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.
Answer: C y=1/3x
Step-by-step explanation:
All Y-values in the table are 1/3 of the corresponding X-value. To check: 3/1=1, 6/3=2, 9/3=3
A, because negative is not rational
Answer:
x=
1/2
Step-by-step explanation:
6x+9=12
Step 1: Subtract 9 from both sides.
6x+9−9=12−9
6x=3
Step 2: Divide both sides by 6.
6x/6=
3
/6
And Your Answer Will Be:
x=
1/2
