Question

A scientist is growing bacteria in a petri dish. The scatter plot below shows the number of bacteria in the dish over time.

A graph is shown.A graph of 'Time' in days from 0 to 12 on the x axis and 'Number of Bacteria' from 0 to 400 on the y axis is shown. Nine points are plotted beginning at 1 comma 50 increasing to approximately 9 comma 325. Points between these two include approximately 2 comma 110, 3 comma 80, 4 comma 120, 5 comma 175, 6 comma 225, 7 comma 240, and 8 comma 275.

If this growth trend continues, approximately how many bacteria would be in the petri dish on day 10?

Answer 1

this is math my bad i will give free money to who can answer

Answer 2

ever think of typing points as, say, (4,120)?
These points are not too far off a straight line.
There are several handy linear regression calculators online you can use to get the line of best fit.
Then just plug in x=10 for that equation.

But, since the differences are approximately 50 for each point, and the overall slope of the line is 325/9 = 36.1

Maybe just guess y(10) = 370 or so

Answer 3

I feel like someone is gonna answer in like years from now so hello! this is anne from the past.. did you get your answers you were looking for? i didn't.. D:

Answer 4
