Susan wants to find an estimate for the number of fish in a lake. On Monday she catches 77 fish and marks each with a non-harmful dye.
She then returns those fish to the lake.
On Tuesday Susan catches 400 fish and notes down how many had dye on them.
Using her sampling information, Susan estimates the total number of fish in the lake to be
550.
How many of the fish Susan caught on Tuesday must have been marked with the dye?

I hate you I am so sick of you oh my lord

35

Step-by-step explanation:

x/300=56/480 x = 35

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
