Answer:

-7 is the pattern in the sequence. In other words, we subtract 7 from the numbers.

Step-by-step explanation:

31 - 7= 24

24 - 7= 17

17 - 7= 10

We subtract 7 from 31 to get 24. We subtract 7 from 24 to get 17. We subtract 7 from 17 to get 10.

luis spent 8.75 on snacks at a basketball game. candy costs 1.25$ per package and chips cost .50$. Luis bought 10 snacks how man

ale4655 [162]

Answer:

Luis bought 5 packages of candy and 5 bags of chips

Step-by-step explanation:

1.25 for candy

0.50 for chips

1.25c + 0.50c = 8.75

First I tried to see how many times I could multiply 1.25, the answer that made the most sense was 5 because not only is 5 + 5 = 10, but when it equals the amount of money. So I changed my equation:

1.25(5) + 0.5(5)

6.25 + 2.5 = 8.75

From a large number of actuarial exam scores, a random sample of scores is selected, and it is found that of these are passing s

Mnenie [13.5K]

<u>Supposing 60 out of 100 scores are passing scores</u>, the 95% confidence interval for the proportion of all scores that are passing is (0.5, 0.7).

The lower limit is 0.5.
The upper limit is 0.7.

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

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

In which

z is the z-score that has a p-value of $\frac{1+\alpha}{2}$ .

60 out of 100 scores are passing scores, hence $n = 100, \pi = \frac{60}{100} = 0.6$

95% confidence level

So $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so $z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6 - 1.96\sqrt{\frac{0.6(0.4)}{100}} = 0.5$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6 + 1.96\sqrt{\frac{0.6(0.4)}{100}} = 0.7$

The 95% confidence interval for the proportion of all scores that are passing is (0.5, 0.7).

The lower limit is 0.5.
The upper limit is 0.7.
