15. Since p=215. 851-p would be 851-215 which equals 636

18. Since a=6 and b=5 and c=3, ab/2 would be 6x5/2 which equals to 30/2. Now, you must add 30/2 to 4c. And again since c=3, it would be 4x3 which equals to 12. So now the equation would be 30/2+12. You must now turn the fraction into a whole number by 30÷2 which is 15. The question would now ask 15+12 so the answer would be 27

How many jelly beans are in a 2-liter jar? HELP ME PLEASE
Galina-37 [17]

1. The number of sample size 1 jelly beans in a 2-liter jar is <u>645</u>.

2. The number of sample size 2 jelly beans in a 2-liter jar is <u>640</u>.

3. The number of sample size 3 jelly beans in a 2-liter jar is <u>637</u>.

<h3>What is a mathematical operation?</h3>

A mathematical operation is an expression involving the use of mathematical operands and operators to compute values.

Mathematical operations use variables, numbers, and operators (addition, subtraction, division, and multiplication).

<h3>Data and Calculations:</h3>

Total weight = 1,150g

Weight of the jar = 440g

The total weight of the jelly beans = 710g (1,150 - 440)

Sample Size 1: the number of jelly beans = 645 (710/22.0 x 20)

Sample Size 2: the number of jelly beans = 640 (710/22.2 x 20)

Sample Size 3: the number of jelly beans = 637 (710/22.3 x 20)

Thus, the number of jelly beans in a 2-liter jar depends on the sample size of the jelly beans.
