Answer:

(7, 4)

Step-by-step explanation:

If point C is being translated to the right 2, the x coordinate will increase by 2. But, the y coordinate will stay the same.

Find the coordinates of C' by adding 2 to the original x coordinate:

5 + 2 = 7

The y coordinate will still be 4.

So, the coordinates of C' will be (7, 4)

Answer:

The 99% confidence interval estimate for the proportion of all 17-year-old students in 2012 who had at least one parent graduate from college is (0.4964, 0.5236).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

Sample of 9000, 51% of students had at least one parent who was a college graduate.

This means that $n = 9000, \pi = 0.51$

99% confidence level

So $\alpha = 0.01$ , z is the value of Z that has a pvalue of $1 - \frac{0.01}{2} = 0.995$ , so $Z = 2.575$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.51 - 2.575\sqrt{\frac{0.51*0.49}{9000}} = 0.4964$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.51 + 2.575\sqrt{\frac{0.51*0.49}{9000}} = 0.5236$

The 99% confidence interval estimate for the proportion of all 17-year-old students in 2012 who had at least one parent graduate from college is (0.4964, 0.5236).

For the scatter plot on homework:

a) The relationship is that the test score will increase, if the time spent on homework increases.

b) The function is y=8x+40, and what we need to see is what the score will be if someone puts in 3 hours of homework, x=3 in this because it means the time spent on homework:

y=8(3)+40

y=24+40

y=64

c) The score would be 40% if no time was spent doing homework.

For the scatter plot on the rides:

a) y = -7/5x + 17.8

b) Anika worked 17.8 hours on Day 0

c) Decreased by 7/5 in a day.

Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)
