It's hard to tell from the way the question is written.
-- If he has 5 pennies, then it doesn't matter how many he lost.
He has five of them.
-- If he has 5 pennies after he lost three of them, then there are
eight now, just like there were before, but he only has 5 of them.
-- If he had 5 pennies before he lost three, then there are still
5 pennies, but he only has two of them.
Answer:
soda = 35mg
coffee = 81mg
energy = 83mg
Step-by-step explanation:
coffee + energy + soda = 199
coffee = 11 + (2 * soda)
energy = (soda + coffee) - 33
(11 + (2 * soda)) + ((soda + (11 + (2 * soda))) - 33) + soda = 199
11 + 2s + s + 11 + 2s - 33 + s = 199
22 + 6s - 33 = 199
-11 + 6s = 199
6s = 210
s = 35
soda = 35mg
c = 11 + 2s
c = 11 + 2(35)
c = 11 + 70
c = 81
coffee = 81mg
e = s + c - 33
e = (35) + (81) - 33
e = 116 - 33
e = 83
energy = 83mg
There are 13 spades in one deck, so the probability to draw a spade from the first deck is
Similarly, the probability to draw a spade from the second deck is
The probability that both events occur (so, the probability we have to draw two spades from the two decks) is the product of the two probabilities, so:
Answer:
The slope is 4/5 i dont know unit rate though, hope this helps:)
