Question

According to the line graph above, between which two consecutive years was there the greatest change in the number of 3‑D movies released?</span

- 2003 – 2004
- 2008 – 2009
- 2009 – 2010
- 2010 – 2011

## The correct answer is: 2010 – 2011

### A line graph is a type of chart used to display data that changes over time. We plot line graphs using various points joined by straight lines and we also call this a line chart or line plot.

The dark spots on the graph indicate data points. A data point on a line graph shows the quantity/number that resembles a particular time in the x-axis.

For finding the solution of the given problem we have to find the change in number of 3-D movies released between all consecutive years.

It can be found by first estimating the number of 3-D movies released for each of the two years and then finding the positive difference between these two values.

- Between 2003 and 2004, change is 2 − 2 = 0 movie
- Between 2008 and 2009, change is 20 − 8 = 12 movies;
- Between 2009 and 2010, change is 26 − 20 = 6 movies;
- and between 2010 and 2011, change is 46 − 26 = 20 movies.

Therefore, for the pairs of consecutive years in the choices, the greatest increase in the number of 3-D movies released occurred during the time period between 2010 and 2011.

Therefore, options A, B, and C are incorrect.

Between 2010 and 2011, approximately 20 more 3-D movies were released. The change in the number of 3-D movies released between any of the other pairs of consecutive years is smaller than 20.

- Between 2003 and 2004, change is 2 − 2 = 0 movie
- Between 2008 and 2009, change is 20 − 8 = 12 movies;
- Between 2009 and 2010, change is 26 − 20 = 6 movies;
- and between 2010 and 2011, change is 46 − 26 = 20 movies.

The formula above is used to estimate the ideal quantity, *Q*, of items a store manager needs to order given the demand quantity, *d*; the setup cost per order, *K*; and the storage cost per item, *h*. Which of the following correctly expresses the storage cost per item in terms of the other variables?

**Note:**

Whenever there is an equation with a square root involved, first we try to remove that square root to get a clear picture of the equation. It is easier to operate on an equation with no square roots or log or inverse.

### In the *xy*-plane, the point (2, 6) lies on the graph of where *k *is a constant. Which of the following points must also lie on the graph?

**Note: **

Whenever there is an unknown constant in the given equation, we must always try to find the value of that constant first with the help of the given conditions. Another way to solve this question is; observe that the equation can be written as x y = k , that is, the product of the x co-ordinate and y co-ordinate always remains a constant. As the point (2, 6) satisfies it, we get that constant to be 12. So we check for which of the points in the options, the product of x co-ordinate and y co-ordinate is 12.
