Amedical researcher wants to determine the effect of ph (a measure of alkalinity or acidity, with pure water having a ph of 7) on the growth of a bacteria culture. the data provided to you below represents the measurements of different cultures (in thousands of bacteria) after 8 hours.

15 batches are the most you can make

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is y = 11.54

hope this : )
