Find the mean of this data set: {– 78, -12, 3, – 44} - 32.75
B
- 26.75
10.75
D
41.25
E
USTSP-5

Answer: A. -32.75

• f(n) are the values of the set

• n is the number of items

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
