Puzzle One Determine if the following graphs and tables show proportional
or non-proportional relationships.
To break the code each proportional relationship has a value of FIVE and
each non-proportional relationship NEGATIVE TWO.
Substitute the values into the code at the bottom to escape!

Which measure is equivalent to 110 ml? 0.0110 l 0.110 l 1.10 l 11,000 l

Which number completes the inequality? 2/3 < _ < 7/9

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?
