The first quartile of a data set is 18, the median is 25, the third quartile is 28,

1 answer:

7 0

The outlier would be shown as a dot so the answer is B. 45
The interquartile range is 28 - 18 = 10
A simple rule is that points more than 1.5xIRQ above or below the medians is an outlier and is shown as a point.
28 + 1.5x10 = 43. 45 is above this value.

Answer:

7 -1 6 | -8

7 -5 7 | 1

0 1 -4 | -5

Step-by-step explanation:

Note that there are four columns in this system, representing the variables x, y and z and constants. So the given matrix pattern is appropriate: It has three columns for the coefficients of x, y and z and one column for the constants.

We need only identify the coefficients and transfer them into the appropriate boxes of the matrix pattern.

We get:

7 -1 6 -8

7 -5 7 1

0 1 -4 -5

7 0
