A box contains 19 green marbles and 19 white marbles. If the first marble chosen was a white marble, what is the probability of choosing, without replacement, another white marble? Express your answer as a fraction or a decimal number rounded to four decimal places.

0.4865  or 18/37

Step-by-step explanation:

You first pick would have had the probability of 19/38.

Your second pick would have the probability of 18/37 if you do not put the first marble back.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

i'm pretty sure the answer is a. decreases with increase in
