Which information security objective allows trusted entities to endorse information?

Serjik [45]

Certification information is the security objective that allows trusted entities to endorse information.

Certification information is what credits people to be certified in teaching information to other employees and allowing the information to be accredited. To make sure the information is given out properly and is trusted, accurate information we need to make sure its certified and verified.

You are saving for a Porsche Carrera Cabriolet, which currently sells for nearly half a million dollars. Your plan is to deposit

Firdavs [7]

Answer:

1. $486,134.86

2. $525,593.86

3. $602,492.04

Explanation:

You need to use the formula to calculate the future value of a constant annual deposit:

$Future\text{ }value=Deposit\times \bigg[\dfrac{(1+r)^n-1}{r}\bigg]$

Where r is the expected percent return, and n the number of years.

1. For a deposit of $30,800 at the end of each year for the next 11 years, with 7% interest.

You will have saved:

$Future\text{ }value=\$ 30,800\times \bigg[\dfrac{(1+0.07)^{11}-1}{0.07}\bigg]$

$Future\text{ }value=\$ 30,800\times 15.7835993=\$486,134.86$

2. For a deposit of $33,300 each year, for the same number of years and with the same interest rate.

You will have saved:

$Future\text{ }value=\$ 33,300\times \bigg[\dfrac{(1+0.07)^{11}-1}{0.07}\bigg]$

$Future\text{ }value=\$ 33,300\times 15.7835993=\$525,593.86$

3. For a deposit of $30,800 each year, but with 11 percent interest, for 11 years.

$Future\text{ }value=\$ 30,800\times \bigg[\dfrac{(1+0.11)^{11}-1}{0.11}\bigg]$

$Future\text{ }value=\$ 30,800\times 19.56143=\$602,492.04$

Of all customers purchasing automatic garage door openers, 75% purchase chain-driven model. Let X = the number among the next 15

KIM [24]

Answer:

$P(X=x)=C(15,x)\cdot(0.75)^x\cdot(0.25)^{(15-x)}$

Explanation:

The probability mass function (PMF), or frequency function, is the function that gives the probabilities that a discrete random variable take some values.

In this problem, it is requested the frequency function (PMF) for the number of purchasers, among the next 15, who select a chain-driven model.

Then , you need to find, the function that gives P(X=0), P(X=1), P(X=2), P(X=3), . . . up to P(X=15).

Such as any function, the frequency function can be presented as a formula, as a table, or as a graph.

Note that the statement represents a binomial disbribution in which success is that a customer select a chain-driven model and the fail is that a cusotmer does not select a chain-driven model.

The binomial probability for X = the number among the 15 purchasers who select the chain-driven model is given by the formula:

$P(X=x)=C(n,x)\cdot(p)^x\cdot(1-p)^{(n-x)}$
