lidiya [134]

Answer:

Gain their trust back.  As someone who struggled with gaining trust I know that you just have to listen to them and gain it back.  Its going to be hard but I am also going into highschool next year.  For now tell them about your day and school work.  try and keep good grades because that will help you to slowly gain it back.  But if you do keep doing this bad stuff you went EVER get it back so for now just listen.  Having fun in highschool and having trust is so much better than fighting with your parents and not being allowed to do stuff.   And its going to take and long time so dont think that it will happen overnight.

Write an equation for the line through the point (−4,−2) and parallel to the line y=8x−3 in point-slope form y=y0+m(x−x0)
e-lub [12.9K]
If a line is parallel to another it means they have the same slope but different y-intercepts. This means the slope of the line we are trying to find is 8. We are also given a point that is on our line, so we are ready to use your variation of point-slope form.

y = -2 + 8(x--4) Cancel the double negative.
y = -2 + 8(x+4) Final Answer

N1=731pˆ1=0. 33 n2=644pˆ2=0. 28 use this data to find the 90onfidence interval for the true difference between the population pr
postnew [5]

The 90% confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]

Given,

N_{1} = 731

N_{2} = 644

P_{1} = 0.33

P_{2} = 0.28

z score for 90% confidence interval = 1.645

Here, the confidence interval formula :

( P_{1} -P_{2}) ± z \sqrt{\frac{P_{1}(1-P_{1})  }{N_{1} }+ \frac{P_{2}(1-P_{2})  }{N_{2} }  }

Substituting the values, we get

    (0.33 - 0.28) ± 1.645 \sqrt{\frac{0.33(1-0.33)}{731}+\frac{0.28(1-0.28)}{644}  }

=   0.05 ± 1.645 \sqrt{0.0003024624+0.0003130435}

=   0.05 ± 1.645 \sqrt{0.0006155059}

=    0.05 ± 1.645 × 0.0248093914

=    0. 05 ± 0.0408114489

Confidence interval:

- 0.05 - 0.0408114489 = - 0.0908114489 ≈ - 0.0908

- 0.05 + 0.0408114489 = - 0.0091885511 ≈ - 0.0092

The confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]
