Answer:

28.5$ yen

Step-by-step explanation:

If the foreign exchange rate between the U.S. dollar and the Japanese yen is 1:90, then you will multiply it by the amount that you are trying to turn in. So in this case you will be multiplying 1:90 by 15 to get your yen. hope that helps thx :)

Suppose that the epidemiologist wants to re-estimate the population proportion and wishes for her 95% confidence interval to hav

Svetllana [295]

Answer:

She needs a sample of at least 385.

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 $1 - \frac{\alpha}{2}$ .

The margin of error is:

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

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

How large a sample should she take to achieve this?

She needs a sample of size at least n.

n is found when M = 0.04.

We do not know the true population proportion, so we use $\pi = 0.5$ , which is the case for which we are going to need the largest sample size.

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

$0.05 = 1.96\sqrt{\frac{0.5*0.5}{n}}$

$0.05\sqrt{n} = 1.96*0.5$

Dividing both sides by 0.05

$\sqrt{n} = 19.6$

$(\sqrt{n})^{2} = 19.6^{2}$

$n = 384.2$

Rounding up

She needs a sample of at least 385.

miles= 30 × hours

use this equation to fill out the graph and find out what y (miles traveled) equals.

for example, multiply 5 (the hours passed) by 30. Your answer would be 150, which is the miles the biker would travel in 5 hours.

Make a conjecture. What properties do you think stay the same after a translation? Check all that apply. angle measures length o

Andrews [41]

I would check all of these answers because basically, when performing a translation, you are simply moving the shape around. It is not being stretched or manipulated in shape so the angle measures, length, shape, and size would not change. Also, a translation does not rotate the object, so the orientation would not change either. :)

What is the length of MN

NNADVOKAT [17]

Answer:

value of x = 5

Step-by-step explanation:

Given:

∠L = ∠n

So,

ML = MN

So,

3x = x + 10

2x = 10

x = 5

value of x = 5
