In a group of 36 students, 6 study both Art and Biology.
vichka [17]
<h2>Greetings!</h2>

Answer:

\frac{1}{6}

Step-by-step explanation:

If the total data set is 36 students, and you need to find out the probability that the randomly selected student studies both art and biology, you need to find the ratio:

Every 36 students there is 6

36 : 6

Divide both sides by 6:

6 : 1

So that means the probability is:

\frac{1}{6} or 1.16 recurring

Please help me with this math problem! I'm really confused.
MissTica

Answer:

48

Step-by-step explanation:

You will be using the  Pythagorean theorem for this problem. assuming the bigger triangle is double the size of the smaller triangle on the right, we would first plug in the numbers for the smaller triangle: 16^{2}  + B = 27^{2} which would come out to  21.7. then we could say that since like i said before the bigger triangle is double the other one, the bottom side of the triangle would be 32 (16 + 16) and would use the pythagorean theorem again, giving us our answer.
