Answer:
142 years 3 months
Step-by-step explanation:
Let us assume the investment is made using a simple interest
Given data
Principal p= $1200
Rate r= 7.5%= 7.5/100= 0.075
Final amount A= $14000
Time t=?
The Simple interest formula is expressed as
A= p(1+rt)
Substituting we can solve for t
14000= 1200(1+0.075t)
14000= 1200+90t
14000-1200=90t
12800= 90t
t= 12800/90t = 142.22 years
The time required to get a total amount, principal plus interest, of $14,000.00 from simple interest on a principal of $1,200.00 at an interest rate of 7.5% per year is 142.22 years (about 142 years 3 months).
Answer:
Step-by-step explanation:
We use trigonometry to find the angle of elevation.
From the diagram, the angle of elevation of the sun is 
Recall the mnemonics SOH CAH TOA.
Therefore the angle of elevation of the sun is

<span>To solve this we would need to find the bottom 10% z-score and find c such that Pr(X<c)=0.1. We find that c = -1.2815 using normal distribution. The cutoff salary for teachers in the bottom 10% would be X=26000 + 5000 x (-1.28155) or 19,592.24.</span>
