Amelia’s teacher provides her with this spinner, which has four equal sections. Amelia has never seen this particular spinner before, and she is asked to create a theoretical probability model of one spin. In case it is a trick spinner, Amelia decides to complete 300 spins, and the results are shown in the table.

Outcome 1 2 3 4
Frequency 68 81 77 74
a. If the spinner was fair and spun 300 times, each outcome would be expected to be observed
times.
Question 2
b. Based on the data from the 300 spins, does it seem like the spinner is a fair spinner?

Yes
Yes

No
No
Question 3
c. Why or why not?

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
