Mean: The sum of all the numbers, divided by the amount of numbers in the set.

56 / 9 = 6.2

Median: The middle value of a set.

7

Mode: The value that occurs most frequently.

9

Range: The highest number of the set subtracted by the lowest number.

10 - 1 = 9

Hope this helps you!

Median: 7 because it is in the very middle of the numbers

Mean: add up all the numbers and divide by how many numbers there are. So the mean should be 56÷9=6.2. 6.2(2 is repeating) is the mean

Range: the range is the difference between the highest and lowest numbers. so that means the range is 10-1=9. the range is 9

Find the slope of the line that passes through (8, 3) and (1, 9).
leonid [27]

Answer:

-\frac{6}{7}

⇒ m = \frac{9 - 3}{1 - 8}

⇒ m = \frac{6}{-7}

Correct                                 Incorrect  

B)

3(6) + 4(-5) = -2                    2(6) - 4(-5) = -8  

18 - 20 = -2                            12 + 20 = -8

Correct                                 incorrect

C)

3(4) + 4(4) = -2

12 + 8 = -2

D)

3(-2) + 4(1) =-2                        2(-2) - 4(1) = -8

-6 + 4 = -2                                 -4 - 4 = -8

Correct                                      Correct

What is 16 out of 24 as a grade
Dominik [7]
16 out of 24 would equal around 67%, and that as a grade would be a D.
However, grades MAY vary from school to school.
But on average:
A= 100 through 90, B= 89 through 80, C= 79 through 70, D= 69 through 60, and an F= 59 and below that.
Keep in my mind that if your grade has digits after the decimal, it will be rounded (in your case) and that may also change your grade, for example if your grade is 79.7%, then it will be rounded to 80%, and your grade will be a B.
