Given:
2,000 square kilometers
decreases by 6% per year
12 years.
f(x) = P(1+r)^x
The fact that the term decreases is used, (1+r) will become (1-r)
f(12) = 2,000(1-0.06)^12
f(12) = 2,000(0.94)^12
f(12) = 2,000(0.4759)
f(12) = 951.80
Answer is:
f(x) = 2,000(0.94)^x, 952 square kilometers.
His average speed is 40mph you get your answer by dividing 80 by 2, or or you could do what is half of 80 which is 40. So Mr.Campbell average speed is 40mph
$ 325.2372 will be charged on Patrick's Visa card.
<u><em>Explanation</em></u>
The regular price of each tire is $95.99 and the discount amount is $20 per tire.
So, the selling price of each tire will be: 
and the total <u>selling price of 4 tires</u> 
The sale tax is 7%. So, the <u>amount of sale tax</u> 
dollar
So, the total charge on Patrick's Visa card will be: 
dollar

We will check if the elevator can hold 10 man
X~(177,32^2)
n= 10
P(SigmaX>172)
SigmaX~(177*10,(32^2)*10)
SigamX~N(1770, 101.19^2)
P(SigmaX>172*10=1720) =Z=(1720-1770)/101.19
Z = -0.49
From Z table Z=-0.49
P(Z=-0.49) = 0.3121 (probability they will not overload)
1- 0.3123 = 0.6879 = 68.79%
The elevator is not safe, the probability to be more the 172 is 68.79%, high probability they could not make it.
