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.

Answer:
Well I know the formula but im not sure which option it matches to.
Step-by-step explanation:
3 x 3.5 times 1/2
+
11.4 x 10.5 times 1/2
The answer is the third option. 3 more means 3 +, the quotient of 9 and a number cubed means 9 divided by n cubed, and decreased by 2 means subtract 2.
