An ulcer patient has been told to avoid acidic foods. if he drinks coffee, with a ph of 5.0, it bothers him, but he can tolerate both tap water, with a ph of 5.8, and milk, with a ph of 6.9 .in order to make 10 oz of a milk-coffee drink with a ph of 5.8, how many ounces of each are required?

Ineed if you could explain and give me the answer you! this needs done

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

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?
