Answer:

Step-by-step explanation:

Simply substitute the x and y values into the equation, Infinity is a number that gets closer & closer to zero and the y-intercept is always 2.

Infinity is a number that gets closer & closer to zero and the y-intercept is always 2.

y=-2(2)(-infity)+2

y=2

Well to find the volume of a pyramid, you take the base (12mm) times the height (15mm) times 1/3 to get an answer of 60mm squared.

Hope this helped.

A random sample of 60 suspension helmets used by motorcycle riders and automobile race-car drivers was subjected to an impact te

pentagon [3]

Answer:

The 95% confidence interval on the true proportion of helmets of this type that would show damage from this test is (0.169, 0.397).

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

For this problem, we have that:

$n = 60, \pi = \frac{17}{60} = 0.283$

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 $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.283 - 1.96\sqrt{\frac{0.283*0.717}{60}} = 0.169$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.283 + 1.96\sqrt{\frac{0.283*0.717}{60}} = 0.397$

The 95% confidence interval on the true proportion of helmets of this type that would show damage from this test is (0.169, 0.397).

Solve the following dividend problem.

brilliants [131]

To get dividend per share, we need to divide total dividend by total numbers of shares outstanding.

Dividend per share = $\frac{40,000}{50,000}=0.8$ dollars.

Since per share you get $0.8, for 100 shares you will get $0.8*100=80$ dollars.

Also, that is $\frac{80}{40,000}*100=0.2$ percent of the total dividends.

ANSWER:

A. $0.8 per share

B. $80 (and that is 0.2% of total dividend)

A warehouse distributor of carpet faces a normally distributed demand for its carpet. The average demand for carpet from the sto

dimulka [17.4K]

Answer:

There is a 25.14% probability that the order will not be met during a month.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 4500, \sigma = 900$ .
