The first step for solving this is to distribute 5 through the parenthesis.
5b + 30 = 18
Now move the constant to the right side of the equation and change its sign.
5b = 18 - 30
Calculate the difference between the two numbers on the right side of the equation.
5b = -12
Lastly,, you need to divide both sides of the equation by 5.
b = -\frac{12}{5}
You can convert this fraction into a decimal by dividing the top of the fraction by the bottom. When you do this you should get -2.4 which will make the correct answer to your question option B.

- Given a test statistic of t= 3.018 of a left-tailed test with n= 13, use a 0.01 significance level
alina1380 [7]

Using the t-distribution, it is found that the correct option is:

0.005 < P-value < 0.01, reject the null hypothesis.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the mean of a given population is equal to 85, that is:

H_0: \mu = 85

We have a left-tailed test, hence, at the alternative hypothesis, it is tested if the mean of the population is less than 85, that is:

H_1: \mu < 85

<h3>What is the decision?</h3>

The test statistic is of t = -3.018.

Using a t-distribution calculator, with test statistic t = -3.018, 13 - 1 = 12 df and a significance level of 0.01, it is found that the p-value for a left-tailed test is of 0.0051.

The p-value is <u>less than 0.01</u>, hence the null hypothesis is rejected and the correct option is:

0.005 < P-value < 0.01, reject the null hypothesis.

Phoenix [80]

Answer:

48∛9 ft²

Step-by-step explanation:

Data

  • length = 4 ∛24 ft  
  • width = 6 ∛3 ft

The area of the rectangular region is computed as follows:

area = length * width

area = 4 ∛24 * 6 ∛3

area = 4*6* ∛(24*3)

area = 24 * ∛(2³*3*3)

area = 24 * 2∛9

area = 48∛9 ft²
