The heights of the five starters of a college basketball team are 6'6, 6'7, 6'9, 6'11 and 7'. What it the mean height of these players , in inches?
To find the mean height of the players, you need to calculate the sum of their heights and then divide it by the number of players. Here are the steps to find the mean height:
1. Convert all the heights to inches:
- 6'6 = (6 * 12) + 6 = 78 inches
- 6'7 = (6 * 12) + 7 = 79 inches
- 6'9 = (6 * 12) + 9 = 81 inches
- 6'11 = (6 * 12) + 11 = 83 inches
- 7'0 = (7 * 12) + 0 = 84 inches
2. Add up the heights:
78 + 79 + 81 + 83 + 84 = 405 inches
3. Divide the sum by the number of players (5):
405 / 5 = 81 inches
Therefore, the mean height of the players is 81 inches.
To find the mean height of the players, we need to add up the heights of all the players and then divide the sum by the number of players.
First, let's convert the heights from feet to inches:
- 6'6 = 6 * 12 + 6 = 72 + 6 = 78 inches
- 6'7 = 6 * 12 + 7 = 72 + 7 = 79 inches
- 6'9 = 6 * 12 + 9 = 72 + 9 = 81 inches
- 6'11 = 6 * 12 + 11 = 72 + 11 = 83 inches
- 7' = 7 * 12 + 0 = 84 inches
Now, we add up the heights:
78 + 79 + 81 + 83 + 84 = 405 inches.
Since there are five players, we divide the sum by 5 to find the average or mean height:
405 / 5 = 81 inches.
Therefore, the mean height of these players is 81 inches.
