Choose an equation that would be used to solve 0 = -x2 + 10x – 8
Answer: (x-5)^2=17
Answer: 3/8
Step-by-step explanation:
Since it is a fair coin, then generally, P(Head) = P(Tail) = ½
And since we've been asked to find the probability that the number of heads in the first two tosses be equal to the number of heads in the second two tosses, tossing a fair coin four times, the possible outcomes of having equal number of heads in first two tosses and second two tosses becomes:
[HHHH] or [HTHT] or [THTH] or [TTTT] or [HTTH] or [THHT]
=[½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½]
=1/16 * 6
=6/16
=3/8.
Answer: 75% off the original price.
Step-by-step explanation:Say an item is $100. 50% off $100 is of coarse $50.
Now 50% off that price is $25.
So the new price is now $25 which is 75% off.
