4
</u> 21.1
<u>
</u>Since the sum of the numbers is 21.1, it is greater than 20<u>

Answer:
$60
Step-by-step explanation:
0.80 x 75 = $60
Move all terms to the left side, and set equal to zero. Then set each factor equal to zero.
n = 5my/m+1
X+ 9 = 32
x = 32-9
so,
option c is correct.
x + 9 = 32
9 = 32 - x
so, option d is also correct.
