Question

customers at a sandwich shop are given a pull - tab card with every purchase, and every card is a winner. bella has received 10 cards, with her winnings of: $8.00 $7.00 $8.00 $6.00 $7.00 $8.00 $6.00 $8.00 $4.00 $8.00 what was the mean amount won? $\square$

Explanation:

Step1: Sum all the winnings

First, we add up all the winning amounts: \(8 + 7 + 8 + 6 + 7 + 8 + 6 + 8 + 4 + 8\)
Let's calculate step by step:
\(8+7 = 15\); \(15 + 8 = 23\); \(23+6 = 29\); \(29 + 7 = 36\); \(36+8 = 44\); \(44+6 = 50\); \(50+8 = 58\); \(58+4 = 62\); \(62+8 = 70\)
So the total sum of winnings is \(70\) dollars.

Step2: Calculate the mean

The mean is calculated by dividing the total sum by the number of data points. Here, the number of cards (data points) is \(10\).
Mean \(=\frac{\text{Total Sum}}{\text{Number of Data Points}}=\frac{70}{10} = 7\)

Answer:

\(7\)
