Out of 22 players in a team, 10 of them have an average height of 1.50m while another 10 have an average height of 1.48m. The remaining players had an average height of 1.60m. What is the mean height of the team ?

1.5 meters

Step-by-step explanation:

We know that the sum of all of the data in a set = average * number of data.

Therefore, the sum of the first 10 is 1.5 * 10 = 15 meters, the sum of the second 10 is 1.48 * 10 = 14.8 meters and the sum of the last 2 is 1.6 * 2 = 3.2 meters for a total of 15 + 14.8 + 3.2 = 33 meters. This means that the mean is 33 / 22 = 1.5 meters.

{3 + i, 3 - i, 3, -1}

5x+10 is the correct one
