Sagot :

The mean height of the other 6 students is 140 cm if the 10 students have a mean height of 150 cm and 4 of the students have a mean height of 165 cm.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We know:

[tex]\rm mean = \dfrac{\sum x}{n}[/tex]

∑x = n × mean

∑x(10 students) = 10×150 = 1500

∑x(4 students) = 4×165 = 660

∑x(6 students) = 1500 - 660 = 840

Now the mean of 6 students:

mean = 840/6 = 140 cm

Thus, the mean height of the other 6 students is 140 cm if the 10 students have a mean height of 150 cm and 4 of the students have a mean height of 165 cm.
