In which set are the numbers arranged in ascending order? (1 point)

3.25 * 10 ^ - 4 1.25 * 10 ^ - 3 2.25 * 10 ^ - 3 3.25 * 10 ^ - 3

0.000325, 0.00225, 0.00125, 0.00325

3.25 * 10 ^ - 3 2.25 * 10 ^ - 3 3.25 * 10 ^ - 4 1.25 * 10 ^ - 3

0.00125, 0.00225, 0.000325, 0.00325

To determine which set arranges the numbers in ascending order, we need to convert the scientific notation to decimal notation for each entry and then compare the values.

  1. First set:
  • \(3.25 \times 10^{-4} = 0.000325\)
  • \(1.25 \times 10^{-3} = 0.00125\)
  • \(2.25 \times 10^{-3} = 0.00225\)
  • \(3.25 \times 10^{-3} = 0.00325\)

This gives us the decimal values: \(0.000325, 0.00125, 0.00225, 0.00325\)

  1. Second set:
  • \(3.25 \times 10^{-3} = 0.00325\)
  • \(2.25 \times 10^{-3} = 0.00225\)
  • \(3.25 \times 10^{-4} = 0.000325\)
  • \(1.25 \times 10^{-3} = 0.00125\)

This gives us the decimal values: \(0.00325, 0.00225, 0.000325, 0.00125\)

Now, arranging the decimal values from both sets in ascending order:

For the first set:

  • \(0.000325 < 0.00125 < 0.00225 < 0.00325\) (Correct ascending order)

For the second set:

  • \(0.00325 > 0.00225 > 0.000325 < 0.00125\) (Not in ascending order)

Thus, the first set \(0.000325, 0.00125, 0.00225, 0.00325\) is in ascending order.
