Answer:
The theoretical probability that the first number is even and the second number is odd is .
Step-by-step explanation:
Since each dice has six sides, and there are two die, the total amount of different outcomes are or 36. The probability of getting an even number on the first roll is
or
, and the probability of getting an odd number on the second roll is also
or
, so the probability of getting an even number on the first roll and an odd number on the second roll is
.
Answer:
(4, 1)
Step-by-step explanation:
Since the first reflection is over the vertical line x=-3, the y-coordinate remains the same. The x-coordinate of A' will make the point (-3, 4) on the line of reflection be the midpoint between A and A':
(-3, 4) = (A +A')/2
2(-3, 4) -A = A' = (-6-(-7), 8 -4) = (1, 4)
The reflection over the line y=x simply interchanges the two coordinate values:
A'' = (4, 1)
Answer:
x = 5
y = 4
Step-by-step explanation:
multiply the second equation by -1 and add the first equation to eliminate "x"
_____________
Replace "y" in the first equation:
