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. If there is an even number of values, the median is the average of the two middle numbers.

Front

How do you find the first quartile (Q1) of a data set?

Back

The first quartile (Q1) is the median of the lower half of the data set (excluding the median if the number of data points is odd). It represents the 25th percentile.

Front

What is the third quartile (Q3) in a data set?

Back

The third quartile (Q3) is the median of the upper half of the data set (excluding the median if the number of data points is odd). It represents the 75th percentile.

Front

How do you calculate the interquartile range (IQR)?

Back

The interquartile range (IQR) is calculated by subtracting the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

If Pat needs 14 sticks of pepperoni for 28 pizzas, how many sticks are needed for 1 pizza?

Back

To find the number of sticks needed for 1 pizza, divide 14 sticks by 28 pizzas: 14/28 = 0.5 sticks per pizza.

Front

What is the unit rate?

Back

The unit rate is a comparison of two different quantities when they are combined together. It is often expressed as a quantity per 1 unit of another quantity.

Front

How do you solve the inequality 7n - 1 > 76?

Back

To solve the inequality, first add 1 to both sides: 7n > 77. Then divide both sides by 7: n > 11.

Front

What does it mean to graph an inequality?

Back

Graphing an inequality involves drawing a number line and shading the region that represents all possible solutions to the inequality.

Front

What is the solution for p in the equation 3p = 144?

Back

To solve for p, divide both sides by 3: p = 144 / 3 = 48.

Front

How do you determine the total earnings based on hours worked?

Back

To determine total earnings, multiply the number of hours worked by the hourly wage.
