yawa3891 [41]

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.

How should I write this as an equation and how is the answer 1:15 am?
SVETLANKA909090 [29]

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

Carlos biked 139/8 miles on Saturday and 135/7 miles on Sunday. On which day did he ride further and by how much?
SCORPION-xisa [38]
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
