PEI Math 521A Practice Questions - Secondary Mathematics Assessment - Math 521A - Prince Edward Island Exam - PEI Math 521A Practice Questions - Secondary Mathematics Assessment - Math 521A

Question 1

Consider the sequence of pattern results: $3 \times 5 = 15$, $35 \times 5 = 175$, $335 \times 5 = 1675$. Based on inductive reasoning, what is the expected value of $3335 \times 5$?

16675 16685 16775 16755

Correct Answer:

16675

Question 2

A student conjectures that 'for all real numbers $x$, $x^2 > x$'. Which of the following numbers serves as a valid counterexample to disprove this conjecture?

$$x = -2$ $$x = 0.5$ $$x = 2$ $$x = 3$

Correct Answer:

$$x = 0.5$

Question 3

Which of the following represents a correct deductive proof showing that the sum of two odd integers is always an even integer?

Let the numbers be $2n+1$ and $2m+1$. Their sum is $(2n+1)+(2m+1) = 2n+2m+2 = 2(n+m+1)$, which is divisible by 2. Test $3+5=8$ and $7+9=16$. Since 8 and 16 are even, all sums of two odd numbers must be even. Let the numbers be $n$ and $n+2$. Their sum is $2n+2 = 2(n+1)$, which is even. Assume the sum of two odd numbers is odd, then find that $3+3=6$, which contradicts the assumption.

Correct Answer:

Let the numbers be $2n+1$ and $2m+1$. Their sum is $(2n+1)+(2m+1) = 2n+2m+2 = 2(n+m+1)$, which is divisible by 2.

Question 4

Consider the argument: 'All prime numbers greater than 2 are odd. The number 17 is odd. Therefore, 17 is a prime number.' Is this argument valid or invalid, and why?

Valid, because the conclusion that 17 is prime is mathematically true. Invalid, because it commits the fallacy of affirming the consequent. Valid, because both premises are true statement facts. Invalid, because 17 is actually an even number.

Correct Answer:

Invalid, because it commits the fallacy of affirming the consequent.

Question 5

If the pattern $1 = 1^2$, $1 + 3 = 2^2$, $1 + 3 + 5 = 3^2$, and $1 + 3 + 5 + 7 = 4^2$ continues, what is the sum of the first 12 consecutive odd positive integers?

144 124 132 156

Correct Answer:

144
