Answer:

1/4

Step-by-step explanation:

P(1st head) = heads/ total = 1/2

P (2nd heads) =  heads/ total =1/2

P(3rd heads or tails) =  heads or tails/ total =2/2=1

Since the second flip does not depend on the first flip ( or the third on the first or second) we can just multiply the probabilities

P( head, head, head or tails) = 1/2*1/2*1

                                                 =1/4

Choose the equation that is equivalent to the equation shown below. y = 2x + 4a/6b A. x = 2x - 3by B. c = ax-by/z C. b = 6y/2x+4
Ivahew [28]

Answer:

Step-by-step explanation:

y = 2x + 4a/6b   y=(12xb+4b )/6b

6yb=12x+4a

a=(-12xb+6yb)/4=

a=3yb/2 -3xb

x=y/2-a/3b

b=2a/(3y-6x)

the solution is for every variable

1000 mg = 1 g
the prefix "milli" means "thousandth", which is why there are 1000 mg in one gram

Use that equation above as the conversion factor
3500 mg = (3500 mg)*(1 g/1000 mg) = (3500/1000) g = 3.5 g

So in short,
3500 mg = 3.5 g
