Answer:

a) 3.375 cents

b) 26 Apples

Step-by-step explanation:

a) Each apple costs .1875 cents, multiply .1875 by 18 to get the cost of 18 apples

b) divide 5 by .1875 to get your 26.6666667 Apples, which would round down because you can't have .6666667 of an apple

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p

strojnjashka [21]

Answer:

P(X = 3) = 0.14680064

Step-by-step explanation:

Formula=============================

$p\left( X=k\right) =C^{k}_{n}p^{k}(1-p)^{n-k}\ \ ;\ k\in \left\{ 0,\ldots ,n\right\}$

……………………………………………………………………..

Given :

n = 8

p = 0.2

1 - p = 1 - 0.2 = 0.8

k = 3

Then

$p\left( X=3\right) =C^{3}_{8}(0.2)^{3}(0.8)^{5}$

$=0.14680064$

A geometric sequence can be used to describe the population of rabbits on a

vlabodo [156]

Answer:

step 1

Find the average growth per year of the populations of rabbits farm A

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=40

average=[40-5]/2---------> 17.5

step 2

Find the average growth per year of the populations of rabbits farm B

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=30

average=[30-5]/2---------> 12.5

step 3

Compare the average growth per year of the populations of rabbits on both farms

farm A=17.5

farm B=12.5

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.

therefore

the answer is the option C)

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.
