Answer:
The answer to your question is
Step-by-step explanation:
Data
4x - 8y = -16 ------------ (I)
x - 2y = - 8 ------------ (II)
a) Solve equation II for x
x = 2y - 8
Substitute x in equation I
4(2y - 8) - 8y = -16
8y - 32 - 8y = -16
8y - 8y = 32 - 16
0 = 16 The system has no solution because y was
cancelled.
b) When a system of equations do not have solution means that the lines are parallels and different.
Answer:
5
Step-by-step explanation:
Among the 20 digits shown, each digit appears in the list twice except 0 and 1 appear 3 times and 6 and 9 appear once. That means ...
- 1 appears 3 times
- 2 appears 2 times
So, if 1 and 2 represent red candies, there are 3+2 = 5 red candies in the simulated random sample of 20 candies.

<em>Comment on the question</em>
The simulation makes sense only if it represents taking a single candy from each of 20 packages (of unknown quantity of candies). That is, it seems we cannot answer the question, "how many red candies will be in the packages?" We can only answer the question, "how many of the simulated candies are red?"
