Answer: the interest rate is 6%
Step-by-step explanation:
The formula for continuously compounded interest is
A = P x e (r x t)
Where
A represents the future value of the investment after t years.
P represents the present value or initial amount invested
r represents the interest rate
t represents the time in years for which the investment was made.
e is the mathematical constant approximated as 2.7183.
From the information given,
A = $4482
P = 1000
t = 25 years
Therefore,
4482 = 1000 x 2.7183^(r x 25)
4482/1000 = 2.7183^25r
4.482 = 2.7183^25r
Taking ln of both sides, it becomes
Ln 4.482 = 25rLn2.7183
1.5 = 25r
r = 1.5/25 = 0.06
r = 0.06 × 100 = 6%
Answer:
A. 875,000
Step-by-step explanation:
Order them by least to greatest and then find the median from there so, 700,000; 750,000; 800,000; 875,000; 1,000,000; 1,160,000; 1,180,000
875,000 is the middle man so there is your answer

Find P(A n B)
where
A = Event that the place is a city
B = Event that the place is in North
The first step is to get the sample space;
Let S represent the sample space;
The next is to list events A and B
A = City
B = North America
The next is to list common elements in A and B
The probability of A and B is calculated as follows;
Substitute and in the expression above
