Answer:
1/16
Step-by-step explanation:
First find the slope of the given line. 6x+4y=3. Isolate y. 4y=-6x+3, y=-3/2x+3/4.
The slope is -3/2. A perpendicular slope would equal the negative reciprocal of -3/2, which is 2/3.
The answer would be any line with a slope of 2/3 (ie y=2/3x-1).
To check, graph the given and derived equation.
Answer:
Ok, let's calculate the number of possible outcomes:
First, let's see the events and the number of outcomes in each event:
Drawing a card --- 4 outcomes
Rolling a number cube ---- 6 outcomes.
The total number of outcomes will be equal to the product between the number of outcomes in each individual event, this is:
C = 4*6 = 24.
Now, suppose that you have a restriction like:
"What is the probability that you have an odd number in the number cube?"
Ok, let's do the same:
Drawing a card ---- 4 outcomes (the restriction does not affect this event)
Rolling a number cube ---- 3 outcomes (because there are only 3 odd numbers)
The number of combinations is:
C' = 4*3 = 12.
Then the probability will be the quotient between the number of outcomes that meet the condition and the total number of outcomes:
P = C'/C = 12/24 = 0.5
