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

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
