The table below shows the amount of a radioactive compound remaining after X years Sarah is compiling the data into a lab report
Murrr4er [49]

Answer:

  A. the y-intercept of the graph is 900, and as X increases, f(x) approaches 100.

Step-by-step explanation:

The table can be described by the function ...

  f(x) = 100 +800·2^-x

This is an exponential decay (not a constant-rate decay) from a y-intercept of 900 down to a minimum value of 100 (not zero).

The best description is that of choice A.

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

Handsome jack is buying a pony mad of diamonds. The price of the pony is p dollars and jack also has pay 25% diamond pony tax. H
Leona [35]

Answer:

5/4 P dollars

Step-by-step explanation:

Given that,

price of pony =  P

Tax which is to added in the total price of pony = 25% of pony price

so, now total price of pony including its tax = P + 25%P

                                                                        =  P + 25/100 P

                                                                        =  P + 1/4 P

                                                                        = 5/4 P dollars

                                                                        =  1.25 P dollars
