The answer is 8/9 i believe.
Step-by-step explanation:
the probability is always the number of desired cases over the number of all possible cases.
in our situation we have 15 cards.
that is the total possible cases when a random card is chosen.
how many desired cases do we have ?
a number NOT a multiple of 5.
how many are there ?
it is easier to say how many numbers there are being a multiple of 5 : 5, 10, 15
so, 3 numbers out of the 15 are multiple of 5.
that means
15 - 3 = 12 numbers of the 15 are NOT multiples of 5.
so, the probability to draw a card that is not a multiple of 5 is
12/15 = 4/5 = 0.8
the information about event B and even numbers is irrelevant for the question.
Answer:
What is the question?
Step-by-step explanation:
Answer:
5(9x + 2y + 10)
or
x = 0
y = -5
Step-by-step explanation:
If you are just factoring this, you will factor a 5 out from everything.
5(9x + 2y + 10)
or if you are trying to solve just isolate one of the variables and then substitute it into the original equation
45x + 10y = 50
10y = 50 - 45x
y = 5 - 4.5x
45x + 10(5-4.5x) + 50
45x + 50 - 45x + 50
x=0
45(0) + 10y + 50
0 + 10y + 50
10y + 50
10y = -50
y = -5
and it would be x = 0 and y = -5
