You recently discovered that your job provides a 25% matching towards your retirement.

Harman [31]

Answer:

What is typed in the attached Excel file is =FV(B4,B5,-B3,0,0).

Step-by-step explanation:

Note: See the attached excel file for the calculation of future value of an ordinary annuity.

Since we want to find the balance after 30 years, the function in the Excel is the FV function which is used to calculate the future value (FV) of an ordinary annuity as follows:

=FV(rate,nper,-pmt,0,0) …………………… (1)

rate = Monthly interest rate = APR / 12 = 8.99% / 12 = 0.0899 / 12 = 0.00749166666666667. Note: This is typed in cell B4 in attached excel file.

nper = periods = number of months = 30 years * 12 months = 360. Note: This is typed in cell B5 in attached excel file.

pmt = monthly payment = $300. Note: This is typed in cell B3 in the attached excel file. And also typed as a negative value in cell B7, i.e. as -B3.

pv = present value = 0. Note: This is the first 0 typed in cell B7 in the attached excel file.

type 0 = 0 this is typed to indicate that deposit is made at end of period as a regular or ordinary annuity. This is the second 0 typed in cell B7 in the attached excel file.

Based on the above, the FV function in equation (1) above is converted to the following which is typed in the attached Excel file to find the balance after 30 years:

=FV(B4,B5,-B3,0,0)

The above then gives a future value of $548,080.11 which is the balance after 30 years.

135% as a fraction or a mixed number fully simplified please

solong [7]

Answer:

135% = 27/20 = 17/20 as a fraction

Step-by-step explanation:

Step 1: Write down the percent divided by 100 like this:

135% = 135/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As 135 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(135,100) = 5. So,

(135÷5)/(100÷5) = 27/20 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 135/100 is also equal to 1 7/20 when expressed as a mixed number.

Let v be the event that a computer contains a virus, and let w be the event that a computer contains a worm. suppose p(v ) = 0.1

ladessa [460]

We have been given that the probability of a computer containing a virus P(v) is 0.15 and probability of computer containing a worm P(w) is 0.05.

We are also told that probability of computer containing either virus or worm $P(v\cup w)$ is 0.17.

(a) To find out the probability that the computer contains both a virus and a worm we will use probability formula,

$P(A)+P(B)=P(A\cup B)+P(A\cap B)$

Now let us substitute our given values in this formula.

$0.15+0.05=0.17+P(A\cap B)$

$P(A\cap B)=0.20-0.17=0.03$

Therefore, probability that that the computer contains both a virus and a worm is 0.03.

(b) To find out the probability that the computer contains neither a virus nor a worm we will subtract the probability of computer containing both virus and worm from 1.

$\text{Probability that computer contains neither virus nor worm}=1-P(v\cup w)\\$

$=1-0.17=0.83$

Therefore, probability that the computer contains neither a virus nor a worm is 0.83.

What is the inverse of the function f(x) = x +3?

lana66690 [7]

Answer:

The inverse is x-3

Step-by-step explanation:

y = x+3

To find the inverse, exchange x and y

x = y+3

Solve for y

x-3 = y+3-3

x-3 =y

The inverse is x-3
