What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does a scatterplot represent in statistics?

Back

A scatterplot is a graphical representation of the relationship between two quantitative variables.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatterplot, showing the trend of the data.

Front

What is the median in a data set?

Back

The median is the middle value when the data set is ordered from least to greatest.

Front

How does adding a new value to a data set affect the mean?

Back

Adding a new value can increase, decrease, or leave the mean unchanged, depending on the value relative to the current mean.

Front

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of the form y = ax^2 + bx + c, where a, b, and c are constants and a ≠ 0.

Front

What does the vertex of a parabola represent?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on the direction it opens.

Front

What is exponential growth?

Back

Exponential growth occurs when the growth rate of a value is proportional to its current value, leading to rapid increases.

Front

How do you calculate the number of organisms after a certain time with exponential growth?

Back

If organisms double every time period, the formula is N = N0 * 2^(t/T), where N0 is the initial number, t is the total time, and T is the doubling time.
