Median is the middle data in the list of the given numbers. In the given data set the median gets decreased by the presence of the outlier. Thus, option C is correct.

<h3>What is an outlier?</h3>

An outlier is a data that varies significantly from the other data set, due to some error or measuring variability.

The median of the data without outlier is calculated as:

First, data is arranged in the ascending order: 105, 108, 109, 113, 118, 121, 124

Median = \rm \dfrac{7 + 1 ^{th}}{2} term

= 4th term

= 113

The median of the data with outlier is calculated as:

First, data is arranged in the ascending order: 61, 105, 108, 109, 113, 118, 121, 124

Median = \rm \dfrac{(\dfrac{8}{2})^{th}  + (\dfrac{8}{2} + 1)^{th}} {2}

= (109 + 113) ÷ 2

= 111

Therefore, the outlier decreased the median.

Which are steps that could be used to solve 0 = 9(x2 6x) – 18 by completing the square? Check all that apply. 18 81 = 9(x2 6x 9)
Marina CMI [18]

Answer:

18 + 81 = 9(x² + 6x + 9) 11 = (x + 3)²

Explanation:

because  This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:

18 + 9 (9) = 9 (x² + 6x + 9)

18 + 81 = 9 (x² + 6x + 9)

99 = 9 (x² + 6x + 9)

Dividing both sides by 9, we have:

11 = x² + 6x + 9

11 = (x + 3) ²

Artyom0805 [142]

There are different kinds of vendors. The best that I can identify and recommend is Vendor V in the diagram attached.

The seasonal product team should consider taking or using Vendor V. This is because of their performance. When you look at the diagram, you will see that their performance is better in all parameter given in the table (Diagram attached).

Vendor V is in all parameters improving the performance of all the  four elements and it can easily adjust to any seasonal changes.
