Answer:
The answer is C, 0.25.
Step-by-step explanation:
In order to find the probability of (B | A), you need to use this formula:
Conditional Probability (A has already occured)
P(B | A) = P(A and B)
-------
P(A)
If you subsitute in the values you get this:
P(B | A) = 0.10
------
0.40
0.1 divided by 0.4 is equal to 0.25.
Alright, so the equation we have here is 22.75x+32=128.69
Now we just solve
-32 on both sides, we get
22.75x=96.69
divide by 22.75 on both sides we get
x=4.2501989
So 4 hours
You add the 4.25 hours
10, 11, 12, 1 is the hour
And .25 is a fourth, and a fourth of 60 minutes is 15 minutes
So he left at 1:15 pm
139/8 = 17.375 (this is rounded)
135/7 = 19.286 (this is rounded)
so he rode farther on Sunday
135/7 - 139/8 = 107/56 or 1 51/56 miles farther
