Answer:

(x + 9)(x + 2)

Step-by-step explanation:

x² + 11x + 18

consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (+ 11)

the factors are + 9 and + 2 , since

9 × 2 = 18 and 9 + 2 = 11 , then

x² + 11x + 18 = (x + 9)(x + 2)

Answer:

The test statistics is $z = -1$

Step-by-step explanation:

From the question we are told that

The sample size is n = 100

The null hypothesis is $H_o : \mu = \$30000$

The alternative hypothesis is $H_a : \mu < \$ 30000$

The sample mean is $\= x = \$29,750$

The standard deviation is $\sigma = \$2,500$

The level of significance is $\alpha =0.05$

Generally the test statistics is mathematically represented as

$z = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

=> $z = \frac{29750 - 30000 }{ \frac{ 2500}{ \sqrt{100} } }$

=> $z = -1$
