4. If Nick goes swimming 7 times, what would he need to pay with each payment plan? Which is the best payment method for him?
5. If Nick goes swimming 9 times, what would he need to pay with each payment plan? Which is

6. If Nick goes swimming 13 times, what would he need to pay with each payment plan? Which is
the best payment method for him?
7. Nick's youth group has 25 regular students that attend weekly get togethers. They saved up
enough money for each person to go swimming 15 times each with the daily pay plan. After they
saved that amount, they found out they can use the early pay plan and save money. They plan to
donate their savings to the church since it's in need of a new sound system. How much money
will they be able to donate with the savings from all 25 youth? (Please show all your work for full

Which number line represents the solution set for the inequality - x 24?

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers

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?
