Whole numbers are numbers without decimal points greater than 0.

The set of whole numbers is:

$W =\{0,1,2,3,4.....\}$

In the introductory part of this solution, I stated that:

Whole numbers do not have decimal point
The smallest whole number is 0

This means that the following numbers are whole numbers:

1, 9, 10, 67

While the following numbers are not:

-1, 9.0, 1.0, -67

Let W be the set of whole numbers; the set is:

$W =\{0,1,2,3,4.....\}$

The dots after 4 means the set still continues

A polling organization contacts 1172 male university graduates who have a white collar job and asks whether or not they had rece

hichkok12 [17]

Answer:

The population in the study are those male university graduates who have a white collar job.

Step-by-step explanation:

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

For example:

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.

In this problem, we have that:

Sample of 1172 male university graduates who have a white collar job and asks whether or not they had received a raise atnbsp work nbspduring the past 4 months.

What is the population in the study?

The sample is of male university graduates who have a white collar job.

So the population in the study are those male university graduates who have a white collar job.

The population of Centerville increases each year. The function C(t) = P(1 +r)^t represents the population of centerville at yea

strojnjashka [21]

Answer:

P represents the population in year 0 ⇒ D

Step-by-step explanation:

* Lets explain the exponential growth function

- The exponential growth function is f(x) = a (1 + r)^t, where a is the initial

amount (at t = 0), (1 + r) is the factor of growth , r is the rate of growth

in decimal ant is the time of growth

* Lets solve the problem

∵ The function C(t) = P(1 + r)^t represents the population of

centerville at year t, where P is the initial population and r is the

rate of increase

- Ex: If your investment is increased 10% annually, then that means

each year, your total has multiplied itself by 110% (the growth factor

is 1 + 10/100 = 1.1)

∴ (1 + r) is the factor grows each year

∵ C(t) = P(1 + r)^t

∴ C depends on P(starting population) , r(the increasing rate and

t(the time in year)

∵ r is the rate of increase means the percentage of increasing , then

0 < r < 1

∴ r is not less than 0

∵ P is the initial amount when t = 0

∴ P represents the population in year 0

Write each expression below in radical form and compute the value without using a calculator.

gregori [183]

Assuming that an exponentiation sign is missing, all you need to know is that rational exponents work like this:

$a^{\frac{b}{c}}=\sqrt[c]{a^b}$

So, you have

$25^{\frac{5}{2}}=\sqrt{25^5}=\sqrt{(5^2)^5}=5^5$

And similarly,

$81^{\frac{7}{4}}=\sqrt[4]{25^7}=\sqrt[4]{(3^4)^7}=3^7$
