Friday the 6th Practice

Front

Find the average of the numbers: 99, 107, 87, 103, and 84.

Back

The average is calculated by summing the numbers and dividing by the count. (99 + 107 + 87 + 103 + 84) / 5 = 96.

Front

Four times a number, increased by 6 is greater than 22. What is the inequality?

Back

The inequality is 4x + 6 > 22.

Front

Calculate: 15 + 7 × 2 – 11 + 35.

Back

Using the order of operations (PEMDAS), the answer is 53.

Front

Evaluate: (9 + 23) ÷ (5 - 3).

Back

The answer is 16.

Front

Simplify: 4(2+3)² - 2(6-4)².

Back

The simplified result is 92.

Front

What is the formula for calculating the average of a set of numbers?

Back

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

Front

Define the order of operations in mathematics.

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What does the term 'inequality' mean in mathematics?

Back

An inequality is a mathematical statement that indicates one quantity is larger or smaller than another, using symbols like >, <, ≥, or ≤.

Front

What is the result of 7 × 2?

Back

The result is 14.

Front

What is the value of 6 - 4?

Back

The value is 2.
