Having trouble with this one can somebody help?
Varvara68 [4.7K]
Form equation
y = mx + c
y = (rise/run).x + c
y = (11-1 / 3--2)x + c
y = 2x + c
11 = 2(3) + c
Find c (y-intercept)
11 - 6 = c
c = 5
Final equation of line
y = 2x + 5
Substitute given possible x-values in to find y-values
y = 2(1) + 5 = 7 (1,7)
y = 2(2) + 5 = 9 (2,9)
Therefore d is correct

Find the mean and the median of this data set: 9, 6, 5, 3, 28, 6, 4, 7
Ugo [173]

Answer:

The means is 8.5 The Median is 6

Step-by-step explanation:

1) to find the mean just Simply add all the numbers together and divided by how many numbers that is giving. (Because you are simply finding the average)

9+6+5+3+28+6+4+7=68

68 divided by 8 = 8.5

2) to find the median simply organize the numbers from least to greatest Like this: (3,4,5,6,6,7,9,28) Then keep crossing out from both sides teal you find the middle Number.

If there a odd amount of number the median will be one Number, if even 2 numbers ( if 2 numbers just add them both and divide by 2)

In This Case the Median is 6,6 but Its actually 6 Why (6+6=12) and (12/2=6) so your median is 6.
