The rules are player a wins every time the signs are all the same, b wins every time two players have the same signs, and player c wins every time all the signs are different. My prediction is that player B will win. The results of my game were good and we were right that b would win 18/27 times. The outcome that occured the most was b which is 18/27. The outcome occurted the least was a with 1/27.The experimental probability matches the theoretical probability because b won. This game is not a fair game. You could make it fair by having four people play.

The outcome that occured the most was B which is 18/27.The outcome that occured the least was A with 1/27 all of the same like all rocks. The experimental probabilitie matched my theoretical probabilities because B won. The game is not fair, You could change this game to make it more fair by letting four people play.

In the game stick or switch you must choose between three doors. The point of the game is to pick the door with the prize. The graph shows the wins and loses. We found that when you switch you win 61% of the time and when you stick you only win 38% of the time. Also, when you switch you lose less, only 36% of the time and when you stick you lose more, which is 63% of the time. Inconclusion, your best stragety is to switch because you will win more of the time.

doubling surface area

If the surface area was 15 cm squared and was doubled the new surface area would be 60 cm squared.

Derived Measurements

I know there are 60 seconds in one minute. First, I found the product of 15x4, which is 60 I did that because you have to find how many beats in one minute. Then, I found the sum of 16+16+16+16 which is 64. The solution is 64 beats/one minute.

Composite Shapes Extened Response

I think Chelsey will need the smaller bag to cover the area of her yard. First, I divided the shape into smaller shapes, I did this because this shape is a composite shape. Second, I muliplyed 50x30 to find the area of the parallelogram which is 1,500ft sq. Then, I found the area of the square, which is 50x50=2,500ft sq. Next, I found the area of the triangle, I did this by mulipying 50x30 which is 1,500, then I divided 1,500 by 2 and got 750ft sq, I divided by two because the formula to find the area of a triangle is base times hieght divided by 2. Last, I added 1,500, 2,500 and 750 all togetherand got 4,750. Inconclusion, that is why I think she will need the smaller bag.

Similar Triangles Extened Response

To get the length of the shadow I did many different things. First, I drew a picture of similar triangles. Second, I converted 60 inches into feet and I fot 5 feet, so Katie is 5 feet tall. Next, I made a proportion to get the length of the post's shadow, what I did was made a ratio with corresponding sides which would be 5 feet and 25 feet, and 14 and x. Then, I muliplyed 25 and 14 and got 350, then I divided 350 by 5 and got 70. So the length of the shadow would be about 70 feet.

Sfficient Properties ext. resp

A square is also a parallelogram by having congruent sides. A rectangle is also a square because it has right angles and congruent sides. A square is also a rhombus because they both have all sides congruent and they are all parallel, also thier angles are all congruent which makes them both regular quadrilaterals.

Percent Extended response

I did problem 19 and the question was to put 3/5, 66%, 35%, 2/3 in order from greastest to least. I did this by making the fractions have a demominator of 100. The two fractions were 3/5, which is now 60/100 and 2/3, which is now 66/100. So those fractions would be equivalent to the fraction I started with. After I did that I changed the percents into fractions. By doing that I got 66/100 and 35/100. The new list is 66/100, 66/100, 60/100, 35/100. That is how I got my answer 2/3, 66%, 3/5, 35%.
