Answer:

x=-1 y =-1

Step-by-step explanation:

multiply equation 1 with (-2)

+6x-2y=-14

5x+2y=3

now add equation 1 to equation 2

11x=-11

x=-1

now substitute x=1 in 1 or 2

5(1)+2y=3 5+2y=3 2y=3-5 2y= -2 y= -1

In the data set below, which of these points is most likely and outlier?
shusha [124]
<h2>Answer:</h2>

Option: D is the correct answer.

                 D.  (2,54)

<h2>Step-by-step explanation:</h2>

We know that an outlier of a data set is the value that stands out of the rest of the data point i.e. either it is a too high value or a too low value as compared to other data points.

Here  we are given a set of data points as:

         (2,54)

          (4,7)

         (6, 9)

         (8,12)

         (10,15)

Hence, we see that the output values i.e. 7 in (4,7) ; 9 in (6,9) ; 12 in (8,12) and 15 in (10,15) are closely related.

Hence, the data point that is an outlier is:

                  (2,54)

(As 54 is a much high value as compared to other)
