Step-by-step explanation:
Given : Two friends and 5 other people compete with each other for first and second chair in an orchestra.
Total people in this competition= 2+5=7
By permutation , Number of ways to arrange 7 people= 7!
Also, number of ways for two friends end up as first and second chair together= 2 × 5! [ 2 ways to arrange friends on first and second chair and 5! ways to arrange others]

Answer:
During 15 hour period, 1409.7 mg of dextrose will be delivered.
The flow rate of dextrose per hour will be 93.98 mg/hour.
Step-by-step explanation:
If a total of 3.81 liters of the solution is given over a 15 hour period.
Now, 1 liter is equivalent to 1000 ml
So, a total of 3810 ml of the solution is given over a 15 hour period.
If 100 ml of solution contains 37 mg of dextrose, then 3810 ml of the solution will contain mg of dextrose.
So, during the 15 hour period, 1409.7 mg of dextrose will be delivered.
The flow rate of dextrose per hour will be mg/hour. (Answer)
