Frank invests $1,000 in simple interest investment account that pays 8% a year. After a number of years, he withdraws his balanc

IceJOKER [234]

Answer:

$15\ years$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

A is the Final Investment Value

I is the amount of money in Interest

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\ years\\ P=\$1,000\\ A=\$2,200\\r=0.08$

<em>Find the interest I</em>

$I=A-P=\$2,200-\$1,000=\$1,200$

substitute in the formula above

$\$1,200=\$1,000(0.08t)$

Solve for t

$t=1.2/0.08=15\ years$

Two cars started from the same point and traveled on a straight course in opposite directions for exactly 2 hours, at which time

OlgaM077 [116]

Answer with Step-by-step explanation:

Let speed of one car=x miles/h

Speed of second car=x+8 mi/h

Time,t=2 hours

Distance between two cars=208 miles

We have to find the average speed for each car for 2-hour trip.

Distance= $Speed\times time$

Distance traveled by one car=2x

Distance traveled by second car=2(x+8)

According to question

$2x+2(x+8)=208$

$2x+2x+16=208$

$4x=208-16$

$4x=192$

$x=\frac{192}{4}=48$

Speed of one car=48mph

Speed of second car=48+8=56mph

The average daily rainfall in Seattle for the month of June has a mean absolute deviation of 1.3 inches. What conclusion can you

Oduvanchick [21]

Using the mean absolute deviation, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.

<h3>What is the mean absolute deviation of a data-set?</h3>

The mean of a data-set is given by the sum of all observations divided by the number of observations.

The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.

The mean absolute deviation represents the average by which the values differ from the mean.

In this problem, the mean absolute deviation is of 1.3 inches, hence, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.
