Answer:
The system has no solution
Step-by-step explanation:
we have
----> equation A
isolate the variable y
Divide by 3 both sides
----> equation B
Compare equation A and equation B
Their slopes are equal and their y-intercepts are different
Remember that
If two lines have the same slope, then the lines are parallel
In this problem we have two different parallel lines, so, the lines don't intercept
therefore
The system has no solution
Answer: P (3 or odd) = 1/2
Step-by-step explanation:
<u>Concept:</u>
Here, we need to know the idea of probability.
Probability is a measure of the likelihood of an event to occur.
If you are still confused, please refer to the attachment below for a graphical explanation.
<u>Solve:</u>
The numbers on a dice: 1, 2, 3, 4, 5, 6
Total numbers = 6
Number of 3 = 1
Number of Odd = 3
[Since 3 is one of the odd numbers and they are overlapping, so we should subtract 1 from the number of favorable outcomes]
P (3 or odd) = Favorable / Total (refer to the attachment)
P (3 or odd) = [(1 + 3) - 1] / 6
P (3 or odd) = (4 - 1) / 6
P (3 or odd) = 3 / 6
P (3 or odd) = 1/2
