Given the following probability distribution, what is the expected value of the random variable X? X P(X) 100 .10 150 .20 200 .3
Mekhanik [1.2K]

Answer:

d) 205

Step-by-step explanation:

<u><em>Step(i):-</em></u>

x             :   100      150      200      250      300

p(X=x)    :   0.10     0.20    0.30     0.30      0.10

<u>Step(ii):-</u>

Let 'X' be the discrete random variable

Expected value of the random variable

   E(X) = ∑ x P(X=x)

           =  100 X 0.10 + 150 X 0.20 + 200 X 0.30 +250 X 0.30 + 300 X 0.10

          =   205

<u>Final answer:</u>-

The expected value     E(X) = 205

Estimate 58% of 112 using benchmark percents. Explain your answer.
vitfil [10]

Answer:

64.96

Step-by-step explanation:

The most common benchmark percents are 0\% , 10\% , 25\% , 50\% , 75\% and 100\%

We are given 58\% which is closest to 50\%.

Now we calculate 50\% \ of \ 112 which is equal to 56.

We are left with 8\% more to add.

We can say 1\% \ of \ 112 \ is\ 1.12

Therefore 8\% \ of \ 112 \ would \ be \ 1.12\times8=8.96

Now add the two.

56+8.96= 64.96

Thus 64.96 is the answer.
