Answer:
4
Step-by-step explanation:
Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?
To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.
Here it is 4.

C. (2,1)
3(2)+7(1)=13
6+7=13
13=13
Answer:
D) 0.78, 0.029
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation 
About 78% of the US, population claims that they visit the dentist at least once a year.
This means that 
Random sample of 200 people:
This means that 
Mean and standard deviation of the sampling distribution:
By the Central Limit Theorem
Mean 
Standard deviation 
So the correct answer is given by option D.
