Use the data to answer the following questions: 68, 63, 67, 66, 65, 87, 69, 61, 86, 82, 28
1 answer:
Rewrite given data in increasing order:
28, 61, 63, 65, 66, 67, 68, 69, 82, 86, 87
An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. As you can see that number 28 lies an abnormal distance from other values.
Answer A: 28

Answer:
(a) (-2, 4)
Step-by-step explanation:
The orthocenter is the point of concurrence of the altitudes of the triangle.
A plot of the triangle vertices shows the triangle to be acute. That means the orthocenter is inside. This eliminates choices B, C, D, which are all points outside the triangle.
__
Conveniently, side LM is horizontal. This means the orthocenter will have the x-coordinate of the vertical line through N, which is -2. Only one answer choice has an x-coordinate of -2:
a (-2, 4)
