Answer:2 > x

Step-by-step explanation:

Solve for x. Pretend the “>” sign is no Different than an “=“ Sign.

8>2x+4

Subtract 4 from both sides of the equation

(8-4)>2x+4-4

4>2x

Divide both sides of the equation by 2 to isolate the variable of x.

2>x

Before we use an applet to simulate the selection of random samples from this population, let’s make sure we are clear about who
Sauron [17]

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

<u>Explanation</u>:-

<u>Introduction</u>:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

<u>Example</u>:-

  • when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.
  • If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be <u>small, large but finite or infinite.</u>

<u> Example :- 1</u>

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are <u>finite number</u> of observations.

<u>Example :- 2</u>

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

<u>Population</u>:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the<u> population</u>

The number of observations in the population is defined to be the size of the population.

<u>Example</u> :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

<u>Sample</u>:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population

The Department of Agriculture is monitoring the spread of mice by placing 100 mice at the start of the project. The population,
uranmaximum [27]

Answer:

Step-by-step explanation:

Assuming that the differential equation is

\frac{dP}{dt} = 0.04P\left(1-\frac{P}{500}\right).

We need to solve it and obtain an expression for P(t) in order to complete the exercise.

First of all, this is an example of the logistic equation, which has the general form

\frac{dP}{dt} = kP\left(1-\frac{P}{K}\right).

In order to make the calculation easier we are going to solve the general equation, and later substitute the values of the constants, notice that k=0.04 and K=500 and the initial condition P(0)=100.

Notice that this equation is separable, then

\frac{dP}{P(1-P/K)} = kdt.

Now, intagrating in both sides of the equation

\int\frac{dP}{P(1-P/K)} = \int kdt = kt +C.

In order to calculate the integral in the left hand side we make a partial fraction decomposition:

\frac{1}{P(1-P/K)} = \frac{1}{P} - \frac{1}{K-P}.

So,

\int\frac{dP}{P(1-P/K)} = \ln|P| - \ln|K-P| = \ln\left| \frac{P}{K-P} \right| = -\ln\left| \frac{K-P}{P} \right|.

We have obtained that:

-\ln\left| \frac{K-P}{P}\right| = kt +C

which is equivalent to

\ln\left| \frac{K-P}{P}\right|= -kt -C

Taking exponentials in both hands:

\left| \frac{K-P}{P}\right| = e^{-kt -C}

Hence,

\frac{K-P(t)}{P(t)} = Ae^{-kt}.

The next step is to substitute the given values in the statement of the problem:

\frac{500-P(t)}{P(t)} = Ae^{-0.04t}.

We calculate the value of A using the initial condition P(0)=100, substituting t=0:

\frac{500-100}{100} = A} and A=4.

So,

\frac{500-P(t)}{P(t)} = 4e^{-0.04t}.

Finally, as we want the value of t such that P(t)=200, we substitute this last value into the above equation. Thus,

\frac{500-200}{200} = 4e^{-0.04t}.

This is equivalent to \frac{3}{8} = e^{-0.04t}. Taking logarithms we get \ln\frac{3}{8} = -0.04t. Then,

t = \frac{\ln\frac{3}{8}}{-0.04} \approx 24.520731325.

So, the population of rats will be 200 after 25 months.

How do you find the radius of a circle with a circumference of 12pi
sergejj [24]

Answer:

6

Step-by-step explanation:

The circumference of a circle is 2\pir\pi r, so 12\pi=2\pi r\\12=2r\\r=6.  We can use this because the area of a circle is \pi r^2.  Thus, \pi*6^2=36\pi.
