Answer: ~2.45 cups, or A
Step-by-step explanation:
First, find the area of the circle. Area formula is , but instead of the radius, we have the diameter. Halve the diameter to get the radius of 10 inches.
A = pi * 100
So the pizza has an area of around ~314.15 square inches.
Divide this number by 16 square inches to find how many 1/8 cups Tony uses.
314.15/16 = ~19.63 1/8 cups.
You can then divide 19.63 by 8 to receive how many cups he uses.
Answer:
d. 2 in the numerator, 15 in the denominator
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have groups and on each group from
we have
individuals on each group we can define the following formulas of variation:
We want to test this hypothesis:
And we have this property
The degrees of freedom for the numerator on this case is given by where k =3 represent the number of groups.
The degrees of freedom for the denominator on this case is given by .
And the total degrees of freedom would be
On this case the correct answer would be 2 for the numerator and 15 for the denominator.
d. 2 in the numerator, 15 in the denominator
