The mean of a set of data is 3.77 and its standard deviation is 3.39. Find the z score for a value of 6.19

1 answer:

6 0

Z = (x - mu)/sigma
z = (6.19 - 3.77)/3.39
z = 0.71386430678467
z = 0.71

The approximate z score, rounded to two decimal places, is 0.71

Answer:

(2, - 9 )

Step-by-step explanation:

Since 2 is the output when - 9 is input to f(x)

Then reversing the procedure, that is the inverse gives an output of - 9 for an input of 2.

(- 9, 2) is a point on the graph of f(x), then

(2, - 9) is a point on the graph o the inverse function $f^{-1}$ (x)
