Answer:
625
Step-by-step explanation:
basically, half of 500 is 250 halve that you get a quater of 500 (25%)
500+125=625
X^2-2x -3 =0
a =1 b =-2 and c = -3
x = - (-2) +/- sqrt (-2)^2 - 4(1)(-3)
--------------------------------------
2(1)
x = + 2 +/- sqrt [(4) - 4(-3)]
-------------------------------
2
x = +2 +/- sqrt [4 + 12]
--------------------------
2
x = +2 +/- sqrt[16]
-------------------
2
x = +2 +/- (4)

x = 2 + 4 or 2 -4

x = 6/2 or -2/2
x = 3 or x = -1
Answer:
6 red marbles
Step-by-step explanation:
We must first find our multiplier since a sample represents a population (the whole thing).
6/2 = 3, so 3 * 2 = 6.
I will use the value of 6/2, aka 3 and use that as my divisor.
18/3 = 6.
Therefore, you would expect to have 6 red marbles.
Is it subtract by 2? So I think it would be 27,25,23,21, 19
