Let n be a positive odd integer. (a) prove that there is a 1-to-1 correspondence between the divisors of n which are squareroot n. (this part does not require n to be odd.) (b) prove that there is a 1-to-1 correspondence between all of the divisors of n which are greaterthanorequalto squareroot n and all the ways of writing n as a difference s^2-t^2 of two squares of nonnegative integers. (for example, 15 has two divisors greaterthanorequalto squareroot n15, and 15 = 4^2 - 1^2 = 8^2 - 7^2.) (c) list all of the ways of writing 945 as a difference of nonnegative integers.

yeet

step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

idk bring the function back   im not smart

step-by-step explanation:

yes. we do proportions in probabilities.
