Answer:

  • D. $103800

Step-by-step explanation:

<u>Initial value of house:</u>

  • $184000

<u>Yearly increase rate of value:</u>

  • 3.5%

<u>Time </u>

  • 13 years

Since the increase is concerning the current price it would be exponential growth.

<u>The function would be:</u>

  • V(t) = 184000*(1 + 3.5/100)^t, where V is the value after t years

<u>For t= 13 we get:</u>

  • V(13) = 184000*(1.035)^13 = 287800

<u>Profit made would be:</u>

  • 287800 - 184000 = 103800

Correct option is D.

Answer:

Cost of Tammy's house =$184000

Rate of interest = 3.5% per annum

After 13years price will be

P(t) = 184000 {(1 +  \frac{3.5}{100}) }^{t} \\ P(t) =  184000 {(1 + 0.035)}^{t} \\ P(13) = 18400 {(1.035)}^{13}   \\ P(13) =\$ 287768

Total profit= $(287767-184000)= $103768

<h2>D. $103800 is the right answer.</h2>

Please help my mom is gonna hit me if i don't get it right. <br> the answer is NOT 18
Nookie1986 [14]

Answer:

Lol I hope she didn't hit you yet. The answer is x=14 :)

Step-by-step explanation:

So the first thing that you would want to do is find what 9 is multiplied by to get 21. To do this, we can just do a simple algebraic equation: 9x=21. The answer is 7/3 because mAgIc. So now, we can also multiply 6 by 7/3. this would be 42/3 because of more MaGiC. 42/3 divides into 14 because im  just obviously a mage. lol I hope this helped.

Explain why P(A|D) and P(D|A) from the table below are not equal. A 4-column table has 3 rows. The first column has entries A, B
dangina [55]

Answer:

P(A|D) and P(D|A) from the table above are not equal because P(A|D) = \frac{2}{10} and P(D|A) = \frac{2}{8}

Step-by-step explanation:

Conditional probability is the probability of one event occurring  with some relationship to one or more other events

.

P(A|D) is called the "Conditional Probability" of A given D

P(D|A) is called the "Conditional Probability" of D given A

The formula for conditional probability of P(A|D) = P(D∩A)/P(D)

The formula for conditional probability of P(D|A) = P(A∩D)/P(A)

The table

               ↓         ↓       ↓

            :  C     :   D    : Total

→ A      :  6     :    2    :   8

→ B      :  1      :    8    :   9

→Total :  7     :    10  :  17

∵ P(A|D) = P(D∩A)/P(D)

∵ P(D∩A) = 2 ⇒ the common of D and A

- P(D) means total of column D

∵ P(D) = 10

∴ P(A|D) = \frac{2}{10}

∵ P(D|A) = P(A∩D)/P(A)

∵ P(A∩D) = 2 ⇒ the common of A and D

- P(A) means total of row A

∵ P(A) = 8

∴ P(D|A) = \frac{2}{8}

∵ P(A|D) = \frac{2}{10}

∵ P(D|A) = \frac{2}{8}

∵  \frac{2}{10} ≠  \frac{2}{8}

∴ P(A|D) and P(D|A) from the table above are not equal
