What are Linear Pair, Supplementary Angles, and Adjacent Angles?

Back

Linear Pair: Two adjacent angles that form a straight line. Supplementary Angles: Two angles whose sum is 180 degrees. Adjacent Angles: Two angles that share a common side and vertex.

How do you predict the number of students based on a sample?

Back

To predict the number of students, use the formula: (Number of students in sample / Total students surveyed) * Total students in school. For example, if 150 students were surveyed and 54 spend an hour, then (54/150) * 900 = 324.

How many outcomes are possible for a large or medium 1-topping pizza with 4 toppings?

Back

There are 8 possible outcomes. For each size (large or medium), you can choose 1 topping from 4 options: 4 (large) + 4 (medium) = 8.

Front

What is the MODE in a set of scores?

Back

The MODE is the number that appears most frequently in a data set.

Front

How do you write an equation to model lengths?

Back

To model lengths, set the expressions for the lengths equal to each other. For example, if lengths are given as 2x + 20 and x + 21, the equation would be 2x + 20 = x + 21.

Front

What is the definition of Probability?

Back

Probability is the measure of the likelihood that an event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is a Sample in Statistics?

Back

A Sample is a subset of a population used to represent the entire group in statistical analysis.

Front

What is the difference between Mean, Median, and Mode?

Back

Mean: The average of a set of numbers. Median: The middle value when numbers are arranged in order. Mode: The number that appears most frequently.

Front

What is a Complementary Angle?

Back

Complementary Angles are two angles whose sum is 90 degrees.

Front

What is the formula for calculating the area of a triangle?

Back

Area = 1/2 * base * height.
