Set up the equation ... 60 + 40X = total charges... where X is the number of hours (8.5)
60 + 40(8.5) = ?
60 + 340 = ?
400 = total charges
Slope = (y2 - y1) / (x2 - x1)
(0,4)...x1 = 0 and y1 = 4
(-8,-1)...x2 = -8 and y2 = -1
now we sub and solve
slope = (-1 - 4) / (-8 - 0) = -5/-8 = 5/8 <=
Answer:
The z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 161 pounds
Standard Deviation, σ = 23.5 pounds
x = 220 pounds
Formula:
Putting values, we get,
![z_{score}=\dfrac{220-161}{23.5}=2.5106](https://tex.z-dn.net/?f=z_%7Bscore%7D%3D%5Cdfrac%7B220-161%7D%7B23.5%7D%3D2.5106)
Thus, the z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00
