Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other. For example, x + 3 < 10.

Front

How do you graph the inequality x + 3 < 10 on a number line?

Back

You first solve for x: x < 7. Then, plot an open circle at 7 and shade to the left to indicate all numbers less than 7.

Front

What is the result of dividing -56 by 8?

Back

The result is -7.

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments.

Front

If a die is rolled 60 times and the number 4 comes up 15 times, what is the experimental probability of rolling a 4?

Back

The experimental probability is \( \frac{15}{60} = \frac{1}{4} \).

Front

What is the formula for the circumference of a circle?

Back

The circumference C of a circle is given by the formula C = πd, where d is the diameter.

Front

What is the circumference of a circle with a diameter of 10 units?

Back

The circumference is 10π units.

Front

What is a mode in a dataset?

Back

The mode is the number that appears most frequently in a dataset.

Front

In the dataset 3, 7, 7, 2, 9, 10, 3, 8, what is the mode?

Back

There is no mode because no number appears more than twice.

Front

What is the difference between a closed circle and an open circle on a number line?

Back

A closed circle indicates that the number is included in the solution (e.g., x ≤ 7), while an open circle indicates that the number is not included (e.g., x < 7).
