Please help!! ASAP!!

Answer:

Explained below.

Step-by-step explanation:

(1)

The confidence level is, 91%.

Compute the value of α as follows:

[tex]\text{Confidence level}\% =(100-\alpha \%)\\\\91% = 100-\alpha \%\\\\\alpha \%=100-91\%\\\\\alpha \%=9\%\\\\\alpha =0.09[/tex]

(2)

As the population standard deviation is provided, i.e. σ = 256 psi, the z value would be appropriate.

The z value for α = 0.09 is,

z = 1.69

(3)

Compute the 91% confidence interval as follows:

[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

     [tex]=3000\pm 1.69\cdot\frac{256}{\sqrt{70}}\\\\=3000\pm 51.71\\\\=(2942.29, 3057.71)[/tex]

(4)

The 91% confidence interval for population mean implies that there is a 0.91 probability that the true value of the mean is included in the interval, (2942.29, 3057.71) psi.

Answer:

7.2 km

Step-by-step explanation:

Distance between Brookfield to Seaside = 20.4 km

Distance between Yardley and Seaside = 13.2 km

Let distance between Brookfield to Yardley be x.

Thus:

x + 13.2 km = 20.4 km

Subtract 13.2 from each side

x = 20.4 - 13.2

x = 7.2

Distance from Brookfield to Yardley is 7.2 km

Answer:

angle 4 (the exterior angle) = 101°

Answer:

101

Step-by-step explanation:

first , let angle 4 be x

then

x =52+ 49 (exterior angle of a triangle is equal to sum of opposite interior angles)

=101

Answer:

They suggest that the audience has listened to and understood all of Truth’s reasons.

Step-by-step explanation:

Obliged to you for hearing me, and now old Sojourner ain’t got nothing more to say.

This Implies that she needs to say nothing more, because the truth was so blaringly obvious that everyone in the crowd understood it. It also implies that no better argument for her cause could be put forward, and none was needed.

The statement that most adequately recounts the impact of the given words is:  Option A: They remind the audience that Truth has had rich life experiences and offers valuable wisdom.

From the story of "Ain't I a Woman?", we can see that Sojourner is a strong-headed woman that had gone through serious battles all her life in seeking equal rights of women.

Finally, words used like "obliged" and "old" are descriptive words that help show us that she is a humble, and experienced person.

In conclusion, the correct answer is Option A.

Answer:

  see below

Step-by-step explanation:

I find it convenient to factor 5 from the equation and re-order the left side:

  y -2x = 3

This makes it relatively easy to see that the values in the left-most table will satisfy this equation.

__

If we look at the table values for x=2, where all the tables differ, we can easily find the one that works:

  1.  7 -2(2) = 3 . . . . this value works in the equation

  2.  0.5 -2(2) = -3.5 . . . . no

  3.  -1 -2(2) = -5 . . . . no

  4.  2.5 -2(2) = -1.5 . . . . no
