A rectangle has a perimeter of 36 cm and a length of 10 cm. What is the width?
Answer: 8 cm
Using P = 2(l + w): 36 = 2(10 + w), so 18 = 10 + w, giving w = 8 cm.
Which measure of central tendency is most affected by outliers?
Answer: Mean
The mean uses all data values in its calculation, so extreme outliers pull it significantly higher or lower.
In the OAE content framework, proportional reasoning is primarily associated with which grade band?
Answer: 6–8
Proportional reasoning is a cornerstone of the middle grades (6–8) mathematics curriculum in Ohio standards.
A teacher wants to assess conceptual understanding of fractions. Which task best measures this?
Answer: Explain why 1/2 > 1/3 using a number line
Explaining reasoning using a number line demonstrates conceptual understanding of fraction magnitude rather than procedural skill alone.
Which transformation preserves the size and shape of a figure?
Answer: Isometry (congruence transformation)
Isometries—translations, reflections, and rotations—preserve both size and shape, maintaining congruence.
Probability of an event A is 0.3. What is the probability of the complement of A?
Answer: 0.7
The complement rule states P(A') = 1 − P(A) = 1 − 0.3 = 0.7.
