Answer: Cluster Sampling

Step-by-step explanation: I just took this test and got it correct :)

If the researchers choose three freshmen seminar classes at random and poll every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.

In the probability sampling technique known as cluster sampling, you split a population into groups, such as districts or schools, and then randomly choose a sample from among these groups. Ideally, each cluster should be a small representation of the population as a whole.

When studying large, dispersed populations, cluster sampling is most effective since interviewing every individual would be expensive, time-consuming, and sometimes impossible.

By using cluster sampling, it is possible to create smaller, more comparable clusters that represent the population being studied.

Thus, the researchers choose three freshmen seminar classes at random and polled every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.

The cost of each friendship bracelet in dollars and cents was J $7.75

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Abigail paid $62.00 for 8 friendship bracelets. Each bracelet cost an equal amount.

Cost of 8 friendship bracelets =  $62.00

Therefore,

Cost of 1 friendship bracelets =  $62.00/ 8

Cost of 1 friendship bracelets =  7.75

The cost of 1 friendship bracelets is $7.75

Answer:

D is the answer

Step-by-step explanation:

Answer:

6. 75 Students in Mrs.Reynolds class.

7. 60 Birthdays in February

8. February and May are a combined 20% of birthdays

9. March has 24% of the students birthdays

Step-by-step explanation:

6.   Adding all the numbers will give us 75 total students.

7.   450 divided by 7 will get us 6. And there are 10 birthdays in February, so we do 10 times 6 and get 60.

8.   On a calculator if you input 20% of 75 you will get 15. February and May are the only 2 birthday months that if you add them up you get 15.

9.   If you put 24% of 75 on a calculator you will get 18. March is the only month with 18 birthdays.

There is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Mrs. Reynolds creates a graph of the number of students who have birthdays in the first half of the year.

The graph has been given in the question.

Here y-axis represents Months and the x-axis represents the Number of students

As per the given graph, the required solution would be as:

Adding all of the numbers together generates a total of 75 students.

450 divided by 7 equals 6. And there are ten birthdays in February, so multiply 10 by 6 to get 60.

If you enter 20% of 75 into a calculator, you will obtain 15. February and May are the only two birthday months that total up to 15.

If you multiply 24% of 75 by 18, you get 18. March is the only month in which there are 18 birthdays.

Thus, there is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.

Answer:

Approximately 460 ft

Step-by-step explanation:

In any question where we have:

And we're asked to find:

We're gonna be using some trigonometry. The first question we've gotta ask is what we're looking for, and how the angles and sides relate to that. We're given:

And we're looking for:

How do our sides relate to the angle? Well, the 400 ft side is adjacent to 49°, and the side h is opposite. From SOH-CAH-TOA, we can see that the last trig function, tangent, is equal to opposite/adjacent. Let's turn this into an equation to bring it all together:

[tex]\tan{49^\circ}=h/400[/tex]

Solving for h, we find that

[tex]h=400\tan{49^\circ}\approx400(1.15)=460[/tex]

So the heigh of the hill is approximately 460 ft.

Answer:

z = -11

Step-by-step explanation:

-5Z = 55

to find z, divide each side by -5

[tex]\frac{-5Z}{-5} = \frac{55}{-5}[/tex]

z = -11

Answer:

Z = -11

Step-by-step explanation:

When dealing with variables, you want to get it alone so it instantly equals the number.

Since Z is being multiplied by -5, you're going to divide -5 because that's the opposite of multiplying--but you have to do it on both sides, not just the one.

Note that when you're dividing or multiplying a negative and positive number, the result with ALWAYS be negative!

                                                 -5Z = 55

                                                  /-5     /-5

                                                   Z =  -11

Just in case, we'll plug in -11 for Z and see if it works.

                                               -5(-11) = 55

Note again that when you're multiplying two negatives it cancels out the negative and makes the answer positive!
