4 0

Answer:

0.84

Step-by-step explanation:

From the given histogram we can state that

  • P(x=1)=0.32;
  • P(x=2)=0.24;
  • P(x=3)=0.28;
  • P(x=4)=0.16.

Note that the probability

P(1\le x\le 3)=P(x=1)+P(x=2)+P(x=3)=0.32+0.24+0.28=0.84.

Fernando purchased a new motorhome for $180,000, but the motorhome will depreciate
Dmitry_Shevchenko [17]

Your answer would be 122,400.

<em>To solve, follow these steps!! </em>First let's start with the price of the motorhome, 180,000. If it <em>depreciates, </em>that means it's going to lose value ever year.

It will depreciate 4% every year, so we need to find 4% of 180,000. You can just plug this into a calculator and get 7,200.

Next, it will depreciate for 8 years, so we multiply 7,200 x 8 and get 57,600. Lastly, we will subtract this from 180,000 and get 122,400.
