Alarge aquarium of water is being filled with a hose. due to a problem, the sensor does not start working until some time into the filling process. the sensor starts its recording at the time zero minutes. the sensor initially detects the tank has 225 liters of water in it. the hose fills the aquarium at a constant rate of 15 liters per minute. what will the sensor read at the time 5 minutes? later, someone wants to use the data to find the amount of water at times before the sensor started. what should the sensor have read at the time -7 minutes?

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?

Katie wants to collect over 100 seashells. she already has 34 seashells in her collection. each day, she finds 12 more seashells on the beach. katie can use fractions of days to find seashells. write an inequality to determine the number of days, dd, it will take katie to collect over 100 seashells.
