Answer:

(x + 4)(x - 3)

Step-by-step explanation:

Given

x² + x - 12

Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (+ 1)

The factors are + 4 and - 3 , since

4 × - 3 = - 12 and 4 - 3 = + 1 , then

x² + x - 12 = (x + 4)(x - 3) ← in factored form

Answer:

The p-value is 0.0577.

Step-by-step explanation:

The alternate hypothesis is:

$H_1: p > 40\%$

P-value of the test:

The p-value of the test is the probability of finding a sample proportion above the one found, which is 1 subtracted by the p-value of z.

We have that z = 1.574.

Looking at the z-table, z = 1.574 has a p-value of 0.9423

1 - 0.9423 = 0.0577

The p-value is 0.0577.
