A company has calculated its running sum of forecast errors to be 500 and its mean absolute deviation is exactly 35. Which of th

Stella [2.4K]

Answer:

correct option is here B. About 14.3

Explanation:

given data

running sum of forecast errors RSFE = 500

mean absolute deviation MAD = 35

solution

we get here tracking signal that is express here as

tracking signal = $\frac{RSFE}{MAD}$ .................................1

put here value and we will get tracking signal

tracking signal = $\frac{500}{35}$

tracking signal = 14.3

so correct option is here B. About 14.3

You want to buy a new sports coupe for $84,500, and the finance office at the dealership has quoted you an apr of 6.6 percent fo

Margaret [11]

Answer: The monthly payment will be $2007.81.

We have:

Cost of the sports coupe (PV) $84,500

Annual Percentage Rate (APR) 6.6%

Loan tenure in months (n) 48

We can find the monthly payment by using the Present value of an annuity formula:

$\mathbf{PV_{Annuity}= PMT * \left ( \frac{1-(1+r)^{-n}}{r} \right )}$

Since APR is a yearly number, we need to convert it into a monthly rate.

So , $r = \frac{0.066}{12} = 0.0055$

Plugging values in the PV formula above we get,

$\mathbf{84500 = PMT * \left ( \frac{1-(1+0.0055)^{-48}}{0.0055} \right )}$

$\mathbf{84500 = PMT * \left ( \frac{1-0.768529253}{0.0055} \right )}$

$\mathbf{84500 = PMT * \left ( \frac{0.231470747}{0.0055} \right )}$

$\mathbf{84500 = PMT * 42.08559028}$

$\mathbf{\frac{84500}{42.08559028}= PMT}$

$\mathbf{PMT = 2007.813112}$

An investment has an expected return of 11 percent per year with a standard deviation of 26 percent. Assuming that the returns o

Keith_Richards [23]

Answer:

$P(X$

And we can find this probability using the normal standard distribution table or excel and we got:

$P(Z$

Explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:

$X \sim N(11,26)$

Where $\mu=11$ and $\sigma=26$

We are interested on this probability

$P(X$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(X$

And we can find this probability using the normal standard distribution table or excel and we got:

$P(Z$

What happened to anyone who could not keep up with the march?

miskamm [114]

The Nazi soldiers were given order to shoot anyone who could not keep up with the march. Those who escape shooting would probably be trampled upon by the moving multitude. <span />
