A new car is purchased for 20000 dollars. The value of the car depreciates at 12. 5% per year. What will the value of the car be

Georgia [21]

To solve the problem we need to know about depreciation.

<h2>Formula of Depreciation</h2>

The formula of depreciation is given as,

$A = P(1-r)^t$

where,

A is the value of an object after t years of time,

P is the value of the object at the beginning, and

r is the rate of depreciation.

The value of the car after 11 years is $4,603.81.

<h2>Explanation</h2>

Given to us

Cost of Car at the beginning, p = $20,000
Rate of depreciation, r = 12.5%
Time, t = 11 years

<h3>Value of the car after 11 years</h3>

Substituting the values in the formula of depreciation,

$A = P(1-r)^t$

Value of the car after 11 years = $P(1-r)^n$

$= \$20,000(1-0.125)^{11}\\\\
= \$20,000\times 0.23\\\\
= \$4,603.822 \approx \$4,603.81$

Hence, the value of the car after 11 years is $4,603.81.

Mrrafil [7]

16x

Step-by-step explanation:

6 increased by 2 --> 6+2

difference of 4 and 2 --> 4-2

first part times the second part --> 6 + 2 (4-2)

times a number --> • x

put it all together --> (6+2)(4-2) • x or 16x

A health statistics agency in a certain country tracks the number of adults who have health insurance. Suppose according to the

Fynjy0 [20]

Answer:

a) 15.4% probability that a randomly selected person in this country is 65 or older

b) 0.023 = 2.3% probability that the person is 65 or older

Step-by-step explanation:

To solve b), i will use the Bayes Theorem.

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

(a) What is the probability that a randomly selected person in this country is 65 or older?

22.7% of people in the county are under age 18

61.9% are ages 18–64

p% are 65 or older.

The sum of those is 100%. So

22.7 + 61.9 + p = 100

p = 100 - (22.7+61.9)

p = 15.4

15.4% probability that a randomly selected person in this country is 65 or older.

(b) Given that a person in this country is uninsured, what is the probability that the person is 65 or older?

Event A: Uninsured

Event B: 65 or older.

15.4% probability that a randomly selected person in this country is 65 or older.

This means that $P(B) = 0.154$

1.4% of those 65 and older do not have health insurance.

This means that $P(A|B) = 0.014$

Probability of not having insurance.

22.7% are under 18. Of those, 5.4% do not have insurance.

61.9% are aged 18-64. Of those, 12.8% do not have insurance.

15.4% are 65 or over. Of those, 1.4% do not have health insurance. So

$P(A) = 0.227*0.054 + 0.619*0.128 + 0.154*0.014 = 0.093646$

Then

$P(B|A) = \frac{0.154*0.014}{0.093646} = 0.023$

0.023 = 2.3% probability that the person is 65 or older
