Answer:
The average rate of change is 1/4
Step-by-step explanation:
As you can see in the chart, for every four units rightward, the line goes up one unit. That means f(x) has an average rate of change of 1/4.
-2x(-4)=8x
-9(-4)=36
8x+36 is the answer

Answer:
The answer is 
Step-by-step explanation:
If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5
Thus, P(identify tap water)=0.5
The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities
- 8 of 9 people identified correctly or
- 9 of 9 people identified correctly
Since P(identify tap water)=0.5 each probabilities are the same and equal to
=
So we have
=
