1.rearrange your data from least to greatest:
0,0,1,1,2,2,2,14 

middle is 1 and 2 ... so median is 1+2/2= 1.5 and it is the median not the mean
2.I believe the only outlier is 50. Finding the mean would be 80.11.
The answer would be D
3.D. Mean always goes toward the skewness due to outliers.
Median is minimally affected by outliers.
4.We remove an outlier because we can simply assume that there was some type of extreme experimental error, or something went wrong. The mean shouldn't be effected that much, but the median will be greatly effected.

Which of the following is the solution to the inequality below? 9-3x>2(x-3)

Inessa [10]

9 - 3x > 2(x - 3)
9 - 3x > 2x - 6
Subtract 2x from both sides.
9 -5x > -6
Subtract 9 from both sides.
-5x > -15
Divide both sides by-5.
x < 3

More help pls! 3 and 4

Leya [2.2K]

Answer:

3. One Solution. (0,4). (they have different slopes and y-intercepts)

The solution can be found using elimination method:

Add the equations together

y = -x + 4

y = x - 4

2y = 0

y = 0

Solve for x

0 = x - 4

x = 4

(4, 0)

4. No solution

x + y = -2 and 3 which is not possible

The two lines would be parallel

How do we find the quadratic equation in standard form with the given roots of -1/3, 5?

Olin [163]

I think this is the answer. Because it doesn’t mention a leading coefficient but it’s a quadratic function so it would be
1(x-1/3)(x-5) and that should be your answer. The simplified version is down below
