\\ \sf\longmapsto A=(1-4)-(2+1)

\\ \sf\longmapsto A=-3-3

\\ \sf\longmapsto A=-6

\\ \sf\longmapsto B=(3-\dfrac{1}{2})-(2-4)

\\ \sf\longmapsto B=\left(\dfrac{5}{2}\right)+2

\\ \sf\longmapsto B=\dfrac{5+4}{2}

\\ \sf\longmapsto B=\dfrac{9}{2}

Now

\\ \sf\longmapsto AB=-6\times \dfrac{9}{2}

\\ \sf\longmapsto AB=-3(9)

\\ \sf\longmapsto AB=-27

BA

\\ \sf\longmapsto \dfrac{9}{2}\times (-6)

\\ \sf\longmapsto 9(-3)

\\ \sf\longmapsto -27

Observed:-

\\ \sf\longmapsto AB=BA

Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those
mestny [16]

The hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.

<h3>How to illustrate the information?</h3>

The following can be deduced from the information:

x1 = 275

x2 = 170

n1 = 500

n2 = 500

The sample proportion will be:

p1 = 275/500 = 0.55

p2 = 170/500 = 0.34

The pooled proportion will be:

= (275 + 170)/(500 + 500)

= 0.44

The test statistic is 6.681. It should be noted that the test statistics is a number that's calculated by a statistical test. It shows how the observed data are far from the null hypothesis.

The p value in this scenario is extremely small. The p value is a measurement used to validate a hypothesis against the observed data. Therefore, we have to reject the null hypothesis.

In this case, the hypothesis shows that we have evidence that the proportion surviving after eating organic is higher.

Answer:

D

Step-by-step explanation:

Angle 5 is equal to angle 8 because the two angles are an alternate interior angle. We already know that angle 7 and 8 are supplementary because it's adjacent to each other on a straight line. So, since angle 5 and 8 is equal to each other, angle 5 is also supplementary to angle 7.
