It would be the first answer, the graph if g(x) is the graph of f(x) translated 2 units left
This is because the +2 is in the parentheses with the x which makes it move left or right and because it’s positive you would do the opposite and more it left
"nine times out of ten" means we have 9/10 = 0.90 = 90% confidence interval.
The center of each interval is 0.80 as this is the mean test score. The margin of error is 0.06 from the statement "within 6% of...". Put another way, the teacher is basically saying that they are 90% confident to find a test score between 74% and 86%
This is because
0.8 - 0.06 = 0.74
0.8 + 0.06 = 0.86
So that's why the confidence interval is (0.74, 0.86)
Answer: 
Step-by-step explanation:
For this exercise it is necessary to remember that the area of a circle can be calculated with the following formula:

Where "A" is the area of the circle and "r" is the radius of the circle.
In this case, based on the information given in the exercise, you know that the circular plate has the following radius:

Therefore, knowing the radius, you can substitute them into the formula and finally, you must evaluate in order to calculate the area of the plate (Remember that you must use 3.14 for
).
Then, you get that this is:
