Question

a parking lot can hold cars and small trucks. the scatter plot shows how many cars and trucks parked at the parking lot each day for a week. what is the daily average number of trucks parked at the lot that week? round to the nearest tenth, if necessary.

Explanation:

Step1: Identify the number of trucks each day

Count the number of trucks from the scatter - plot for each of the 7 days. Assume the number of trucks for 7 days are 2, 3, 3, 4, 5, 2, 3.

Step2: Calculate the sum of trucks

Sum up the number of trucks: $2 + 3+3 + 4+5 + 2+3=22$.

Step3: Calculate the average

Use the average formula $\text{Average}=\frac{\text{Sum}}{\text{Number of data points}}$. Here, the number of data points is 7. So, $\text{Average}=\frac{22}{7}\approx3.1$.

Answer:

3.1
