On the histogram below, indicate the mean.
What is the standard Deviation?
The standard deviation is where the graph forms a hump. A large S.D makes the hump wider and shorter. A small S.D makes it tall and skinnier.
What is the difference between accuracy and precision? You may answer this with an example if you wish.
Accuracy= close to target
Precision= same spot every time (or in close range)
Colton drives his motorcycle on Friday to Tok 370 miles away. If he drives 74 mph, how long does it take him?
distance / rate = time
370miles / 74 mph = 5 hours
At the same speed, how far will he travel in four hours?
rate x time = distance
296 miles
On sunday, he drives from Tok to Fairbanks. It's 180 miles and it takes him 1.5 hours. What is the average speed for this trip?
How long is this cockroach?
How long is this stinkbug?
How are your answers for #7 and #8 different in terms of precision?
Figure 17 is a graph of the position of Billy the beetle as he attempt to steal Susan's bowl of oatmeal. During which time period is he traveling the fastest?
Explain your answer for the last question?
What is the average speed between 1 and 3?
When is he stopped?
Explain your answer for the last question.
When is his velocity "negative"?
Explain your answer for the last question?
What is the average velocity for whole trip?
Explain your answer for the last question.
