Which problem situation can be represented by the algebraic model y = 120 - 3x? Olivia is preparing goody bags for 3
kindergarten classes. She has 120 little
toys to put in the bags. What is y, the
number of bags she fills, if she put x toys in
each bag?
Thomas is cutting 3-inch pieces off a 120-
inch long rod. What is the length of the rod,
y, after he has cut off x pieces?
Hilary has 120 pictures to put in her photo
album. What is y, the number of pages she
will fill, if she puts 3 pictures on each
page?
Robbie received $120 for his birthday. He
wants to purchase music downloads for his
MP3 player. What is y, the amount he will
spend if each download is x dollars plus a
one time service fee of $3.00?

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
