r/5 - 6 = -1

add 6 to both sides

r/5 = 5

multiply both sides by 5

r = 5 *5 = 25

r = 25

The inequality written in interval notation is therefore -4<x<-1  or (-4, -1)

<h3 /><h3>What are inequalities?</h3>

Inequalities are expressions separated by the mathematical inequalities ≤, ≥, < and >

For instance a < b is a form of inequality.

<h3>What is a number line?</h3>

A number line is a line on which numbers are marked at intervals, used to illustrate simple numerical operations.

From the given number line, we can see that closed circles are on -4 and -1. The inequality written in interval notation is therefore -4<x<-1  or (-4, -1)

         (45 gal/day) x (31 day/Dec) =

               (45 x 31) (gal/Dec) = <em>1395 gallons</em> per December .

Choice-B is closer to that figure than Choice-A is,
but they're both poor estimates.

given that a test statistic in a left tailed test is z equals -1.25, use a 0.05 significance level to find the p-value and state
mr Goodwill [35]

Answer:

The <em>p-</em>value of the test is 0.106.

The null hypothesis will be accepted at 5% level of significance.

Step-by-step explanation:

The hypothesis test is left-tailed.

The test statistic value is: <em>z</em> = -1.25.

The significance level of the test is: <em>α</em> = 0.05.

The <em>p</em>-value of a left-tailed hypothesis test is:

p-value=P(Z

The <em>p-</em>value of the test is 0.106.

**Use the <em>z-</em>table for the probability.

<u>Decision rule:</u>

If the <em>p</em>-value is less than the significance level the null hypothesis will be rejected and if it is more than the significance level the null hypothesis will be accepted.

The <em>p</em>-value = 0.106 > <em>α</em> = 0.05.

The null hypothesis will be accepted at 5% level of significance.
