Suppose you have $100, which you can invest with a 10% return each year. after one year, its 100 x 1.1 = 110 dollars, and after two years its 100 x 1.1 x 1.1 =121. add code to calculate how much money they end up with after 7 years and print the results.

i believe the question is looking for the calculation to involve exponentiation and modulo.

this code is to be written out in python but if you can't that's fine any would be appreciated

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
