Answer:

B) 4.5

Step-by-step explanation:

The area of the first figure is 10x

The area of the second figure is 6(x+3)=6x+18

To solve, find the x that makes 10x=6x+18

   1) 10x=6x+18

   2) 4x=18

   3) x=4.5

To check work)

   1) 10(4.5)=6(4.5)+18

   2) 45=27+18

   3) 45=45

For a group of 100 people, compute(a) the expected number of days of the year that are birthdays of exactly 3 people.(b) the exp
Scilla [17]

Answer:

Step-by-step explanation:

Leaving leap years, a year contains 365 days.

For a group of 100 people, each person is independent of the other and probability of any day being his birthday has a chance of

\frac{1}{365}

a) Probability that  exactly 3 people have same birthday = \frac{1}{365^3}

Each day is independent of the other

And hence no of days having exactly 3 persons birthday out of 100 persons is binomial with n = 365 and p = \frac{1}{365^3}

Expected value of days = np = \frac{1}{365^2}

b) Distinct birthdays is binomail with p =1/365 and n = 365

Hence

expected value = np =1
