Question

the number of pizzas delivered by papa johns over the last 7 days has as follows: 28, 17, 18, 21, 24, 30, 30. what is the mean or average number of pizzas delivered daily?

Explanation:

Step1: Sum up all the numbers

$$28 + 17+18 + 21+24 + 30+30$$
$$=(28+17)+(18 + 21)+(24 + 30)+30$$
$$=45+39+54 + 30$$
$$=(45+39)+(54 + 30)$$
$$=84+84$$
$$=168$$

Step2: Divide the sum by the number of data points

The number of data points \(n = 7\). The mean \(\bar{x}=\frac{168}{7}=24\)

Answer:

\(24\)
