Easy Problem: This problem uses some experimental probability. All you do is put the number of what you want over the total amount of objects. For instance, if there was a bag with 1 red jolly rancher and 2 blue jolly ranchers and you wanted to pull out the red one, put 1 red jolly rancher over 3 total jolly ranchers to get 1/3 = 33.3%.
I have a bag with c green marbles and n/z red ones. If I pull out y marble(s), what are the odds that the marble will be green? Express your answer in a percentage.
Hard Problem: To determine the area of a trapezoid, take the two bases and add them together. Then, multiply that sum by the height, and divide that answer by two. This will give you the trapezoid's area.
Hint: To convert inches to centimeters, divide the measurement by 2.54.
1) Convert measurements a and b from Monday to centimeters. On Monday, there were in inches, but we are measuring in centimeters!
Our centimeter conversion for a will be equal to z.
Our centimeter conversion for b will be equal to p.
2) Calculate the height of this trapezoid using sines and trigonometry.
|This is the trapezoid you will use to solve the problem.|
h = ____
3) Determine the area of this trapezoid. Your answer should be expressed in square centimeters.
If you completed one or both equations, send me your answer. I will tell you if you are correct and list you as one of the people who completed it.
