The pattern first of all is divide the number by -5. (12500/ -5 = -2500, and so on) Since we know that, you divide -100 by -5 which gets you 20, then 20 by -5 which gets you -4.
The next two numbers are 20, and -4
Hope this helps!

Answer:
it saves 2.5 minutes
Step-by-step explanation:
The expected value of a random variable is the sum of products of possibilities and the probability of each.
Here, you have a probability of 0.9 of saving 5 minutes, and a probability of 0.1 of adding 20 minutes.
__
The expected value of the shortcut is ...
0.9(-5) +0.1(20) = -4.5 +2.0 = -2.5
The shortcut is expected to save 2.5 minutes on average.
_____
<em>Additional comment</em>
The probability of 0.9 comes from the 9 of 10 trips that result in a time saving.
Answer:
20%
Step-by-step explanation:
You write 32/160 and simplify it. Then when your finished simplifying, you should get 1/5. 1/5, as you should all know, is also equivalent to 20%. Because 1/5 is 20% of 100.
