If we use some relative math to draw conclusions, we can see that adding the totals for each month gets us to around 9,000. However, the prompt tells us that the total consumption of farmed animals was 9 billion. So, we need to multiply each of our values by one million (1,000,000) to achieve this total. Thus, the y axis gives us the number of animals in millions.

In this case, if we add 5 to each of the numbers in the table above, the dispersion of the set remains the same (all values remain the same distance from one another that they started out at, and just shift 5 up on the number line). However, if I add 5 to each value, the sum of my values will increase, and thus the average/mean (the sum of numbers/number of numbers) will also increase. Thus, “mean” is our correct answer.

Since the “C” intercept refers to the constant in the linear equation expressed by this graph, it doesn’t make sense for the intercept to refer to a charge “per” any other unknown, whether that unknown is miles or quarter miles. We know that the intercept cannot refer to miles driven, as that has been expressed to us as “M” in this linear relationship. The “C” intercept can, however, refer to an up-front fee assessed regardless of miles driven, as is expressed in our correct answer, “The initial fee of the taxi, regardless of miles driven.”

Some important things to consider from the description in this question are that: 1) Lauren started the race as fast as she could run, meaning that all the way at the left hand side of the graph is where the line for her speed should be at its highest. 2) She slowed during the middle portion of the race and then got even slower toward the end, so there shouldn't be any peaks toward the right half of the graph - everything should be flat or pointed downward. Only one graph starts highest on the left and avoids peaks on the right half, so you have your correct answer.

Some important things about this situation should stand out to you. For one, there should be a sharp drop in the amount of money in Charlie's account before you see a steeper slope in his increase: he makes money at one job, then loses money on the window, then continues that same increase slope before his slope ever increases. So a graph such as the following that has an increase in slope before it ever decreases is incorrect:

You then need him to recover his savings slowly at first, and then with a sharp increase in his savings rate as he doubles his hours.  And you need him to have only two decreases in his savings: the window, then after some recovery the video game purchase.

Only one graph accounts for these: a slow growth then a decrease, then a slow growth then a steeper slope, then one big drop. This is your correct answer:

The correct answer is $11. He would make the most money on the day he sold the most cups of lemonade. On Thursday, he sold 22 cups. Since each cup costs $0.50, he made $11 that day.

According to the graph, he sold 4 cups on Friday and 13 cups on Saturday. Thus, the fraction of cups sold on Friday compared to Saturday is .

According to the graph, he sold 22 cups on Thursday and 4 cups on Friday.

The graph shows an increase (a positive slope) from Monday to Tuesday and Friday to Saturday. However, there is a sharp decline from Thursday to Friday.

According to the graph, the number of schools decreased from 1960 to 1970 (13 to 9) and 2000 to 2010 (17 to 15). From 1930 to 1940, a new school was added.
