ExplanationQuestion 7. First, look on the bar chart to figure out which months had an average rainfall greater than 3 inches and then apply that information to the temperature chart. According to the bar chart, the only months that had an average rainfall exceeding 3 inches were January, February, March, October, November, and December. According to the line chart, only two of those months had average lows exceeding 30 degrees: October and November.
Hence option B is correct.Question 8. This is a multi-step problem, so you should take it one step at a time. First, determine the monthly midpoint for each month. The high in July is 78, and the low is 59, so the monthly midpoint is: 78 + 59 = 137 ÷ 2 = 68.5. Similarly, the midpoint for August is:
76 + 57 = 133 ÷ 2 = 66.5. September’s midpoint is: 68 + 50 = 118 ÷2 = 59. The average of the three midpoints is:
59 + 66.5 + 68.5 = 194 ÷ 3 = 64.7,
choice (C).
Hence option C is correct.
