F(x)=1/3-1/21x
0=1/3-1/21x multiply both side by 21
0=7-x
X=7
Answer:
8/19
Step-by-step explanation:
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Get the given data values
STEP 2: Write the formula for calculating the coefficient
STEP 3
: Calculate the correlation coefficient
Using the calculator,
Hence, the value of r is 0.791
Since it's mid segment, WZ and ZX are equal
2x + 10 = 5x + 4
Solve for x
6 = 3x
2 = x
Plug that in for 5x + 4
5(2) + 4
10 + 4
14
