What is the formula to calculate population growth?

Back

The formula for population growth is P = P0(1 + r)^t, where P0 is the initial population, r is the growth rate, and t is the time in years.

What is the shape of a symmetric distribution?

Back

A symmetric distribution has a mirror image on either side of its center, often resembling a bell curve.

Front

What is the difference between skewed left and skewed right distributions?

Back

A skewed left distribution has a longer tail on the left side, while a skewed right distribution has a longer tail on the right side.

Front

What is the formula for finding the vertex of a quadratic function?

Back

The vertex of a quadratic function f(x) = ax^2 + bx + c can be found using the formula x = -b/(2a).

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.

How do you determine if a function is increasing or decreasing?

Back

A function is increasing if its derivative is positive and decreasing if its derivative is negative.
