klasskru [66]

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

$r=\frac{covariance(x,y)}{\sqrt{variance(x)}\times \sqrt{variance(y)}}$

Using the formula

$r=\frac{18}{\sqrt{16}\times \sqrt{81}}$

$r=\frac{18}{4\times 9}$

$r=0.5$

Hence, the coefficient of correlation=0.5

yuradex [85]

Answer:

6 miles

Step-by-step explanation:

to do this equation you must see how many times the ratio fits into 8 inches

2 fits into 8 four times so you should multiply 1.5 by 4 also

1.5 * 4 is 6

the real distance is 6 miles
