Answer:

$144,843.5

Step-by-step explanation:

In this problem we are going to apply the compound interest formula

A= P(1+r)^t

A = final amount

P = initial principal balance

r = interest rate

t = number of time periods elapsed

Given data

P= $27,000

R= 7.25%= 7.25/100= 0.0725

T= 24

A=27000(1+0.0725)^24

A= 27000(1.0725)^24

A= 27000*5.364

A= $144,843.5

In 24 years her account balance will be $144,843.5

Answer:

According to the information of the problem x = 15 , p=2.90 and dp/dt = -1.15

then $\frac{dx}{dt} = -3.357\\$

Step-by-step explanation:

Since everything is changing with respect to time and $p,x$ are related according to the following equation

$5p+5x+3px = 71$

We need to find the implicit derivative with respect to the time. And we get the following.

$5\frac{dp}{dt}+5\frac{dx}{dt}+3x\frac{dp}{dt}+3p\frac{dx}{dt} = 0$

$\frac{dx}{dt}$ is what we don't know, so we solve for it and get

$\frac{dx}{dt} = - (5\frac{dp}{dt}-3x\frac{dp}{dt})/ (5+3p)$

Now. According to the information of the problem x = 15 , p=2.90 and dp/dt = -1.15

then $\frac{dx}{dt} = -3.357\\$

4 percent of all cars produced on a Monday are deficient, while 3 percent of Friday's production is deficient; on all other days

neonofarm [45]

Answer:

Let the total numbers of cars be ten then the total cars produced in one week would be 50

Probability of deficient cars on Monday = 4/10

Probability of deficient cars on Tuesday =1/10

Probability of deficient cars on Wednesday = 1/10

Probability of deficient cars on Thursday = 1/10

Probability of deficient cars on Friday = 3/10

Probability ( deficient car)= 10/50 or 1/5

Probability that it produced on Monday 4/10*1/5= 4/50= 2/25= 8/100= 0.08 or 8%

Probability of deficient cars on Monday = 4/10* 12/100= 48/1000= 0.048or 4.8%

Probability of deficient cars on Tuesday =1/10 *22/100= 22/1000= 0.022 or 2.2%

Probability of deficient cars on Wednesday = 1/10*22/100=22/1000= 0.022 or 2.2%

Probability of deficient cars on Thursday = 1/10*22/100=22/1000= 0.022 or 2.2%

Probability of deficient cars on Friday = 3/10*22/100= 66/1000= 0.066 or 6.6%

Answer:

You have the formula wrong.

The volume of a cylinder = PI * radius^2 * height

To find the height, the formula is:

height = volume / (PI*radius^2)

I'm assuming the radius = .6 meters so

height = 720 / (3.14159265 * .6^2)

height = 720 / 1.130973354

height = 636.61977 meters
