Suppose that Frida selects a ball by first picking one of two boxes at random and then selecting a ball from this box at random. The first box contains four white balls and one blue ball, and the second box contains four white balls and one blue ball. What is the probability that Frida picked a ball from the first box if she has selected a blue ball? (Enter the value of the probability in decimal format and round the final answer to one decimal place.)

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.

did u ever get the answers? i need
