I believe the correct answer would be A. The best correlation to use to measure the relationship between gender and grade point average for a group of college students would be the point-biserial correlation. It is coefficient that is used when a variable is dichotomous or that the variable is part of a whole set. It is used in measuring the direction of the correlation that is present between a dichotomous variable and a continuous variable. From the question, the dichotomous variable would be the grade point average for a group of college students while the other variable is the continuous one.
The quotient of z and 3.
quotient = ÷
z/3
The answer is A.

Sum of three consecutive odd integers = 

The values of the three integers.



Let us assume the three consecutive odd integers to be
,
and
.
As per the condition, we have



Now, collect the like terms.






Therefore, the three consecutive odd integers whose sum is
are
,
and
respectively.

Well if you subtract 437.5 from 500 you get 62.5 that is the difference between them but in fraction form it would be 5/8.
