Please check and tell me the answers for the 5.8.7 - Quiz: Exploring Scatter Plots Quiz Part 1 of Connexus I need assistance.
1. Two graphs displaying the number of As received at Bridgeport Middle School. The left graph is labeled A’s at Bridgeport Middle School. The x-axis is labeled Grade. The y-axis is labeled Number of Students and goes from 10 to 90 in increments of 10. The 6th grade bar goes to 47. The 7th grade bar goes to 40. The 8th grade bar goes to 41. The right graph is labeled A’s at Bridgeport Middle School. The x-axis is labeled Grade. The y-axis is labeled Number of Students and goes from 40 to 47 in increments of 1. The 6th grade bar goes to 47. The 7th grade bar goes to 40. The 8th grade bar goes to 41.
The graphs above show the number of students receiving A’s in each grade at Bridgeport Middle School. Which statement is true?
A. The scale on the first graph does not distort the lengths of the bars.
B. The second graph shows greater changes in the number of A’s than the first graph.
C. The two graphs use completely different data.

My Answer is C.
2. The graph above shows the cost of a large cheese pizza at three different restaurants. What is the best way for this graph to be adapted to more accurately show the information?

B. The graph should be redrawn with the vertical axis beginning with $0.
C. The bars should be much narrower.
D. There should be no space between the bars.
My answer is B.
