Ten engineering schools in the United States were surveyed. The sample contained 250 electrical engineers, 80 being women; 175 c
steposvetlana [31]

Answer:

There is a significant difference between the two proportions.

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for difference between population proportions is:

CI=(\hat p_{1}-\hat p_{2})\pm z_{\alpha/2}\times\sqrt{\frac{\hat p_{1}(1-\hat p_{1})}{n_{1}}+\frac{\hat p_{2}(1-\hat p_{2})}{n_{2}}}

Compute the sample proportions as follows:

\hat p_{1}=\frac{80}{250}=0.32\\\\\hat p_{2}=\frac{40}{175}=0.23

The critical value of <em>z</em> for 90% confidence interval is:

z_{0.10/2}=z_{0.05}=1.645

Compute a 90% confidence interval for the difference between the proportions of women in these two fields of engineering as follows:

CI=(\hat p_{1}-\hat p_{2})\pm z_{\alpha/2}\times\sqrt{\frac{\hat p_{1}(1-\hat p_{1})}{n_{1}}+\frac{\hat p_{2}(1-\hat p_{2})}{n_{2}}}

     =(0.32-0.23)\pm 1.645\times\sqrt{\frac{0.32(1-0.32)}{250}+\frac{0.23(1-0.23)}{175}}\\\\=0.09\pm 0.0714\\\\=(0.0186, 0.1614)\\\\\approx (0.02, 0.16)

There will be no difference between the two proportions if the 90% confidence interval consists of 0.

But the 90% confidence interval does not consists of 0.

Thus, there is a significant difference between the two proportions.

Simplify the following expression.<br> 3^3/5• 3^(-7/5)
ad-work [718]

Answer:

\frac{1}{3x^{\frac{4}{5}}}

Step-by-step explanation:

Subtract the exponents: 3/5 - 7/5 = -4/5

Equation would become 3^-4/5

Which is equivalent to 1/3x^4/5

Choose the abbreviation of the postulate or theorem that supports the conclusion that the triangles are congruent.
Ber [7]

Answer:

Option D.

LA Theorem or Postulates

Explanation:

LA theorem or postulates is leg-acute states that if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.

In \triangle ACB and  \triangle DFC

\angle C =\angle F = 90^{\circ}             [Given]

\angle B = \angle E   [Acute angle]      [Given]

BC=EF        [Given]

By LA theorems or postulates,

\triangle ACB \cong \triangle DFE

Therefore, LA theorems or postulates support the conclusion that the triangles are congruent.

First answer gets the best marks ​
Delicious77 [7]

Answer:

<h2><em><u>B or the second one</u></em></h2>

Step-by-step explanation:

This is because you have the equation of 2(2/5x + 2).

When you simplify it you have to first do the parenthesis.

So, 2 * 2/5 = 4/5. This is because 2/1 *2/5 is 4/5.

Then you have to do 2*2. This is equal to 4.

Put them together. So it will be.

<h2><u><em>4/5x + 4.</em></u></h2>
