Answer:
82 kg
Step-by-step explanation:
To find the mean of a set of values, we must add them up and divide by the number of values.
Step 1, adding the values:
![75+68+78+82+85+90+88+92+76=\\734](https://tex.z-dn.net/?f=75%2B68%2B78%2B82%2B85%2B90%2B88%2B92%2B76%3D%5C%5C734)
Step 2, dividing by the # of terms:
There are 9 terms in total.
![\frac{734}{9} =\\81.556](https://tex.z-dn.net/?f=%5Cfrac%7B734%7D%7B9%7D%20%3D%5C%5C81.556)
To the nearest kilogram, we can round 81.556 into 82.
The mean mass of the 9 men was
kg.

Answer:
10
Step-by-step explanation:
Too add mixed numbers, first convert them to improper fractions:
34/5 + 53/10
Next, find a common denominator, which in this case is 10.
Convert 34/5 so that it has a denominator of 10 by multiplying the ENTIRE fraction by 2: 68/10
68/10 + 53/10 = 121/10
You can either give your answer in the form of an improper fraction: 121/10, or a mixed number 12 1/10
