Let the event ![A=\{ Sophomore \}, B=\{ Boy \}](https://tex.z-dn.net/?f=%20A%3D%5C%7B%20Sophomore%20%5C%7D%2C%20B%3D%5C%7B%20Boy%20%5C%7D%20)
The the probability of the events
![P(A \cap B)=\frac{5}{12+18} =\frac{1}{6}](https://tex.z-dn.net/?f=%20P%28A%20%5Ccap%20B%29%3D%5Cfrac%7B5%7D%7B12%2B18%7D%20%3D%5Cfrac%7B1%7D%7B6%7D%20%20)
![P( B)=\frac{12}{12+18} =\frac{2}{5}](https://tex.z-dn.net/?f=%20P%28%20B%29%3D%5Cfrac%7B12%7D%7B12%2B18%7D%20%3D%5Cfrac%7B2%7D%7B5%7D%20%20)
The conditional probability
![P(Sophomore|Boy)=P(A|B)=\frac{P(A \cap B)}{P(B)} =\frac{1/6}{2/5} =\frac{5}{12}](https://tex.z-dn.net/?f=%20P%28Sophomore%7CBoy%29%3DP%28A%7CB%29%3D%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28B%29%7D%20%3D%5Cfrac%7B1%2F6%7D%7B2%2F5%7D%20%3C%2Fp%3E%3Cp%3E%3D%5Cfrac%7B5%7D%7B12%7D%20%20)
28, 14, 7, 0 is a sequence for this
Answer:
1.01010 x 10³. Might vary if it asks for specific significant figures.
Answer:
Step-by-step explanation:
Work = (12 - 2) x 180 = 10 x 180 = 1800 degrees
Answer = 1800 degrees
Hope that helps!
