Alandscaper charges a one-time fee of $70 plus $45 for each hour on the job. if t is the number of hours on the job and f is the total fee for the work done, then the variables are related by the equation f = 45t + 70. which variable is the independent variable?

a. t b. f c. there is no relationship between the variables.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual? (b) you like neither of them. (c) you like exactly one of them. (d) redo () if a song can be replayed before all 8 songs are played.
