Evaluating expressions. 3. when she was 2 months old. fiona weighed 101 pounds. she gained x pounds over the next week. write an expression to find fiona's new weight. b. evaluate the expression fiona gained 12 lbs. during that week 4. fiona's parents henry and bibs, each produce p pounds of poop every day. write an expression to find how much waste is produced in d days by the 2 hippos b. evaluate the expression henry and bibi each produce 44 pounds of poop daily. how much do they create in 14 days?

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?
