Answer:
25% or 1/4
Step-by-step explanation:
There altogether 100 boys and girls together and the probability of one color would be 25. Therefore 25/100 would your fraction but it has to be simplified so then the answer would be 1/4
Answer:
17
Step-by-step explanation:
In this problem, you can use the Pythagorean Theorem to find the hypotenuse, which is x. The formula for the Pythagorean Theorem is: , where <em>a </em>and <em>b </em>are the two lengths of the triangle, and <em>c</em> is the hypotenuse (which is x).
<u>Steps:</u>
-We know the two sides already, which are 15 and 8, so we can substitute <em>a </em>and <em>b </em>into the equation: (the <em>c</em> is the same as x, just letting you know)
-Then, simplify the equation to get: (I replaced <em>c</em> with x just so you can understand better that we are trying to find x, the hypotenuse)
-Add the 225 and 64 to get:
-Find the square root of both sides to get x by itself:
-Evaluate the equation to get: which simplifies to

Answer: 7/12</h3>
=================================================
Explanation:
There are B = 3+5+4 = 12 marbles total, of which A = 12-5 = 7 are not black. Or you could note that we have A = 3 red + 4 white = 7 marbles that are not black.
The probability of selecting a non-black marble is A/B = 7/12
7/12 = 0.5833 = 58.33% approximately
