Answer:
The answer is the option A
quadrant I
Step-by-step explanation:
Let
s-----> the length side of a cube
V----> the volume of a cube
we know that
the volume of a cube is equal to
The volume in function notation is
Remember that
The volume and the side length can not be a negative number
The domain and the range of the function are all real positive numbers
so
the graph of the function V(s) belong to the I quadrant

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.
