Answer:
The average number of trials required to get the first success
Answer:
-4, 2, -1
Step-by-step explanation:
everything is being multiplied by -1/2
32 × -1/2 = -16
-16 × -1/2 = 8
So 8 × -1/2 = -4
There is a 50/50 chance Bob and Wanda will sit next to each other.
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
You would end up at (3,-1)
moving left and right is the x
moving up and down is the y
