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]
To find the circumference multiply the diameter by PI.
Using 3.14 for PI, the circumference = 3.14 x 24 = 75.36 inches. Round the answer as needed.
A. this would be -1 because that is the y intercept as in where it meets the y axis.
b. the slope or rate of change would be 3 or 3 over 1. just follow the y=mx+b form. m=slope and b=yintercept or where the line meets the y axis. hope I helped
