A scatter plot is made to model the number of calories in different portions of fish sticks. The data used for the scatter plot
are shown in the table: Number of portions 5 3 8 6 1 4
Number of calories 250 150 400 300 50 200
What does the slope of the model represent?
The number of calories in each portion of fish sticks
The number of fish sticks in each portion
The original number of portions of fish sticks
The price of each portion of fish sticks
Solution: A scatter plot is made to model the number of calories in different portions of fish sticks. The data used for the scatter plot are shown in the table below:
Number of portions
5 3 8 6 1 4
Number of calories
250 150 400 300 50 200
What does the slope of the model represent?
Answer: The number of calories in each portion of fish sticks
An arc of length 30 m : l = 30 m. r = 15 m, ∠ A = ? Formula for the length of an arc is: l = r π A / 180° ( where A is the central angle ) A = l · 180 / r π = ( 30 · 180 ) / ( 15 · 3.1415926 ) = 114.43 ° This is very close to your result.
