Answer:
His time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
Step-by-step explanation:
With an standard deviation of 3.2 minutes, it is clear that the maximum time taken by Roman to complete his run of 3 miles would be
Average time + standard deviation = 24.7 minutes + 3.2 minutes = 27.9 minutes
The minimum time taken by Roman to complete his run of 3 miles would be
Average time - standard deviation = 24.7 minutes - 3.2 minutes = 21.5 minutes
Hence, his time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
914 070 in two significant figures will be rounded off to: 910,000.
<h3>How to Rounding Up a Number to 2 Significant Figure</h3>
- Significant figures are non-zero digits or digits before a decimal.
- To round up to 2 significant figure, if the digit we are rounding off is more than 5, we round up, if it is less than 5, we round down.
Thus, given 914 070.
The digit, 4, is less than 5, therefore, we will round down.
Therefore, 914 070 in two significant figures will be rounded off to: 910,000.
