The answer to this will be a positive multiply 3 and 11 you'll get 33 and multiply 4 and 5 and you'll get 20
33/20
The answer is Standard Score (Or Z-Score)
Answer:
This is the graph of the question
Step-by-step explanation:
To find the average rate of change, its a secant line.
(a) someone over 55
mean, mu = 22
standard deviation, sigma = 2
X=19
Z(X)=(X-mu)/sigma=(19-22)/2=-1.5
P(x>X)=1-P(x<X)=1-0.0668072=0.9331928
Therefore probability for a 55-year old to find a job in over 19 weeks is 0.9332
