Answer:
The flower garden width would be 6 ft
Step-by-step explanation:
A = 12 ft^2 = x(x + 4) becomes:
x^2 + 4x - 12 = 0, or (by completing the square) x^2 + 4x + 4 - 4 - 12 = 0
Thus, we have (x + 2)^2 - 16 = 0, or (x + 2)^2 = 16
Taking the square root of both sides yields x + 2 = ±4.
In this context only a positive x value makes sense: x = 2 + 4 => x = 6.
The flower garden width would be 6 ft. The other dimension would be 6 - 4, or 2, ft.
Using it's concept, the desired probability is given as follows:
P(decaf or sugar) = 0.41.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. A probability can also be represented as a proportion.
From the table, we have that:
- P(decaf) = 0.05 + 0.08 + 0.09 = 0.22.
Hence:
P(decaf or sugar) = 0.22 + 0.19 = 0.41.
