Why could the mean of the data set below be misleading? ages of teachers: 29, 38, 39, 26, 29, 29, 39, 77, 38, 29

1 answer:

8 0

The mean of the problem is 37.3. All you need to do is add all the numbers together and then divide them by the amount of numbers. So I added them all and divided by 10.

H + 52 72<br> ———- = —-<br> 70. 56

oee [108]

Answer:

h = 38

Step-by-step explanation:

$\frac{h + 52}{70} = \frac{9}{7}$

$h + 52 = \frac{9}{7} \times 70$

$h + 52 = \frac{9 \times 70}{7}$

$h + 52 = \frac{630}{7}$

$h + 52 = 90$

$h = 90 - 52$

$h = 38$

the answer is 38.
