Answer:
81.2 is the 62th percentile
Step-by-step explanation:
What is the interpretation for a percentile?
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
300 observations, there are 186 points less than 81.2. Find the percentile for 81.2.
So
slope = 0
point1 = (0,7)
point 2 =(7,7)
slope = (y2-y1)/(x2-x1) => (7-7)/(7-0)
The answer should be A. Y= -4x -9
(f + g)(x) = f(x) + g(x) therefore (f + g)(4) = f(4) + g(4)
x>-4 x≤-8
