The sum is 90 degrees then the angles are complementary angles. The value of x will be 35 degrees.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

We have

x + x - 20 = 90

          2x = 70

            x = 35

Then the value of x will be 35°.

More about the angled link is given below.

If a survey of a movie shows that 50% of all people who like the movie, enjoyed the official movie soundtrack too. If a total of
Murljashka [212]

Answer:

For the first question the sample size is n= 3850

ME= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

\hat p \pm ME

And replacing we got:

0.5- 0.016 = 0.484

0.5+ 0.016 = 0.516

We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.

Step-by-step explanation:

We have the following info given:

\hat p = 0.5 represent the estimated proportion of all people who like the movie

n = 3850 represent the sample size selected

For the first question the sample size is n= 3850

For the second part they gives to us the margin of error:

ME = 0.016

We know that the confidence interval for a population proportion p of interest is given by:

\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

And the margin of error is given by:

ME= z_{\alpha/2}\sqrt{\frac{\hat p(1-\hat p)}{n}}

So then the confidence interval can be found with this formula:

\hat p \pm ME

And replacing we got:

0.5- 0.016 = 0.484

0.5+ 0.016 = 0.516

We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.

Answer:

Step-by-step explanation:

x + 2y = 8

x - y = 2

x + 2y = 8

-x + y = -2

3y = 6

y = 2

x - 2 = 2

x = 4
