Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.197 Model with Mathematics and Evaluate Results skill assessments:

Problem 1Difficulty: Mastery

What is the best evaluation of using the old model after the change?

AIt is automatically valid because it fit well before.

BIt will become perfect because more time has passed.

CThe relationship may have changed, so the model may no longer be valid without updating with new data.

DPolicy changes only affect the y-intercept, never the slope.

Solution & Explanation:A structural change in the real-world process can change the relationship between variables. A model built on pre-change data should be rechecked or refit with post-change data before drawing conclusions.

Problem 2Difficulty: Mastery

About how many time units t until p(t) reaches 50? Round to the nearest tenth.

Solution & Explanation:Set 50 = 100 ÷ (1 + 9(0.8)ᵗ). Then 1 + 9(0.8)ᵗ = 2, so 9(0.8)ᵗ = 1, so (0.8)ᵗ = 1/9. Take logs: t = ln(1/9) ÷ ln(0.8) ≈ 9.8.

Problem 3Difficulty: Mastery

Which statement correctly describes the implied model for y?

Ay is exponential in x: y = 10^(1.2) · 10^(0.30x)

By is linear in x: y = 0.30x + 1.2

Cy is quadratic in x

Dy must be negative for large x

Solution & Explanation:Undo the log₁₀ by raising 10 to both sides: y = 10^(0.30x + 1.2) = 10^(1.2)·10^(0.30x). That is an exponential model in x.
