Answer:

The experimental probability P(E) is 0.1818 = 18.18%

Step-by-step explanation:

The experimental probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

11 trials(11 outcomes)

2 kings(2 desired)

So

P(E) = 2/11 = 0.1818

The experimental probability P(E) is 0.1818 = 18.18%

4w2 + 3W

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

Length = 4w^2 + 3w - 1

Width = 5w - 2.

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

Area = 20w^3 + 7w^2 - 11w + 2

Step-by-step explanation:

Given

Length = 4w^2 + 3w - 1

Width = 5w - 2.

Required

Determine an expression for the area

Area is calculated as:

Area = Length *Width

Area = (4w^2 + 3w - 1) * (5w - 2)

Expand

Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2

Collect like terms

Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2

Area = 20w^3 + 7w^2 - 11w + 2
