What is a scale factor?1 / 9

A scale factor is the number you multiply every length of a figure by to make a similar, larger or smaller copy. If the scale factor is 2, every side becomes twice as long.

State the formula for sin(A + B).1 / 8

Note this is NOT sin A + sin B — a common mistake. The sine of a sum mixes both angles' sines and cosines.

What does 'rate of change' mean?1 / 10

Rate of change tells you how much one quantity changes compared to another — usually how much y changes for every step in x. On a graph, it's how steeply the line climbs or falls.

When graphing an inequality on a number line, when do you use an open circle versus a closed (filled) circle?1 / 9

An open circle means the boundary value is NOT part of the solution — used for < and >. A closed (filled) circle means the boundary value IS included — used for ≤ and ≥.

What is a point estimate vs an interval estimate?1 / 11

A point estimate is a single statistic (e.g., x̄) used to estimate a population parameter (μ). An interval estimate (confidence interval) provides a range [L, U] that captures the true parameter with a stated confidence level (e.g., 95%).
