Question

' Erin has 10 bags of apples. Thefollowing are the weights of the bags in pounds: 2223. 23, 2, 14, 22, 23, 24, 24, 24. Write an expressionthat shows the average weight of a bag. Evaluate theexpression.

Answer 1

Given the weight of the 10bags of apples below,

`2(1)/(2),2(3)/(4),2(1)/(2),2(1)/(4),1(1)/(4),2(1)/(2),2(1)/(2),1(1)/(4),2(1)/(4),2(1)/(4)`

The formula for average(Mean) is,

`\text{Average}=\frac{Sum\text{ of numbers}}{\text{Amount of numbers}}`

The sum of the weight is,

`2(1)/(2)+2(3)/(4)+2(1)/(2)_{}+2(1)/(4)+1(1)/(4)+2(1)/(2)+2(1)/(2)+1(1)/(4)+2(1)/(4)+2(1)/(4)=22`

The amount of the weight = 10

Hence, the expression that shows the average weight of the bag is,

`\text{Average = }\frac{\text{22}}{10}\text{pounds}`

Let us now evaluate the expression

`\text{Average}=2(1)/(5)\text{ pounds or 2.2pounds}`

Hence, the answer is

`2(1)/(5)\text{pounds or 2.2pounds}`
