Question

A company is creating a rectangular prism that must have a volume of 6 ftÂ³. The company also knows that the area of the base must be 2 1/2 ftÂ². How can you use what you learned today about volume to determine the height of the rectangular prism?

Solution 1

**Answer:**

The height is 2 2/5 or 2.4 ft

**Step-by-step explanation:**

The volume of a rectangular prism can be found with the formula:

volume = Area of the base * height

So you have to substitute the information on that ecuation and solve for the height.

6 ftÂ³ = 2 1/2 ftÂ² * height

height = 6 ftÂ³ / 2 1/2 ftÂ²

height = 2 2/5 ft or 2.4ft

Question

A soccer team won 65% of his matches and 15% of its matches ending to draft a team is scheduled to play 20 matches about how many matches is it expected to lose

Solution 1

**Answer:**

4 matches

**Step-by-step explanation:**

The probability of winning is 65%, the probability of a draw is 15%. So the probability of lossing a match is

100% - 65% - 15% = 20%

Now that you know the probability of lossing, you have to multiply it by the number of matches

P(lossing) = 20 * 20%

P(lossing) = 20 * (20/100)

P(lossing) = 20 * 0.2

P(lossing) = 4
