Question

a recycling center kept a log of how many glass bottles were recycled in the past 5 days. what is the mean of the numbers?

Explanation:

Step1: Identify the data values

From the bar - chart, the number of bottles recycled each day are: 6000 (Sunday), 9500 (Monday), 5500 (Tuesday), 2500 (Wednesday), 4500 (Thursday).

Step2: Use the mean formula

The mean formula is $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $n$ is the number of data - points and $x_{i}$ are the individual data - points. Here, $n = 5$, and $\sum_{i=1}^{5}x_{i}=6000 + 9500+5500 + 2500+4500=28000$.

Step3: Calculate the mean

$\bar{x}=\frac{28000}{5}=5600$.

Answer:

5600
