Answer:
1 solution
(3, 4)
Step-by-step explanation:
The pair of equations for lines A and B have 1 solution because there is one point of intersection.
The point of intersection is (3, 4), therefore this is the solution.
Answer:
The percentage [regression line is unexplained] = 60.6%
Step-by-step explanation:
Given:
Coefficient of determination = 0.394
Find:
The percentage [regression line is unexplained]
Computation:
Coefficient of determination = 0.394
Coefficient of determination = 39.4%
The percentage [regression line is unexplained] = 100% - Coefficient of determination
The percentage [regression line is unexplained] = 100% - 39.4%
The percentage [regression line is unexplained] = 60.6%
Answer:
3 2/6
Step-by-step explanation:
<u>total pages to be written</u>
add 4 to 1/2 using common denominators
4 1/2 = 8/2 + 1/2
= 9/2 or 27/6
<u>pages Marcus wrote</u>
add 1 to 1/6 using common denominators
1 1/6 = 6/6 + 1/6
= 7/6
<u>pages left</u>
27/6 - 7/6 = 20/6 or 3 2/6
They should get 2 each cause 2 goes into 90 and 72 so 2 is your answer
The answer is n=0 because 9x0 is 0
