Answer:

135°

Step-by-step explanation:

The sum of interior angles in this rectangle is equal to 720

Two of the angles are right (has 90°)

so 4x + 180 = 720 subtract 180 from both sides

4x = 540 divide both sides by 4

x = 135°

Which correlation should be used to measure the relationship between gender and grade point average for a group of college stude
Alecsey [184]
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.
