You use y=mx+b i think to find the total cost
1. Factor out 9a^2 from the expression
9a^2 x(9x+y) - 90bx - 10by
2. Factor out -10b from the expression
9a^2 x(9x+y) - 10b x(9x+y)
3. Factor out 9x + y from the expression
(9x+y)x(9a^2 - 10b)
Solution: (9x+y)x(9a^2 - 10b)
Answer:
True
Step-by-step explanation:
If two events X and Y are mutually exclusive,
Then,
P(X∪Y) = P(X) + P(Y)
Let A represents the event of a diamond card and B represent the event of a heart card,
We know that,
In a deck of 52 cards there are 4 suit ( 13 Club cards, 13 heart cards, 13 diamond cards and 13 Spade cards )
That is, those cards which are heart can not be diamond card,
⇒ A ∩ B = ∅
⇒ P(A∩B) = 0
Since, P(A∪B) = P(A) + P(B) - P(A∩B)
⇒ P(A∪B) = P(A) + P(B)
By the above statement,
Events A and B are mutually exclusive,
Hence, the probability of selecting a 4 of diamonds or a 4 of hearts is an example of a mutually exclusive event is a true statement.
Well your suppose to divide 10/32=3.2 then ur suppose to times 3.2 with 72 then it= 2304
I think the answer is 245.14
