Answer:
Z-score = -1.285
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 17.6 seconds
Standard Deviation, σ = 2.1 seconds
Formula:
For x = 14.9, we have:
A z-score to be unusual if its z-score is less than -2.00 or greater than 2.00.
Thus, the z-score is not unusual as it lies in the range [-2.00, 2.00]
Answer:
a.
b.
c. x=26; y=24 or (24,26)
Step-by-step explanation:
Let x = number of teachers hired.
Let y = number of tutors hired.
Now solving for part a we get
a. Write an inequality that represents the statement that the number of teachers hired must exceed the number of tutors hired.
solving for part b we get;
b. Write an inequality that represents the statement that the maximum number of teachers and tutors is 50.
solving for part c we get;
c. Choose a point that satisfies the situation, and explain why you chose that number of tutors and teachers.
Now we know that also
x=26; y=24
(24,26)
Explanation: To make number of teacher more than number of tutors this is the maximum value we can achieve for the requirement.
