Question

1. the table shows the weekly profits of a fruit vendor. what is the mean profit for these weeks?

Explanation:

Step1: Sum all profits

$$- 125+( - 86)+54+( - 35)=-125 - 86+54 - 35=-(125 + 86+35)+54=-246 + 54=-192$$

Step2: Calculate the mean

The number of weeks \(n = 4\). The mean formula is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). So \(\bar{x}=\frac{-192}{4}=-48\)

Answer:

\(-48\)
