Actually variation is simply equivalent to the square of
the correlation coefficient r. So we can say that:
variation = r^2
So given an r value of 0.743, so the variation is:
variation = 0.743^2
variation = 0.552
Answer:
55.2%
Answer:
y = -x + 8
Step-by-step explanation:
First, plug in the slope.
y = mx + b
y = -1x + b
y = -x + b
Then, plug in the point.
7 = -(1) + b
7 = -1 + b
8 = b
Hi!
Let's separate this shape into 3 smaller shapes. (see image)
Let's start with the green shape. The base is 5, and the height is 4.
5 x 4 = 20
Now the blue shape. The base is (15 - 5) 10, and the height is (3 + 4) 7.
10 x 7 = 70
Now finally, the red shape. The base is (15 - 12) 3, and the height is (11 - 4) 7.
7 x 3 x 0.5 = 10.5
Now add all of the areas together. 20 + 70 + 10.5 = 100.5
The answer is
100.5Hope this helps! :)
