The number in between the bars will always be equal to the same number, but positive. For example:
|-15| = 15

|15| = 15

|5| = 5

|-5| = 5

At age 23, someone sets up an IRA (individual retirement account) with an APR of 7%. At the end of each month he deposits $

MAVERICK [17]

Answer:

The ira will contain $228,278.05 when he retires at age 65. This is 6.04 times the amount of money he deposited.

Step-by-step explanation:

In order to solve this problem, we can make use of the following formula:

$FV=PMT[\frac{(1+i)^{n}-1}{i}]$

Where:

FV= Future value of the ira

PMT= the amount of money you deposit each month

i= is the interest rate per period

n=number of periods

in this case we will assume the interest will be compounded each month.

So:

FV this is what we need to know.

PMT= $75 the amount he will deposit each month

t = 42 years,

this is 65-23=42

n=42 years * 12 months/year = 504 months

i=0.07/12

So we can now use the given formula:

$FV=PMT[\frac{(1+i)^{n}-1}{i}]$

$FV=75[\frac{(1+\frac{0.07}{12})^{504}-1}{\frac{0.07}{12}}]$

So we get:

FV=$228,278.05

which is the amount of money he will have after 42 years.

In total, he deposited:

$75*504months = $37,800

so he will have:

$\frac{228,278.05}{37,800}=6.04$ times the amount of money he deposited throughout this time.

Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable

Alex_Xolod [135]

Answer:

a) Discrete, because the number of point scored during basket ball is countable.

For instance, the amount of point scored in a basketball could be 75, 103, 63 etc. The numbers are countable

b) Continuous, because the amounts of rainfall is a random variable that is uncountable.

For instance, the amount of rainfall in City Upper B during April could be 0.10 inches of rain per hour, 0.30 inches of rain per hour. This numbers are not countable, they are rather approximated or rounded off.

Step-by-step explanation:

A random variable is considered discrete if its possible values are countable while a random variable is considered to be continuous if it's possible values are not countable.

−(−2−5x)+(−2)=18 solve for x

lisov135 [29]

PEMDAS: distribute the negative to (-2-5x) so it becomes (2+5x)+(-2)=18

Add 2 to both sides: 2+5x=20

Subtract 2: 5x=18

Divide 5: x= 18/5
