The following chart shows the quarterly revenue for companies A, B, C, and D. Which company experienced the largest percentage increase in revenue from Q1 to Q2?

Answer: Company D

To find the percentage increase, use the formula: ((Q2 Revenue - Q1 Revenue) / Q1 Revenue) * 100. Company A: ((350-300)/300)*100 = 16.67% Company B: ((420-400)/400)*100 = 5% Company C: ((280-250)/250)*100 = 12% Company D: ((200-150)/150)*100 = 33.33%. Company D had the highest percentage increase.

A market research firm compiled the following pie chart illustrating the preferred social media platforms of a sample of 500 users. How many more users preferred Platform B over Platform D?

Answer: 50 users

First, calculate the number of users for each platform. Platform B: 35% of 500 = 0.35 * 500 = 175 users. Platform D: 25% of 500 = 0.25 * 500 = 125 users. The difference is 175 - 125 = 50 users.

The line graph below shows the monthly average temperature for City X over a year. During which of the following periods was the rate of temperature increase the greatest?

Answer: March to May

The rate of increase is represented by the steepness of the line segment. Visually inspecting the graph, the line segment from March to May has the steepest positive slope, indicating the most rapid increase in average temperature.

The stacked bar chart displays the sales distribution by product category (Electronics, Apparel, Home Goods) for two different stores. Which of the following statements can be concluded from the chart?

Answer: Store 2 has a higher proportion of its total sales from Home Goods than Store 1.

By visually comparing the proportion of the 'Home Goods' segment in each bar relative to the total height of the bar, it's clear that this category makes up a larger percentage of Store 2's total sales than Store 1's. The other statements cannot be definitively concluded without specific values; for example, we don't know the exact sales figures to compare total sales or category sales directly.

A scatter plot shows the relationship between hours studied and exam scores for a group of students. The plot displays a positive linear correlation. What is the most logical interpretation of this relationship?

Answer: There is a general trend that students who study for more hours tend to achieve higher exam scores.

A positive linear correlation indicates that as one variable increases, the other variable also tends to increase. In this context, it means that more hours of study are generally associated with higher exam scores.

The provided area chart shows the number of active users over 6 months for two mobile applications, App X and App Y. In which month was the absolute difference in active users between the two apps the smallest?

Answer: Month 2

The absolute difference is the vertical distance between the two lines on the chart. By visually inspecting the graph, the lines for App X and App Y are closest together in Month 2, indicating the smallest difference in the number of active users.
