Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient , 
is greater than 0.
so, ≠ - 0.9
Also, there is a deviation from absolute linearity.
So, ≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence, ≠ 0.3 .
So = 0.9

Step-by-step explanation:
Because there are 23 squares shaded out of 100.
Answer:
a = 29
b = 64
c = 87
Step-by-step explanation:
Let the angles be a (smallest), b, and c (largest).
We know that a triangle's angles must add up to 180 degrees, so we can construct the following equations.
a + b + c = 180
c = 3a
b = a +35
With some solving and substitution...
a + (a + 35) + c = 180
2a + c = 145
2a + (3a) = 145
5a = 145
a = 29
and therefore,
b = 29 + 35 = 64
c = 3(29) = 87
