Website Resource Loading Issues
- Message indicates problems with loading external resources on a website.
- Suggests possible issues related to web filters preventing access to necessary domains.
- Encourages users to check and unblock specific domains: *.kastatic.org and *.kasandbox.org.
- Highlights the importance of unblocking domains for proper functionality of web-based resources.
- External resources are often crucial for enhancing website performance and user experience.
Calculating Percentages
- A percentage quantifies a number as a fraction out of 100.
- To determine a percentage of a number:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ] - Converting a percentage to a decimal involves dividing by 100:
[ \text{Decimal} = \frac{\text{Percentage}}{100} ]
Percentage Increase/Decrease
-
Percentage Increase measures growth:
[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \right) \times 100 ] -
Percentage Decrease measures a reduction:
[ \text{Percentage Decrease} = \left( \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \right) \times 100 ]
Rates of Change
- A rate of change reflects how a quantity alters concerning another quantity.
- Average Rate of Change is calculated as:
[ \text{Rate of Change} = \frac{\text{Change in Value}}{\text{Change in Time}} ] - Widely applied across fields like economics, physics, and biology to track trends over time.
Applications of Percentages
- Used in Finance for calculating discounts, sales tax, and price markup.
- In Statistics, percentages analyze survey data, proportions, and demographic studies.
- Health statistics utilize percentages for measuring incidence and prevalence.
- In Education, percentages assist in grading, GPA calculations, and assessing performance metrics.
Interest Rates
- Interest rates represent the percentage earned or paid on a loan/investment over time.
-
Simple Interest is calculated with:
[ \text{Simple Interest} = \text{Principal} \times \text{Rate} \times \text{Time} ] -
Compound Interest grows on both principal and accumulated interest, calculated as:
[ A = P \left(1 + \frac{r}{n}\right)^{nt} ]- In this equation, ( A ) = total amount, ( P ) = principal, ( r ) = annual interest rate, ( n ) = frequency of interest application, ( t ) = number of periods.
- Interest rates are crucial for making informed financial decisions regarding investments, loans, and savings.
