Answer 1

Answer:

a. 17.7 b. 18

Step-by-step explanation:

add all the numbers and divide by how many variables there are (group nombor)

exp, (5+31+20+1+7+8+29+27+14+35)/10=17.7

Answer 2

Answer:

a.17.7

b.18

Step-by-step explanation:

To calculate the mean we will have to sum up the whole given value divided by the numbers

So let's solve

a. 5+31+20+1+7+8+29+27+14+35/10

177/10

17.7

Therefore the final answer is 17.7

b. Since another value is added

It will be

177+21/11

198/11

18

Therefore the final answer is 18
