I believe it’s 5. This is because when doing 5X3=15 and then 15+7=22 then solving for the other one and doing 5X2=10 and then doing 10+12=22. This shows that 5 is correct because you’re getting the same value for the solution. Hope this helps:)

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

Alexa pays 7/20 of a dollar for each minute she uses her pay-as-you-go phone for a call, and 2/5 of a dollar for each minute of
9966 [12]

Answer:

  • The system of equations is x + y = 85 and 7/20x+2/5y=31
  • To eliminate the x-variable from the equations, you can multiply the equation with the fractions by 20 and multiply the other equation by -7.
  • B-She used 60 minutes for calling and 25 minutes for data.

Step-by-step explanation:

It is always a good idea to start by defining variables in such a problem. Here, we can let x represent the number of calling minutes, and y represent the number of data minutes. The the total number of minutes used is ...

  x + y = 85

The total of charges is the sum of the products of charge per minute and minutes used:

  7/20x + 2/5y = 31.00

We can eliminate the x-variable in these equations by multiplying the first by -7 and the second by 20, then adding the result.

  -7(x +y) +20(7/20x +2/5y) = -7(85) +20(31)

  -7x -7y +7x +8y = -595 +620 . . . . eliminate parentheses

  y = 25 . . . . . . . . simplify

Then the value of x is

  x = 85 -y = 85 -25

  x = 60

How many times is 1 trillion greater than 1 billion
vodomira [7]

1 trillion can be written as 1,000,000,000,000

1 billion can be written as 1,000,000,000

There are 3 more 0’s in 1 trillion than there are in 1 billion, so therefore 1 trillion is 1,000 times greater than 1 billion.

If you have any further questions feel free to ask.

Hope this helps
