I guess you want to calculate the value of e. If so then:

-8.e = 4 . Divide both sides by 4:

-2.e = 1. Divide both sides by 2:
-e = 1/2. Multiply both sides with (-):

e = - 1/2

Marianna [84]
<h2>Answer with explanation:</h2>

Given : A store owner claims that the proportion of shoppers who use coupons is less than 25%.

Then , the null hypothesis and the alternative hypothesis will be :-

H_0: p\geq0.25\\\\H_1:p, since the alternative hypothesis is left tailed , so the test is a left tailed test.

Also,t the test statistic for this hypothesis test is −1.17 and the critical value for this hypothesis test is −1.282 .

We know that when the test statistic value if greater than the critical value , then we reject the null hypothesis.

Here  test statistic value(−1.17 ) is greater the critical value(−1.282) for this hypothesis , so we reject the null hypothesis.

So we conclude that there is enough evidence to support the claim.

Need help with questions <br> 2. and 3.

Answer:

  2)  x = 7

  3)  x = 5

Step-by-step explanation:

When a transversal crosses parallel lines, all of the acute angles are congruent, and all of the obtuse angles are congruent. When it crosses at right angle, all of the angles are right angles.

2) All of the angles are right angles.

  11x +13 = 90

  11x = 77 . . . . . . subtract 13

  x = 7 . . . . . . . divide by 11

__

3) The two marked angles are acute.

  16x = 80 . . . . the acute angles are congruent

  x = 5 . . . . . . divide by 16
