Answer:
y = (x - 1) / 2 (First answer choice)
Step-by-step explanation:
1) Start with f(x) = 2x + 1
2) Replace f(x) with y: y = 2x + 1
3) Interchange x and y: x = 2y + 1
4) Solve this result for y: 2y = x - 1, or y = (x - 1) / 2 (This matches the first
answer choice.)
Let x be the distance of the additional water stations from the starting line.
We want on that is 1.5 miles behind the 8-mile water station, and one that is 1.5 miles ahead. The following absolute value function describes x:
|x-1.5| = 8
Two numbers comply: x= 9.5 and 6.5.
The additional water stations will be 6.5 and 9.5 miles from the starting line.

Left is plus right is negative -11-(-15)=4 so you know 4 to the left
The <em>correct answer</em> is:
Independent.
Explanation:
The criteria for binomial experiments are:
A fixed number of trials.;
Each trial is independent of the others.;
There are only two outcomes; and
The probability of each outcome remains constant from trial to trial.
This means the outcomes are constant and independent.
