By the law of sines, $\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}$ where A, B, C are the angles and a, b, c are the lengths of the sides opposite their respective angles. In this case, $110^{\circ}$ is opposite 4.6 and A is opposite 3.2, so $\frac{sinA}{3.2}=\frac{sin(110^{\circ})}{4.6}$ , giving the answer.

Answer:

$y = 3^x$

Step-by-step explanation:

Less than 75% of workers got their job through internet resume sites. A researcher thinks it has increased.

Vera_Pavlovna [14]

Answer:

H0 : p = 0.75 against H1: p > 0.75 One tailed test.

Step-by-step explanation:

We state our null and alternative hypotheses as

H0 : p = 0.75 against H1: p > 0.75 One tailed test.

In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.

The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.

As H0 is supposed to be less than we choose H1 to be greater than equality.
