Answer:
There is no question stated. If one assume the question is "Does the probability of picking the same color pen change after the first try?," the answer is "No."
Step-by-step explanation:
When the pen is replaced, the probability reverts back to the original value:
There are 7 pens:
5 Blue
2 Red
The probability of picking a red or blue pen on the first try is:
Red = 2/7
Blue = 5/7
When the pen is replaced, the probabilities return to the original values.
Answer:
C
Step-by-step explanation:
Parallel and opposite sides of a parallelogram are equal. Hence, we can say:
x + 30 = 2x - 10
and
2y-10 = y +10
Solving first one, we get:
x + 30 = 2x - 10
30+10 = x
x = 40
Also
2y - 10 = y + 10
y = 10 + 10
y = 20
Now, z = x - y, so
z = 40 - 20 = 20
Answer C is right.
Answer:
The answer is B because x = 4 so 12x4-3=45
