How do you calculate the balance of an account with compound interest?

Back

The formula is A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount, r is the annual interest rate (decimal), n is the number of times that interest is compounded per year, and t is the number of years the money is invested or borrowed.

What is the difference between linear growth and exponential growth?

Back

Linear growth increases by a constant amount over equal intervals, while exponential growth increases by a constant percentage over equal intervals.

Front

What does the function f(x) = 0.25(1.3)^x represent?

Back

This function represents exponential growth because the base (1.3) is greater than 1.

Front

What is a skewed right distribution?

Back

A skewed right distribution has a longer tail on the right side, indicating that most data points are concentrated on the left.

Front

What is a symmetric distribution?

Back

A symmetric distribution is one where the left and right sides of the distribution are mirror images of each other.

Front

What is the maximum value in a data set?

Back

The maximum value is the largest number in the data set.

Front

What is the formula for finding the maximum value of a quadratic function?

Back

For a quadratic function in the form f(x) = ax^2 + bx + c, the maximum value occurs at x = -b/(2a) if a < 0.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

What is the difference between a population and a sample in statistics?

Back

A population includes all members of a specified group, while a sample is a subset of the population used to represent the whole.
