B) 40,000. the first 2 is 20,000. the second 2 is 2. 20,000 times 2 is 40,000
Answer:
The number of favorable outcomes is 5
Step-by-step explanation:
<u><em>The correct question is</em></u>
How many favorable outcomes are expressed in the fraction 5/12
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the event space is the number of outcomes in the event you are interested in or the number of favorable outcomes
The size of the sample space is the total number of possible outcomes
In this problem we have

therefore
The number of favorable outcomes is 5
The total number of possible outcomes is 12
Answer:
A. x = -5/6 and x = 1/2.
Step-by-step explanation:
12x^2 + 4x - 5 = 0
Use the 'ac' method to try to factor this:
Consider the above highlighted numbers:
12 * -5 = -60.
Now we need 2 numbers whose product is -60 and whose sum is +4.
They are -6 and +10, so we replace the + 4x by -6x + 10x:
12x^2 - 6x + 10x - 5 = 0 Now factor by grouping:
6x(2x - 2) + 5(2x - 1) = 0 The 2x -1 is common, so:
(6x + 5)(2x - 1) = 0
So x = -5/6 and x = 1/2.
Answer:
x=-1, y=2
Step-by-step explanation:
Plug the y=-2x into the second equation in place of the y to get 4x+10(-2x)=16
Simplify this to 4x-20x=16 then to -16x=16
Divide both side by -16 to get x=-1
Plug x=-1 into the first equation to get -2(-1)=y
Simplify to get y=2
