Answer:
I assume you meant 4x^2
So the answer in simplified form is -4x^2-11x+3
B at least 70% i had the same question before and that was correct
-22 = -2x + 9
-31 = -2x
-31/-2 = x
x = 15.5
Answer:
D. there is more variability among female students with respect to GPA
Step-by-step explanation:
The standard deviation is a measure of how spread out from the mean the values within a set are. If the standard deviation for females is much higher, that means that the variability in GPAs for female students is higher than that of male students.
Therefore, it is fair to conclude that there is more variability among female students with respect to GPA.
