Answers

Answer 1

Answer: Set A Range= 9  MAD: 2.88

Step-by-step explanation:

Range is the difference of the largest number and smallest number in a set

MAD: 1) find the mean of the set of numbers (add them, then divide by how many numbers you added together.

2) find the absolute value of each number - the mean you found.  

3) find the mean of all the absolute values you found in step 2

*1) 21+26+27+28+21+20+25+27+29+22=246/10=24.6

*2) Absolute value of:

21-24.6= 3.626-24.6= 1.427-24.6= 2.428-24.6= 3.421-24.6= 3.620-24.6= 4.625-24.6= 0.427-24.6= 2.429-24.6= 4.422-24.6= 2.6

*3) mean of values from step 2

(3.6+1.4+2.4+3.4+3.6+4.6+0.4+2.4+4.4+2.6)/10= 2.88

MAD=2.88

Follow the same steps for the second set of numbers

Answers

Answer:

1. a

2. Circle

3. B

4. Degrees

Step-by-step explanation:

The variable (a) represents the number of equal parts into which the (Circle) is divided. The variable (b) represents the number of (Degrees).

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

The equation 360°÷a=b can be used to find an angle measure in a circle.

360° = ab.

Here, a and b are the variables of the equation. and 360 degrees is the complete angle of the arc of a circle.

The variable (a) represents the number of equal parts into which the (Circle) is divided. The variable (b) represents the number of (Degrees) in each part.

The dot plot shows a random selection of commute times in two cities.

Answers

Answer:

The commute times are shorter and more predictable for City B.

Step-by-step explanation:

First, let's find the center of each set of data. We don't have to actually measure it, we can just approximate. For City A the center is around 30 minutes. For City B the center is around 15 or 20 minutes. We can clearly see that City B commute times are generally shorter than City A.

Next, let's find which city is more predictable. We can figure this out by looking at each city's range. City A has a range of 55. City B has a range of 35. Because City B has a smaller range, we can say that City B's commute times are more predictable.

Noooo Linnkkkkkk Rodney ordered a large sub sandwich. He ate 1/4 of the sandwich on monday and 1/3 of it on tuesday. Which equation shows how to find how much of the sandwich Rodney ate ate in all?
A. 1/4 + _ = 1/3
B. 4/7 + 5/7 = _
C. 4/12 + 5/12 = _
D. 3/12 + 4/12 = _

Answers

Answer:

d.

Step-by-step explanation:

3/12 simplified is 1/4, 4/12 simplified is 1/3. they want to know how much rodney ate total, so simply it's the same as 1/4 + 1/3 ;; just with common denominators so it is easier to solve.

edit: the __ represents the total on how much they ate.

The equation used to describe total amount of sandwich he ate will be

3 / 12  +  4 / 12  = 7  /  12.

What is an equation?

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

It is given that:-

He ate 1/4 of the sandwich on Monday and 1/3 of it on Tuesday

So the equation to calculate the total amount of sandwiches he ate will be:-

=  1  /  4  +  1  /  3  

We can also write the above equation as:-

=  3  /  12  +  4  /  12

= 7  /  12

Therefore the equation used to describe the total amount of sandwich he ate will be  3 / 12  +  4 / 12  = 7  /  12.

Step-by-step explanation:

If you add up the numbers on top for the first, secnd, and fourth ones and divide that by the number ont he bottom, you will constantly get 6. However, for the third one, you'll get seven since 9+9 is 18 and 5+5 is 10. Add that up and you get 28, and divide that by 4 and you get 7, not 6. hope this helps!

Answer: (9+9+5+5)/4

Answer:  C) Three-fourths

======================================================

Explanation:

Let's pick on the horizontal sides. Divide the image length Y'Z' = 9 over the corresponding preimage length YZ = 12 to get

(Y'Z')/(YZ) = 9/12 = 3/4 which is the scale factor

The scale factor is less than 1, meaning the image's lengths are shorter compared to the preimage's corresponding lengths.

-----------------

Alternative Paths:

You can pick any other pair of corresponding sides to get the same result:

(X'Y')/(XY) = (7.5)/(10) = 75/100 = 3/4(Z'X')/(ZX) = 6/8 = 3/4

Answer:

[tex]scale ~factor= Z'Y'/ZY[/tex]
