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

What number could replace kkk below? \dfrac{k}{100} = \dfrac{1}{10} 100 k ​ = 10 1 ​ start fraction, k, divided by, 100, end fra
Ivanshal [37]

Answer:

<h3>k = 10</h3>

Step-by-step explanation:

Given the equation;

\dfrac{k}{100} = \dfrac{1}{10}

We are to find the value of k.

Cross multiply;

\dfrac{k}{100} = \dfrac{1}{10} \\10 \times k = 100 \times 1\\10k = 100\\

Divide both sides by 10

10k/10 = 100/10\\k = 10

Hence the value of k is 10
