Gabrielle surveyed a random sample of 40 students in her school's cafeteria about whether they ate the cafeteria's tomato soup.

1 answer:

8 0

Part A:
14/40=x/840
14*840=40x
11760=40x
294=x
x=294
194 are expected to eat the tomato soup

Part B:
find the average of 10,11, and 14
35/3=11.67

11.67/40=x/840
40x=11.67*840
9802.8=40x
x=245.07

245.07/840
0.29175*100 = 29.175

29.175%

First, you must make common denominators...
5/6 pound = 25/30 pound
1/5 pound = 6/30 pound

Then, you must subtract
25/30 - 6/30 = 19/30

Finally, divide the remainder by 8, or multiply by the reciprocal
19/30 • 1/8 = 19/240
