The following are the last 10 run scores Colin got in cricket: 22, 35, 33, 18, 16, 12, 28, 18, 1, 16
a) Work out Colin's mean score.
b) Colin plays cricket again on Sunday. He gets 10 runs.
What is his new mean score?
Give your answers as decimals.

a) 22+35+33+18+16+12+28+18+17 is 199, and 199 divided by 10 is 19.9, so 19.9 is the mean.

b) if he gets 10 more home runs, then he has 209 divided by 11 which is 19

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
