Solution Steps

Step 1: Understanding pH Scale

The pH scale ranges from 0 to 14, where a lower pH value indicates a more acidic solution, a pH of 7 is neutral, and a higher pH value indicates a more basic (alkaline) solution. Therefore, to arrange pH values from the most basic to the most acidic, we should list them from the highest to the lowest.

Step 2: Analyzing Each Option
  • Option a: \(1, 3, 8, 11, 14\) - This sequence is from acidic to basic.
  • Option b: \(2, 5, 7, 10, 11\) - This sequence is from acidic to basic.
  • Option c: \(14, 10, 7, 4, 1\) - This sequence is from basic to acidic.
  • Option d: \(14, 10, 7, 1, 3\) - This sequence is from basic to acidic, but the last two values are not in order.
  • Option e: \(7, 10, 5, 3, 2\) - This sequence is not in order from basic to acidic.
Step 3: Identifying the Correct Sequence

The correct sequence from the most basic to the most acidic is the one that starts with the highest pH value and ends with the lowest. From the analysis, option c (\(14, 10, 7, 4, 1\)) is the only sequence that correctly follows this order.

The accompanying table gives the distance from a particular city to seven other cities (in thousands of miles) and gives the time for one randomly chosen, commercial airplane to make that flight. Do a complete regression analysis that includes a scatterplot with the line, interprets the slope and intercept, and predicts how much time a nonstop flight from this city would take to another city that is located 3000 miles away. Does it seem that the trend is linear, or is there a noticeable curve? Find the equation for predicting time (in hours) from miles (in thousands). Predicted Time = 1.5 + 0.5 Thousand Miles
