Answer:
12x² - 5x - 2
Step-by-step explanation:
(3x - 2)(4x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(4x + 1) - 2 (4x + 1) ← distribute parenthesis
= 12x² + 3x - 8x - 2 ← collect like terms
= 12x² - 5x - 2

Answer:
The sample proportion is 0.36095.
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
The sample proportion is the halfway point betwen those two bounds, that is, the sum of those bounds divided by 2.
In this problem, we have that:
Lower bound: 0.2987
Upper bound: 0.4232
What is the sample proportion?
(0.2987 + 0.4232)/2 = 0.36095
The sample proportion is 0.36095.
