Answer:
Well, first, you have to find out how much food each person needs. Assuming everyone eats the same amount, you divide 24 by 6, getting 4 meatballs per person. Then you divide the 4 pounds of pasta by 6, getting .75 pounds of pasta per person. Then you multiply both of those numbers, 4 and .75 by 8, since that is how many people will be eating that night. You get 32 meatballs, and 6 pounds of pasta.

Hope this helps.
1st Step - Find the mean (average):
245 + 300 + 325 + 465 + 100 = 1435
1435/5 = 287 ( mean)
2nd step find the sun of the sqaure the difference between the gievn data and the mean
287 - 245 = 42^2 = 1,764
300 - 387 = 13^2 = 169
325-287 = 38^2 = 1,444
465 - 287 = 178^2 = 31,684
287 - 100 = 187^2 = 34,969
1,764 +169 + 1,444 + 31,684 + 34,969 = 70,030
Now divide that by the number of samples minus 1 ( 5-1=4)
70,030 / 4 = 17,507.5
The variance = 17, 507.5
Answer:
140 in^3
Step-by-step explanation:
The volume formula can be written as ...
A = Bh
Marcia found B = 20 in^2, so we can use that in the formula, along with h = 7 in.
A = (20 in^2)(7 in)
A = 140 in^3
The volume of the box is 140 cubic inches.
