hope this helps
Step-by-step explanation:
Answer:
<u>The standard deviation of the uniform distribution is:</u>
<u>U(3, 12)</u>
- σ = (12−3)/√12 = 9/√12 = 2.5981
<u>U(80, 250)</u>
- σ = (250−80)/√12 = 170/√12 = 49.0748
<u>U(4, 93)</u>
- σ = (93−4)/√12 = 89/√12 = 25.6921
The choice which describes the solution is; The solution is 5, which represents the number of miles she runs each day.
<h3>Word problems</h3>
According to the task content;
- The total distance covered running and cycling per day is; 20miles
- Additionally, she cycles a total of 105 miles each week.
From the statement above; it follows that;
The number of miles she cycles per day since 7 days make a week is;
Hence, it follows that the equation; (15+r) = 20 represents the daily distance covered by cycling and running.
On this note, it follows that;
Hence, The solution is 5, which represents the number of miles she runs each day.
