What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is given by the formula: Area = base × height.

Front

If the area of a parallelogram is 90 square inches and the base is 15 inches, what is the height?

Back

Height = Area / base = 90 / 15 = 6 inches.

Front

In a right triangle, if one angle measures 70 degrees, how do you find the other acute angle?

Back

The sum of angles in a triangle is 180 degrees. Therefore, the other acute angle = 180 - 90 - 70 = 20 degrees.

Front

What is the median in a box-and-whisker plot?

Back

The median is the middle value of the data set when arranged in order. It divides the data into two equal halves.

Front

What does a line perpendicular to another line represent in terms of slopes?

Back

Two lines are perpendicular if the product of their slopes is -1. If one line has a slope of m, the perpendicular line will have a slope of -1/m.

Front

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

Back

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

Front

How do you determine the line of best fit from a scatterplot?

Back

The line of best fit minimizes the distance between the line and all the points in the scatterplot, often found using linear regression.

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

How do you calculate the height of a parallelogram if the area and base are known?

Back

Height = Area / base.

Front

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is 90 degrees, and the sum of the other two acute angles is 90 degrees.
