Answer:
The answer is A
Step-by-step explanation:
Fist multiply 3 and .15 to get .45 for 3 pencils. Then subtract .45 from 6.45 and get 6. Then divided 6 by 5 to get 1.2 for each book
You take 80 words per minute × how many minutes which is 30 which will equal 2400.
Just add the like terms together.
Answer:
a) The new correlation coefficient should be the same: R = 0.72
Step-by-step explanation:
The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.
It is a relative dimensionless measure, so it does not depend on the units of measurement of the variables involved.
If the variables are correlated in centimeters and kilograms, they will also be correlated in inches and pounds, and with the same relative magnitude.
So the answer is
a) The new correlation coefficient should be the same: R = 0.72
