There are 185 deer in a state park. The population is increasing at the rate of 16% per year. Enter a

stich3 [128]

Answer:

Approximately 3.4 years more or less

Step-by-step explanation:

If we represent this exponential growth as P=185(1.16)^n where n is the number of years passed and P is the population, then:

P=185(1.16)^n

305=185(1.16)^n

1.65=1.16^n

log₁.₁₆(1.65)=log₁.₁₆(1.16^n)

3.37=n

So the deer population will reach 305 in approximately 3.4 years.

The diagram below shows a wall with a

yulyashka [42]

Answer: H (131.125 ft^2)

Step-by-step explanation:

first, you need to find the area of the wall

wall:

A=Lw (length times width)

A= 9.75 x 15.5 (I changed them into decimals)

A = 151.125

now you need to find the area of the window

window:

A = Lw

A = 4 x 5

A = 20

now you need to subtract the area of the window from the area of the wall to find the amount of space you need to cover with wallpaper

151.125 - 20 = 131.125

In a group of 40 people, 35% have never been abroad. Two people are selected at random without replacement and are asked about t

Alisiya [41]

Answer:

$\frac{7}{60}$

Step-by-step explanation:

Given that in a group of 40 people, 35% have never been abroad. Two people are selected at random without replacement and are asked about their past travel experience.

Since the two are drawn without replacement the first trial affects the second trial. In other words, each trial is not independent of the other.

a) Hence this cannot be binomial experiment. The reason is p=probability for each trial is not constant as first draw affect the probability for Ii draw

b) The probability that in a random sample of 2, no one has been abroad

=Prob of selecting both people from the group where no one has been abroad

We have in the group 35% i.e. 14 people never been to abroad

So required probability = Prob of selecting both from 14 people

= $\frac{14C2}{40C2} \\=\frac{14*13}{40*39} \\=\frac{7}{60}$
