Answer:
The coefficient of correlation=0.5
Step-by-step explanation:
We are given that
Covariance between the variable x and y=18
Variance of x=16
Variance of y=81
We have to find the coefficient of correlation
We know that
Coefficient of correlation

Using the formula



Hence, the coefficient of correlation=0.5
8n - 32 + 5m + 33 - 3
8n-32+5m+30
8n-32+30+5m ( rearranging)
8n-2+5m
answer:
5m+8n-2 or 8n+5m-2

Well, we know the formula for finding the area of a rectangle is B*H, and the formula for finding the area of a circle is πr^2
Let's find the area of a rectangle first:
25*6=150 sq in
Now the semicircles {which combined into one whole circle because they're two halves}:
The diameter is 6 inches, so the radius is 3 inches.
π(3)^2=9π
9*π=28.27 which can be rounded down to 28 sq in.
To fin the area of both, we would add them together:
150+28=178 square inches
