For this kind of questions, we need to check the problem carefully...
So there are 45 pupils all in all, and 9 of them gave their sweets away... Therefore, the rest of pupils would be 45-9= 36.
These 36 pupils then got 2 more sweets than they originally have. We can then set x as the number of candies they originally got.
We will then create an equality, since the total number of candies is the same in the 2 scenarios: a) all 45 pupils have candies b) 36 pupils get 2 more
45x = 36(x+2)
45x = 36x + 72
45x - 36x = 72
9x = 72
x = 8 candies
Total number of candies would then be 45x which is 45(8) = 360 candies.
Answer:25
Step-by-step explanation:
For the first one, the range is the largest number minus the smallest number. The largest number in this case is 11 and the smallest is 4. 11 - 4 = 7 so the maximum range is 7 inches.
For the second one, the IQR is Q3 - Q1. This means 30 - 20 = IQR and 30 - 20 is 10 books.
And the last one asks for dinner customers, and there are 54 total. 28 of them chose cheesecake as their favorite dessert. This means that the amount of dinner customers that chose cheesecake as their favorite is 28/54 or 0.5185, whihc is 51.85%
Hope this helps!!
