What is the formula for the total surface area of a rectangular prism?

Back

The total surface area (SA) of a rectangular prism is given by the formula: SA = 2lw + 2lh + 2wh, where l = length, w = width, and h = height.

What is the constant of proportionality in a linear relationship?

Back

The constant of proportionality is the ratio of the dependent variable to the independent variable in a proportional relationship, often represented as k in the equation y = kx.

How do you calculate the interquartile range (IQR) from a box plot?

Back

The interquartile range (IQR) is calculated as IQR = Q3 - Q1, where Q3 is the upper quartile and Q1 is the lower quartile.

Front

How do you solve the equation 3(y+1)=15 for y?

Back

To solve for y, first distribute: 3y + 3 = 15. Then, subtract 3 from both sides: 3y = 12. Finally, divide by 3: y = 4.

What is the definition of a box plot?

Back

A box plot is a graphical representation of a dataset that displays the median, quartiles, and potential outliers, providing a summary of the distribution.

Front

What does it mean for a graph to pass through the origin?

Back

A graph passing through the origin means that when the independent variable (x) is 0, the dependent variable (y) is also 0, indicating a proportional relationship.

Front

What is the median in a dataset?

Back

The median is the middle value when the data points are arranged in ascending order. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What is a proportional relationship?

Back

A proportional relationship is one in which two quantities maintain a constant ratio, meaning as one quantity increases, the other increases at a consistent rate.
