If 500 high school students, 376 said they would prefer to have computers in every classroom then the confidence interval at 95% is (71.41%,78.99%)  Since option (a) is correct.

Given x= 376, n = 500

The (71.41%,78.99%)  

\hat{p}=\frac{x}{n}\\ =\frac{376}{500} \\=0.752

Critical values

Using the z-table the z-critical value at the given significance level at α=0.05 is,z_{a/2} =1.96

Construct a 95% confidence interval

That is,

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

  =0.752\pm 1.96\sqrt{\frac{0.752(1-0.752)}{500} }

  =0.752\pm 0.0379

  = (71.41%,78.99%)

Answer:

(-1, 5) and (3, -3)

Step-by-step explanation:

The solutions are all the points where the two functions intersect. Since the lines intersect at two different points, there are two solutions.

The two points at which the functions appear to intersect are (-1, 5) and (3, -3).

Keisha is walking around a track that is 400 yards long. She has walked around the track 5 times so far. How many more yards doe
iragen [17]
Dear Carlaac04,
To answer this questions you need to know that there are 1,760 yards in a mile. Multiply that by 2 and you get 3,520 yards. Next you multiply 400 by 5, because the each track is 400 yards and Keisha walked 5 tracks, which is equal to 2,000. Lastly, you subtract 2,000 from 3,250 which is equal to 1520 yards.
