Rin incorrectly calculated the mean absolute deviation for in which step did Rin make an error?
the data set 25,25,31,36,38. Her work is shown here.
1. Find the mean
Mean = 25 * 25 * 31 * 36 * 38 155 = 31
2. Find each absolute deviation,
Absolute deviations:6,6,0,5,7
3. Find the mean absolute deviation.
MAD : 6 *0* 5+7 - 18 - 4.5
which step did rin make an error?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

b if for most of the graph

d if y intercept
