Answer:
Correlation Coefficient
Step-by-step explanation:
The correlation coefficient (r) is a numerical measure that measures the strength and direction of a linear relationship between two quantitative variables.
Answer:
C. 10
Step-by-step explanation:
Let x and y represent push-ups and pull-ups, respectively.
x + y = 24 . . . . . . combined total of push/pull-ups
2x +4y = 68 . . . . time required for the exercise
We can divide the second equation by 2 and subtract the first:
(1/2)(2x +4y) -(x +y) = (1/2)(68) -(24)
x +2y -x -y = 34 -24 . . . . . eliminate parentheses
y = 10 . . . . . . . . . simplify
Malia did 10 pull-ups.
__
She did 14 push-ups.
I hated remainders but eventually you'll learn to make it a decimal so that what you will do is continue by our long division so instead of a remainder of 3 you'll add a decimal and continue your division! It's hard to explain through words and no examples but remember there are no remainders, there are decimals that are waiting to be included, sorry if this wasn't helpful. It's hard to explain over words
