(C) 18,390.65
(D) 906,784.51

Answers

The answer is B. The best way I remember rules for a problem like this is looking at the zeros. By counting the number of zeros, that helps determine how many places to move a number up or down. In this case, 1000 has 3 zeros, hence the 8 gets moved 3 places upwards. Leaving it in the hundreds place.

Which of the following functions is graphed below

Answers

Answer:

Option: C is the correct answer.

            C.   y=|x+4|-2

Step-by-step explanation:

We know that the vertex of a absolute value function or a modulus function f(x) of the type:

        f(x)=a|x-h|+k

is denoted by V such that:

          V=(h,k)

By looking at the graph of the function we see that the vertex of the function is:

                        (-4,-2)

A)

               y=|x+4|+2

The vertex of this function is:

              (-4,2)

Hence, option: A is incorrect.

B)

               y=|x-4|+2

The vertex of this function is: (4,-2).

Hence, option: B is incorrect.

D)

                 y=|x-4|-2

The vertex of this modulus function is: (4,-2)

Hence, option: D is incorrect.

C)

                y=|x+4|-2

The vertex of this function is: (-4,-2)

Also, we see that the graph of this function matches the given graph.

           Hence, option: C is correct.

There are two college entrance exams that are often taken by​ students, Exam A and Exam B. The composite score on Exam A is approximately normally distributed with mean 20.5 and standard deviation 4.9. The composite score on Exam B is approximately normally distributed with mean 1022 and standard deviation 214. Suppose you scored 27 on Exam A and 1209 on Exam B. Which exam did you score better​ on? Justify your reasoning using the normal model.

Answers

Answer: Exam A

Step-by-step explanation:

We must analyze how far are you from the mean in both cases, where the "step" that we will use to measure is the standard deviation.

In exam A, the mean is 20.5 and the standard deviation is 4.9.

If you scored a 27; then you need to see:

20.5 + 4.9 = 25.4

20.5 + 4.9 + 4.9 = 30.3

So you are within two times the standard deviation (more than the mean).

In the B exam, the mean is 1022 and the standard deviation is 214, where you scored 1209.

1022 + 214 = 1236

So in this exam, you are by one standard deviation away from the media.

With this, you can see that you did score better in exam A.

Answers

You simply analyze the bar graph.
At the weight 1 to 2 pounds, there are 2 cantaloupes.
At the weight 3 to 4 pounds, there are 5 cantaloupes.
At the weight 5 to 6 pounds, there are 8 cantaloupes.
At the weight 7 to 8 pounds, there are 9 cantaloupes.
Adding the total cantaloupes yields
2 + 5 + 8 + 9 = 24 cantaloupes
