Answer:
abc = def
Step-by-step explanation:
abc = tuv
tuv = def
abc = def
Answer:
The second option
Step-by-step explanation:
To solve this, you should convert both rates to equations, with y being the total fare, and x being the number of miles. The rates of both use the format y=mx+b (where m is the amount per mile and b is the flat rate, or original rate).
By subbing in the values for m and b, you get y=2x+4 for A and y=3x+5 for B. This is the second option.
**This question involves writing linear equations, which you may wish to revise. I'm always happy to help!
Answer:
The probability that the new baby just born is a boy is 0.6
Step-by-step explanation:
- B=Event where the nurse picked up a boy
- G=Event where the nurse picked up a girl
Applying Bayes's Theorem:
P(A|B)=P(A) P(B|A) / [ P(A) P(B|A)+ P(C) P(B|C) ]
Where:
- P(A|B)=probability that the new baby just born is a boy given that the nurse picked up a boy.
- P(A)=Probability that the woman had a boy= 1/2
- P(C)=Probability that the woman had a girl=1/2
The probability for P(A) and P(C) is 1/2 becuase there are only two options. Girl or Boy
n= number of girls born
3+n= Total number of children in the nursery
Then,
P(A|B)=![\frac{\frac{1}{2} \frac{3}{3+n} }{\frac{1}{2} \frac{3}{3+n} + \frac{1}{2} \frac{2}{3+n}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7D%20%20%5Cfrac%7B3%7D%7B3%2Bn%7D%20%7D%7B%5Cfrac%7B1%7D%7B2%7D%20%20%5Cfrac%7B3%7D%7B3%2Bn%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Cfrac%7B2%7D%7B3%2Bn%7D%7D)
P(A|B)=3/5
P(A|B)=0.6
