1. QuestionMultiple choice

What is the vertex of y = (x − 2)^2 − 5?

Please select an answer first.

Correct answer: A

The correct answer is (2, −5).

  1. Identify the mathematical model: Determine whether the task uses an equation, function, geometric relationship, probability model, statistic, or constraint.
  2. Show the calculation: Vertex form y = (x − h)^2 + k has vertex (h, k), so the vertex is (2, −5).
  3. Check the result: Substitute the answer, inspect the units, estimate the value, or compare it with the graph or context.

Vertex form y = (x − h)^2 + k has vertex (h, k), so the vertex is (2, −5).

2. QuestionMultiple choice

A right triangle has an angle of 30 degrees and hypotenuse 10 units. What is the side opposite the angle?

Please select an answer first.

Correct answer: B

The correct answer is 5 units.

  1. Identify the mathematical model: Determine whether the task uses an equation, function, geometric relationship, probability model, statistic, or constraint.
  2. Show the calculation: Use sin(30) = opposite ÷ 10 = 1/2, so the opposite side is 5 units.
  3. Check the result: Substitute the answer, inspect the units, estimate the value, or compare it with the graph or context.

Use sin(30) = opposite ÷ 10 = 1/2, so the opposite side is 5 units.

3. QuestionMultiple choice

If the probability of event A is 0.7, what is the probability that A does not occur?

Please select an answer first.

Correct answer: C

The correct answer is 0.3.

  1. Identify the mathematical model: Determine whether the task uses an equation, function, geometric relationship, probability model, statistic, or constraint.
  2. Show the calculation: The complement is 1 − 0.7 = 0.3.
  3. Check the result: Substitute the answer, inspect the units, estimate the value, or compare it with the graph or context.

The complement is 1 − 0.7 = 0.3.

4. QuestionMultiple choice

Two data sets have the same mean, but Set A has a larger standard deviation than Set B. What does this mean?

Please select an answer first.

Correct answer: D

The correct answer is Set A values are more spread out..

  1. Identify the mathematical model: Determine whether the task uses an equation, function, geometric relationship, probability model, statistic, or constraint.
  2. Show the calculation: A larger standard deviation indicates greater spread around the mean.
  3. Check the result: Substitute the answer, inspect the units, estimate the value, or compare it with the graph or context.

A larger standard deviation indicates greater spread around the mean.

5. QuestionMultiple choice

A rectangle has perimeter 40 units. If its length is x, which expression represents its width?

Please select an answer first.

Correct answer: A

The correct answer is 20 − x.

  1. Identify the mathematical model: Determine whether the task uses an equation, function, geometric relationship, probability model, statistic, or constraint.
  2. Show the calculation: Perimeter 2x + 2w = 40 gives x + w = 20, so w = 20 − x.
  3. Check the result: Substitute the answer, inspect the units, estimate the value, or compare it with the graph or context.

Perimeter 2x + 2w = 40 gives x + w = 20, so w = 20 − x.

6. QuestionMultiple choice

Which equation represents the inverse of f(x) = 3x − 6?

Please select an answer first.

Correct answer: B

The correct answer is f inverse of x = (x + 6)/3.

  1. Identify the mathematical model: Determine whether the task uses an equation, function, geometric relationship, probability model, statistic, or constraint.
  2. Show the calculation: Switch x and y and solve: x = 3y − 6 gives y = (x + 6)/3.
  3. Check the result: Substitute the answer, inspect the units, estimate the value, or compare it with the graph or context.

Switch x and y and solve: x = 3y − 6 gives y = (x + 6)/3.

7. QuestionMultiple choice
