Cassidy’s family is driving home from vacation at an average speed of 55 mph.
Initially, at x = 0 hours, the family is y = 0 miles away form home. We get the first point (0,0).
After x = 2 hours, the family is y = 110 miles from home. We get the second point (2,110).
The equation in point-slope form that represents their distance y from home, after x hours is

Answer:
z-score = 3.5, Yes, z-score is unusual.
Step-by-step explanation:
Given information:
Population mean ; μ = 6 feet
Standard deviation ; σ = 0.2 feet
Sample mean = 6.7 feet
The formula for z-score is
where, is sample mean, μ is population mean and σ is standard deviation.
Substitute the given values in the above formula.
The z-score is 3.5.
If a z-score is less than -2 or greater than 2, then it is known as unusual score.
3.5 > 2
It means z-score is unusual.
