Tomás bought a new car for $41,000. If the value of the car depreciates by 17% each year, determine the value

This is a means of reducing the cost of a goods or an asset over time. The value of the car after 9 years is approximately $888

<h3>Depreciation</h3>

This is a means of reducing the cost of a goods or an asset over time.

Mathematically, the cost of goods after a particular year is expressed as:

P(t) = P0e^-rt

Given

P0 = $41000
rate r = 17% = 0.17
time t = 9 years

Substitute

P(17) = 41000r^0.17(9)
P(17) = 4100(0.21653)

P(17) = 887.79

Hence the value of the car after 9 years is approximately $888

Answer:

(a) Hypergeometric distribution

(b) 0.785384...

Step-by-step explanation:

(a) looking at the question, we see that $X = \in \{0, ... , 10 \}$ , suppose Evans studied s key terms, this implies that he has not studied 100 - s key terms. Suppose $k = \in \{0, ... , 10 \}$ if X = k, then k out of the s key terms he had studied appeared. But 10 - k out of 100 - s key terms he hasn't studied appeared. Thus X is an Hypergeometric distribution, X~HGeom(s, 100 - s, 10) with PMF:
