10.06 miles
Step-by-step explanation:
Each lap around Steven's block is
miles.
If Steven ran six laps last week and five and a half laps this week, then the total number of laps that Steven ran is =

Step-by-step explanation:
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621

Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
