Do you think the three groups are very different or not?

Answer:

B. and D.

Step-by-step explanation:

I believe it's right because it is uniform and im pretty sure they are not the same though

The probability model for this situation is

The probabilities of the individual outcomes are the same.

and, The probability model for this situation is uniform.

The correct option is (C) and (D).

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

Given:

A spinner has 5 equally sized sections labeled A, B, C, D, and E.

As,

P(A)= P(B)= P(C)= P(D)= P(E)= 1/5, which is same.

The probability model for this situation is uniform.

Hence, The probabilities of the individual outcomes are the same.

and, The probability model for this situation is uniform.

Step-by-step explanation:

Answer:

7.2 | 6.2 | 2.2 | -2.8 | -3.8 | -8.8

0.2

Step-by-step explanation:

Step 1) Find the mean

How to find it?

Add all the numbers listed above and divide by the number of numbers in the set (6)

This mean you should get 67/6=11.2

Step 2) Find the distance from the mean.

How do I do this?

Since you are trying to find the difference you will use the equation 11.2-(number)

Example) 11.2-4=7.2

This will give you the answers for the second half of the table.

Step 3) Find the mean of those distances to find the mean absolute deviation

How do I do this?

Add all the numbers on the second half of the table and then divide by 6. This will give you your mean absolute deviation.

I hope this helps! :D

Answer:

Total amount = 7x + 25

Step-by-step explanation:

Assuming that week can be denoted by a variable, in this case, x. Also assume that the total amount owned is denoted by the variable, y.

Note that $25 is the constant, meaning that that amount will not change. Norm would technically have at least $25 regardless of how much week passes.

The amount that changes per week is the addition of $7.

Set the equation:

Total amount = ($7 per week x  amount of week(s)) + starting amount (constant).

Total amount = 7x + 25

Answer:

the ansere is -20

Step-by-step explana

The speed is given by the arithmetic mean. Then the jet Alyssa's average speed on the round trip is 540.

The total distance covered by the particle or the body in a total time is called average speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the average speed formula

[tex]\rm v_{a} = \dfrac{v_1+ v_2}{2}[/tex]

The speed of the jet Alyssa flew on from Boston to London was 480 mph.

On her return flight, the speed of the jet was 600 mph with a tailwind.

Then the average speed of the jet will be

[tex]\rm v_{a} = \dfrac{v_1+ v_2}{2}\\\\v_{a} = \dfrac{480 + 600}{2}\\\\v_{a} = 540\ mph[/tex]

Answer: C) He should also take a sample from each of the other history classes in all of the other grades in the middle school.

Step-by-step explanation:

In order for his sample to be representative of all middle school students Leo: C) Should also take a sample from each of the other history classes in all of the other grades in the middle school.

Sample can be defined as the data that is randomly collected by a researcher so as to reach or draw a conclusion.

Since only one grade is being surveyed which is Mr. Barnes’s eighth-grade history classes, he should as well carryout the survey on Ms. Lopez and Mrs. Frank history class.

Inconclusion he should also take a sample from each of the other history classes in all of the other grades in the middle school.

Not only students in the 8th grade are in the middle school, there are other students in other grades who are in the middle school and are enrolled in history classes. Leo's sample is only from one grade of the middle school. In fact, including Ms. Lopez's and Mrs. Frank's classes in the selection of sample is not sufficient. Leo has to take a sample from the remaining grades to avoid making a wrong conclusion as a result of bias in the choice of data.

Answer:

step one!

Step-by-step explanation:

I could be wrong, let me know!

To solve for the Principal amount, we will use the formula:

                            P = I / rt

P = principal amount; which is the amount that we will be solving for.

I = the interest accrued within the allotted time frame. ($160)

r = the interest rate percentage. (1.6%)

t = the time frame that the money will accrue interest. (2 years)

Before we can plug in the numbers into our formula, we need to convert our percent into a decimal. To do this, move the decimal two places to the left. This will leave us with 0.016. We'll use that for "r".

Let's plug in the numbers:

P = 160 / (0.016) (2)

Multiply your bottom numbers together for 0.016 x 2 =0.032

P = 160 / 0.032

Divide now.

160 ÷ 0.032 = 5,000.

This tells us that, Bert will need to deposit $5,000 into the savings account to earn $160 within 2 years with a 1.6% interest rate.

Answer:

Option C, 488 square centimeters

Step-by-step explanation:

Step 1:  Determine the area of the rectangle

[tex]A = l * w[/tex]

[tex]A = 22\ cm * 17\ cm[/tex]

[tex]A = 374\ cm^2[/tex]

Step 2:  Determine the area of the triangle

[tex]A=\frac{h*b}{2}[/tex]

[tex]A=\frac{19\ cm * (22\ cm-10\ cm)}{2}[/tex]

[tex]A=\frac{19\ cm * (12\ cm)}{2}[/tex]

[tex]A=\frac{228\ cm^2}{2}[/tex]

[tex]A=114\ cm^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 374\ cm^2 + 114\ cm^2[/tex]

[tex]A_{total} =488\ cm^2[/tex]

Answer:  Option C, 488 square centimeters
