Answer:
Step-by-step explanation:
Given that a professor sets a standard examination at the end of each semester for all sections of a course. The variance of the scores on this test is typically very close to 300.

(Two tailed test for variance )
Sample variance =480
We can use chi square test for testing of hypothesis
Test statistic = 
p value = 0.0100
Since p <0.05 our significance level, we reject H0.
The sample variance cannot be claimed as equal to 300.
answer: Subtract sixteen from both sides of the equation
2 +16 -16=22x -16
x = 4/5
Answer:
26 2/3 yards,
Step-by-step explanation:
First convert 3 1/3 to an improper fraction:
3 1/3 = (3*3 + 1) / 3 = 10 /3.
So for 8 quilts we need (10/3) * 8
= 80/3
= 26 2/3 yards,
Answer:
Terms: 6m , -2n, 7
Coefficients: 6, -2
Constants: 7
Step-by-step explanation:
terms are the parts of the expression so 6m, -2n and 7
coefficients are the numbers in fron tof variables so 6 and -2
constants are terms without variables so 7
