<span>We need to divide 72 rolls into 2 groups so that their ratio is 3:5. First, we can see that the ratio of 3:5 tells us there is 8 separate groups of rolls. Now its easy, since we have 72 rolls and we need to divide them into 8 equal groups: 72/8=9. So each group has 9 rolls. Now we separate them into groups with the ratio 3:5, so: 3*9:5*9 and that is: 27 rolls and 45 rolls. </span>
Sort the data into this order:
2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2
^
there are 10 data points in total, therefore the Interquartile Range = between the 5th and the 6th numbers, which are 5 and 6
(5+6)/2= 5.5
(X+7)-(x-2)=24..... given equation..
Remove the bracket.
X+7-x+2=24
# 15 is the final answer.
Hope it helped.
I apologise if it’s wrong.
