Imagine you have a motorboat with a maximum water speed (the speed relative to the water it's floating on) of 18 miles per hour(mi/h). We make the trip upstream from our cabin to our cousins cabin, a distance of 18 miles running the boat at top speed all the way. The trip takes 1 hour ad 12 minutes. We would expect it to take exactly an hour if there were no current in the river, but the current we were fighting slowed us down. how fast was the river flowing? assume the river flowed at the same speed all during the trip.

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
