Answer:
Independent
Dependent
Step-by-step explanation:
Two events are independent of each other when you can mulitply them and get their intersect
we can can see that
9/20*7/10= 63/200 so these events are independent
For number 2
7/10*7/10≠ 21/40 so these events are dependent
Answer:
4
Step-by-step explanation:
Answer:
The solution for y = -1.
Step-by-step explanation:
Given:
....(1)
....(2)
So, to solve for y, first we solve for x in equation (2):

⇒
Dividing both sides by 2,
⇒
Now, substituting the value of x in equation (1):

⇒
⇒
⇒
⇒
⇒
Dividing both sides by 11,
⇒
Therefore, the solution for y = -1.
