The following are the last 10 run scores Colin got in cricket:

5, 31, 20, 1, 7, 8, 29, 27, 14, 35

a) Work out Colin's mean score.

b) Colin plays cricket again on Sunday. He gets 21 runs.

What is his new mean score?

Give your answers as decimals.

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

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
