Answer:
$28,188.46
Step-by-step explanation:
The formula you need is:
Where A(t) is the amount after the compounding, P is the initial investment, r is the interest rate, n is the number of compoundings per year, and t is the time in years. We are looking for A(t). P is $14,250; r in decimal form is .0525; n is 52 since there are 52 weeks in a year; t is 13 years. Filling in:
Simplifying inside the parenthesis and the exponential multiplication:
Raising the number in parenthesis to the power of 676 gives us:
A(t) = 14,250(1.978137432)
Multiplying then gives us $28,188.46
Answer:
the answer is x= 5 and y = 1.5
The second, third, and fourth answer should be correct and the most logical for this question :P
Answer:
Step-by-step explanation:
a. Our random variable follows a binomial distribution which is defined as:
where 
is the probability of success, 
the sample size and 
the random variable.
-Given that 
, 
what's 
Hence, the probability of exactly two is 0.2107
b. The probability that more than two adults are more likely to make purchases during a sales tax holiday is given by:
Hence the probability of more that two adult purchases is 0.6727
c. The probability that the number of adults who say they are more likely to make purchases between 2 and 5 is obtain by summing the the probabilities
p(x=2)+p(x=3)+p(x=4)+p(x=5).
-From b above, we already have p(x=2)=0.2107. Therefore:
-Hence the probability of between two and five is 0.8157
