2 times a number, x, is equal to 6 less than 3 times the number, x.
2x = 3x - 6
-1x = -6
x = 6
The number is 6.
100*2.2=220
80*2=176
220+176=396
So the two trains will take 2.2 hours so that they are 396 miles apart.
Answer: Our required probability is 0.515.
Step-by-step explanation:
Since we have given that
Probability that the respondents voted in favor of Scot Walker P(F) = 56%
Probability that the respondent voted in not favor of Scot Walker = 100-56 = P(F')=44%
Probability of those who did vote in favor had a college degree = 36% = P(C|F)
Probability of those who did vote against had a college degree = 44% = P(C|F')
So, we will use "Conditional Probability":
probability that he voted in favor of Scott Walker given that they had a college degree is given by
![P(F|C)=\dfrac{0.56\times 0.36}{0.56\times 0.36+0.44\times 0.43}\\\\P(F|C)=0.515](https://tex.z-dn.net/?f=P%28F%7CC%29%3D%5Cdfrac%7B0.56%5Ctimes%200.36%7D%7B0.56%5Ctimes%200.36%2B0.44%5Ctimes%200.43%7D%5C%5C%5C%5CP%28F%7CC%29%3D0.515)
Hence, our required probability is 0.515.
