For one pair of socks you pay $12 plus $2 shipping.

Let's use x as the variable for how many pairs of socks someone might buy.

If someone buys 5 pairs of socks, they will pay $62. $12 * 5 + $2

So, we can write the expression as 12x + 2.

Suppose we are interested in bidding on a piece of land and we know one other bidder is interested.1 The seller announced that t

Usimov [2.4K]

Answer:

0.4

Step-by-step explanation:

Given:-

- The uniform distribution parameters are as follows:

a = $10,000 b = $15,000

Find:-

Suppose you bid $12,000. What is the probability that your bid will be accepted?

Solution:-

- We will denote a random variable X that defines the bid placed being accepted. The variable X follows a uniform distribution with parameters [a,b].

X ~ U(10,000 , 15,000)

- The probability of $12,000 bid being accepted can be determined by the cdf function of the uniform distribution, while the pmf is as follows:

Pmf = 1 / ( b - a )

Pmf = 1 / ( 15,000 - 10,000 )

Pmf = 1 / ( 5,000 )

$cdf = \int\limits^x_a {\frac{1}{5000} } \, dy \\\\cdf = {\frac{y}{5000} }\limits^x_a \\\\P(X$
