Answer: 10,000(1.03)⁴ˣ
<u>Step-by-step explanation:</u>
A = P(1 + )ⁿˣ
A is the amount (new balance): <u> unknown </u>
P is the principal (amount you started with): <u> 10,000 </u>
r is the interest rate: 12% = <u> .12 </u>
n is the number of times per year it is compounded: quarterly = <u> 4 </u>
x is the number of years: <u> x </u>
A = 10,000(1 + )⁴ˣ
= 10,000(1 + .03)⁴ˣ
= 10,000(1.03)⁴ˣ
Answer:
Step-by-step explanation:
The variable x, that said the number of customer that will order a nonalcoholic beverage in a sample of n customers follows a binomial distribution. Because we have n identical and independent events with a probability p of success and (1-p) of fail.
So, the probability that x customers will order a nonalcoholic beverage is:
Where n is the size of the sample and p is the probability that a customer order a nonalcoholic beverage, so replacing the values, we get:
Now, the probability that at least 7 will order a nonalcoholic beverage is equal to:
Where:
So, is equal to:
Finally, the probability that in a sample of 10 customers, at least 7 will order a nonalcoholic beverage is equal to 0.1886
