Step-by-step explanation:
Solve as requested in the question, round each number:
The sum is:
20 multiplied (times) 4 is equal to 80 c:
Answer:C
Step-by-step explanation:
C
We know that
<span>applying the Pythagorean theorem
c</span>²=a²+b²
c is the <span>length of the diagonal
a=100 yd
b=130 yd
c</span>²=100²+130²-------> c²=26900---------> c=√26900 units----> c=10√269 units
the answer is
the length of the diagonal is 10√269 units or 164.012 units
Answer:
D. the coefficient of determination is .81.
Step-by-step explanation:
<u>SST = SSE + SSR</u>
where
SST is the summation of square total
SSE is the summation of squared error estimate = 608
SSR is the summation of square of residual = 2593
with these in mind we put the values into the formula
= 2592 + 608
=3200
<u>Coefficient of determination = SSR/SST </u>
= 2592/3200
= 0.81
Therefore option D is the correct answer to the question.
