Answer:
(-7)*(-8)
Step-by-step explanation:
Two negatives make a postive so 7*8=56 and 4*6=24.
Answer:
The points that are exactly 10 units from the point (–8, –2) are (2, –2) and (–8, 8).
Step-by-step explanation:
The distance formula is;
d= 
So for distance between: (–8, –2) and (2, –2) is:
d= 
d= 
d= 10 unit
Similarly for distance between: (–8, –2) and (–8, 8) is,
d= 
d= 
d= 10 unit
Answer:
b. CHISQ.TEST
Step-by-step explanation:
Notation and previous concepts
A chi-square test is "used to test if the variance of a population is equal to a specified value. This test can be either a two-sided test or a one-sided test. The two-sided version tests against the alternative that the true variance is either less than or greater than the specified value"
The statistic is given by:

In order to calculate the p value we need to have in count the degrees of freedom , on this case
. And we can calculate the p value would be given by:
But the correct comand is given by:
b. CHISQ.TEST(Actual range, Expected range)
We just need to put in one column the Observed values and in other the expectec values.
