The graph shows the function f(x) = |x – h| + k. What is the value of k? k = –2.5 k = –A. k = –2.5
1 answer:
<h3>The value of k is -2.5</h3>
<em><u>Solution:</u></em>
The graph of this question is attached below
Given is a graph V shaped two straight lines in graph
The function is given by:
To find: value of k
k is the y-coordinate of the vertex of the function
From graph, vertex is located at (1, -2.5)
Thus,
(h , k) = (1, -2.5)
Therefore,
k = -2.5
Thus value of k is -2.5

Step-by-step explanation:
Given that the midterm exam in Econ 2201 consisting of 50 students was worth 100 points. The top 5 scores were 75, 81, 88, 92, and 94.
We have to find the 95th percentile of the score distribution.
For this purpose let us arrange in ascending order
75, 81, 88, 92, 94
We must have 95% below the value we find out so that it would be the 95th percentile
i.e. here 95% means =
4.75 entries should be below that entry
We see that 80% entries are below 92 and 100% below 95
To find 95%
For 20 % difference differnce in score = 94-92 =2
Hence for 15% difference difference in score =
95th percentile= 92+1.5 = 93.5
