Front

What is the median of the data set {3, 5, 5, 7, 9}?

Back

The median is 5.

Front

What is the mean of the data set {3, 5, 5, 7, 9}?

Back

The mean is 5.

Front

What is the range of the data set {3, 5, 5, 7, 9}?

Back

The range is 6 (9 - 3).

Front

How do you find the x-intercept of the equation 4x + 3y = 6?

Back

Set y = 0 and solve for x: 4x = 6, so x = \frac{3}{2}.

Front

What does a histogram represent in data analysis?

Back

A histogram represents the frequency distribution of a data set.

Front

What is the slope of the line represented by the equation y = -x + 2?

Back

The slope is -1.

Front

How do you determine the total number of students represented by a histogram?

Back

Sum the heights of the bars in the histogram.

Front

What is the formula for calculating the mean of a data set?

Back

Mean = (Sum of all values) / (Number of values).

Front

What is the definition of an x-intercept?

Back

The x-intercept is the point where a graph intersects the x-axis (y = 0).

Front

How do you find the median of a data set?

Back

Arrange the data in ascending order and find the middle value.
