The student council at woodland middle school is planning a field trip. They polled randomly selected teachers and students and
asked what they want to eat for lunch. The result are shown in the table below. Which of the following statements is true?
2 answers:
Answer:
Option A is correct.
Step-by-step explanation:
According to results shown, we can say that option A is true.
In the burger column in above segment, we see that total number of students are 17 and total teachers are 4. Making it a total of 21.
So, ≈ 19% are teachers.
So, 19% of the polled people who preferred burgers were teachers.
Option B cannot be true as all the teachers were polled. Out of all 19% preferred burgers.
Option C is also not true because 19% was not from all the population. It was only from the teachers.
So, only option A is correct.

g(x) is basically transformed f(x). First, let's focus on f(x) graph. Notice how the graph has slope of 1 and intersect y-axis at (0,0).
Which means that our equation for f(x) is:
Now then we focus on g(x). g(x) is f(x+k). That means if f(x) = x then f(x+k) would mean substitute x = x+k in the equation.
Next, we want to find the value of k. In the slope-intercept form or y = mx+b where m = slope and b = y-intercept. Notice the g(x) graph and see that the graph intersects y-axis at (0,4). Therefore k = y-intercept = 4.
Answer
- g(x) = x+4
- Therefore the value of k is 4.
