A hat contains four balls. The balls are numbered 2, 4, 4, and 7. One ball is randomly selected and

Answer:

If the sum is 6, a small cone will be ordered.
If the sum is 8 or 9, a medium cone will be ordered.
If the sum is 11, a large cone will be ordered.

Step-by-step explanation:

The table below shows the possible outcomes from drawing two balls. We see the relative frequencies to be ...

6: 4

8: 2

9: 2

11: 4

To make a fair decision, we want the relative frequencies of the decision possibilities to be the same. If we combine sums 8 and 9 to one category (medium cone, for example), then 6, (8 or 9), and 11 will all have the same relative frequency: 4.

The appropriate "fair decision" choice is ...

6: small cone

8 or 9: medium cone

11: large cone

Henry combines 7.49 litters of red paint with 6.26 litters of red paint and pours it in to 4 container with 0.43 litters of pain

11111nata11111 [884]

To find the answer we start by adding the contents of both containers together
7.49 + 6.26 = 13.75
Since we know that there is leftover paint we are going to subtract the leftovers from the total of combined paint
13.75 - 0.43 = 13.32
The combined paint is poured into 4 containers so we divide our combined total minus the leftovers by 4
13.32/4 = 3.33
Answer: There are 3.33 liters of paint in each container
