Answer:
3.24 minutes
Step-by-step explanation:
Use a calculator or chart to find the z-score.
P(Z > z) = 0.60
P(Z < z) = 0.40
z = -0.253
Find the time associated with the z-score.
z = (x − μ) / σ
-0.253 = (x − 4) / 3
x = 3.24
The slope of the graph is -1/2 using the rise over run method it rises up one and too the left twice so it would he -1/2
Answer:
No
Step-by-step explanation:
Definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output
Here we have more than one output for one input:
- x=-1 => y= -1, 0, 1
- x= 1 => y= 1, 2, 3
So this is not a function
