Anthony is making a collage for his art class by picking shapes randomly. He has five squares, two triangles, two ovals, and fou
r circles. Find P(a triangle or a square is chosen first).
2 answers:
We have 13 total shapes and 7 of them meet the criteria, so the probability is:
<span>
</span>P(<span>Square or Triange) = </span>
<span>or about
0.3888.....
or
38.88%</span>
Total shapes:
5 + 2 + 2 + 4 = 13
Probability of triangle: 2/13
Probability of square: 5/13
Probability of triangle or square: 2/ 13 + 5/13
= 7/13

(D.) It should be a bit less than 6 quarts (5.75 / 5 & 3/4 to be exact)
Simplify each side in order to determine if true.
the answer is: False
A,b are 8,2. its an easy guess.
now that makes it easy
Y = 4/5x - 1 rise over run and when x = 0 y = -1
