Answer: The correct option is C.
Explanation:
A function is called an odd function if,
It means if the points are in the form of (x,y) then (-x,-y) is also in the graph.
Reason for correct option:
In option C, a point (1,2),
It means,
And we have another point (-1,-2).
The other points are (2,3),(-2,-3),(3,-1),(-3,1),(4,0),(-4,0). Therefore the function is an odd function.
Reason for incorrect option:
In option A, a point is (1,3), therefore the value of function at x = -1 should be -3.
But the value of function is 1 at x=-1, therefore it is not an odd function.
In option B, a point is (1,0), therefore the value of function at x = -1 should be 0.
But the value of function is -3 at x=-1, therefore it is not an odd function.
In option D, a point is (1,-1), therefore the value of function at x = -1 should be 1.
But the value of function is -1 at x=-1, therefore it is not an odd function.
Answer:
(a) 83% of the scores were at or below her score.
(b) 17% was above her score.
Step-by-step explanation:
Given that:
Percentile score of Angela in the general aptitude test = 83rd percentile
To find:
a) Percentage of scores which were at or below her score?
b) Percentage of score which were above her score?
Solution:
First of all, let us learn about the term "<em>Percentile</em>"
Percentile is the value below which the certain percent of people/marks fall.
Therefore, when we say percentile of someone's score is , then there are
of scores are at the same level or below.
And of the scores are above this level.
Therefore, we can say that:
83% of the scores were at the same level or below the score of Angela.
And of the scores were above the score of Angela.
