In a particular region of a national park, there are currently 330 deer, and the population is increasing at an annual rate of 1
Afina-wow [57]

Answer:

a) P(t) = 330 (1.11)^{t}

b)P(t) →population after t years.

   t →number of years.

c) Number of deer after five years = 556

Step-by-step explanation:

a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.

So, we can use the formula

                             P(t) = P (1+\frac{r}{100} )^{t}

                             P(t) = 330 (1+\frac{11}{100} )^{t}

                             P(t) = 330 (1.11)^{t}

b) In this model

                        P(t) → population after t years

                          P → present population

                          r → annual increasing rate

c) Number of population after 5 years is,

                    P(5) = 330 (1.11)^{5}

                           = 556

 Number of deer after 5 years = 556

Dan rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 3.
agasfer [191]

Answer:

1 / 36

Step-by-step explanation:

A roll of 2 fair dice :

Total number of possible outcomes = n² ; n = number of faces in a dice = 6² = 36

Probability = required outcome / Total possible outcomes

Required outcome = total less than 3 = 1 (from sample space provided)

Hence,

P(total less than 3) = 1/36
