Answer:
$3,110.50
Explanation:
If the formula for calculating your credit card balance after t monthly payments is $15,000 x (0.986975)∧t, and t = 120 (= 10 years x 12 payments per year);
your credit card balance will = $15,000 x (0.986975)∧120 = $15,000 x 0.20737 = $3,110.50 after 10 years.
It is never a good idea to only pay the minimum monthly payment, since it takes forever to pay your credit card debt.

A. True
Explanation:
Yes! it is very true statement because due to negative views of the people against the advertising industry.
This was the reason due to which the advertising industry come up to add more tools in there advertisement through social media some of the time or through mobile phones some of the time or through the digital contents some of the time.
B. store of value
C. medium of exchange
D. measure of value
Answer: Medium of exchange.
Explanation:
The $50 is given in exchange for an iPod, therefore in the question's illustration money serves as a medium of exchange. Money as a medium of exchange means that money is needed when conducting business transactions that involves buying and selling.
Answer:
384
Explanation:
To determine the sample size needed, we can use the formula for sample size calculation in a survey:
\[ n = \frac{Z^2 \times p \times (1-p)}{E^2} \]
Where:
- \( n \) = required sample size
- \( Z \) = Z-score corresponding to the desired confidence level (for 95% confidence, Z-score is approximately 1.96)
- \( p \) = estimated prevalence rate (0.40)
- \( 1-p \) = complementary probability to the estimated prevalence rate
- \( E \) = desired margin of error (0.05, as 5% of the true value)
Plugging in the values:
\[ n = \frac{(1.96)^2 \times 0.40 \times (1 - 0.40)}{(0.05)^2} \]
\[ n = \frac{3.8416 \times 0.24}{0.0025} \]
\[ n \approx 369.7856 \]
Rounding up to ensure an adequate sample size, the required sample size should be approximately 370 schoolchildren to achieve a 95% chance of observing the prevalence rate within 5% of the true value.
The size of the sample of schoolchildren should be approximately 36880 to give a 95% chance of observing the prevalence rate to within 5% of the true value.
To calculate the required sample size, we can use the formula:
n = (Z^2 * p * (1-p)) / E^2
Where:
In this case, the desired confidence level is 95%, which corresponds to a Z-score of approximately 1.96. The estimated prevalence of malaria is 40%, which can be expressed as 0.4. The margin of error is 5%, which can be expressed as 0.05.
Substituting these values into the formula:
n = (1.96^2 * 0.4 * (1-0.4)) / 0.05^2
Simplifying the equation:
n = (3.8416 * 0.24) / 0.0025
n = 92.1984 / 0.0025
n ≈ 36879.36
Rounding up to the nearest whole number, the required sample size is approximately 36880.
