BRAINIEST TO WHOEVER RIGHT NOW PLZ. I NEED IT DONE NOW

21.

Step-by-step explanation:

An outlier is basically a data point that is just significantly different from other data values (way higher or way lower.)

However, you can see that most of the data points range in the 50-70 points, except the 21. Therefore, it is an outlier.

The outlier will be 21.

Step-by-step explanation:

As we can see, most of the points are in the 50, 60, 70 range.

There are none in 30 nor 40.

21 is far away from the 50, 60, 70 range (where most points are), so therefore, it is an outlier.

lol.

it's ok we all do this sometimes.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
