Answer:
37th percentile.
Step-by-step explanation:
We have been given a data set that represents the ages of 36 executives. We are asked to find the percentile that corresponds to an age of 41 years.
28, 29, 29, 32, 32, 33, 34, 34, 34, 34, 37, 37, 38, 41, 41, 42, 45, 45, 47, 47, 47, 48, 50, 51, 53, 56, 56, 56, 61, 61, 62, 63, 64, 64, 65, 66.
Let us count the number of data points below and at 41.
We can see that the number of data points at and below 41 is 13.
We will use percentile formula to solve our given problem.
Therefore, the percentile rank that corresponds to age of 41 years old is 37th percentile.
Answer:
A circle can intersect a parabola in
1. One point [ when circle just touches the parabola]
2. Two points [ When circle cuts the parabola in two distinct points. ]
3. Three points [Circle just touches at one point and cuts the parabola in two distinct points]
4. Four points [ Either parabola or circle meeting each other or crossing at four distinct points]
