Answer 1

Answer:

hey!

Step-by-step explanation:

question : -after eight matches, a basketball player had scored a mean of 27 points. after three more matches his mean was 29. calculate the total number of points he scored in the last three games .

ans . mean =  sum of total observation / no. of observations

ATQ,

let the sum of total points scored in 8 matches be x

x/8 = 27

x = 216

given :- after three more matches his mean was 29.

new mean = x + (points in last three games)/8+3

29 = x + (points in last three games)/11

x + (points in last three games)=  319

we know that x = 216

216  + (points in last three games) = 319

(points in last three games) = 319 - 216

∴ (points in last three games)=103
