Answer:
(a) The value of P (X = 2) is 0.3571.
(b) The value of P (X ≤ 1) is 0.5952.
Step-by-step explanation:
A Hypergeometric distribution is used to describe the probability distribution of <em>x</em> successes in <em>n</em> random draws from a population of size <em>N </em>that contains exactly <em>r</em> items that are considered as success. In this distribution each draw results in either a success or a failure.
The probability mass function of Hypergeometric distribution is:
Given:
N = 9
r = 3
n = 4
(a)
Compute the value of P (X = 2) as follows:
Thus, the value of P (X = 2) is 0.3571.
(b)
Compute the value of P (X ≤ 1) as follows:
P (X ≤ 1) = P (X = 0) + P (X = 1)
Thus, the value of P (X ≤ 1) is 0.5952.
Let <em>x</em> = 0.424242... . Then 100<em>x</em> = 42.424242... . So we can write
100<em>x</em> - <em>x</em> = 99<em>x</em> = 42.424242... - 0.424242... = 42
which means
<em>x</em> = 42/99 = 14/33
and so
11.424242... = 11 + 14/33 = 377/33
We can set this geometric sequence up as so:
y = 50,000(0.90)^(x - 1)
The value of the car is represented by y, and the year is represented by x.
Answer:
A "rational expression" is a polynomial fraction, and anything you could do with ... need to evaluate the expression, and it can be useful to know which values would ... x2 + 4 = 0 x2 = –4. This has no solution, so the denominator is never zero.
