To determine the standard deviation of the number of people who suffer from insomnia, you need to use the following formula:
= sqr of npq
= √10,200 people in the community x 0.6 people who suffer from insomnia x 0.91 = ?
= √10,200 x 0.6 x 0.91 = <span>√55.143 = 7.43
= 7.43</span>

Answer:
V(n)=140,000-10000n
V(7)=$70,000
Explanation:
Purchase Cost= $140,000
Value After 11 Years =$30,000
Depreciation per Year = 
The truck depreciates at a rate of $10000 per year.
Using straight-line depreciation, the value of the truck in dollars, V
The linear function of its age in years n, V(n)=140,000-10000n
When the truck is 7 years old
n=7
Truck's Value, V(n)=140,000-10000n
=140,000-(10000X7)
=140,000-70000
=$70,000
