1.6z + 8.3 z = ? (9.9z)

6.2y - 5.1y = ? (1.1y)

4.3x + 5.5x = ? (9.8x)

Find the population mean or sample mean as indicated. ​population: 44​, 22​, 1111​, 1717​, 2121
vlada-n [284]
The mean of the sample given by 44,22,11,17,21 will be given by:
\mu= \frac{\Sigma  x_i}{n}
the sum of x's will be:
44+22+11+17+21
=115
n=5
therefore the mean will be:
μ=115/5
=23
