Answer:
Step-by-step explanation:
Since the company wants to survey 500 customers by the countries visited, the number of samples from each country will be proportional to the number of customers.
For UK, Number of Samples
For France, Number of Samples
For Spain, Number of Samples
For Italy, Number of Samples
The completed table therefore is:
The exponential to describe $100 at 2% interest, compounded annually, for x years is
Given that $ 100 at 2 % interest , compounded annually for "x" years
<em><u>The formula for compound interest, including principal sum, is:</u></em>
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for
Here in this sum,
P = $ 100
number of years = x
Here given that compounded annually , so n = 1
Let "y" be the amount after "x" years
Substituting the values in formula we get,
Thus the exponential to describe is
