At time t=0 hours, a tanks contains 3000 litres of water.
water leaks from the tank.
at the end of every hour there is a x% less water in the tank than at the start of the hour.
the volume of water, in litres, in the tank at time t hours is vt.
given that
vt=k^tv0
v2=2881.2
work out the value of k and the value of x

The probability that a u.s. resident has traveled to canada is 0.18 and to mexico is 0.09. a. if traveling to canada and traveling to mexico are independent events, what is the probability that a randomly-selected person has traveled to both? (page 109 in the book may ) b. it turns out that only 4% of u.s. residents have traveled to both countries. comparing this with your answer to part a, are the events independent? explain why or why not. (page 119 may ) c. using the %’s given, make a venn diagram to display this information. (don’t use your answer to part a.) d. using the conditional probability formula (page 114 in the book) and the %’s given, find the probability that a randomly-selected person has traveled to canada, if we know they have traveled to mexico.
