Example Questions

Example Question #101 : Data Analysis And Probability

What is the next number in the sequence?

\(\displaystyle 4, 8, 12, 16, 20,\) __________

Possible Answers:

\(\displaystyle 28\)

\(\displaystyle 22\)

\(\displaystyle 24\)

\(\displaystyle 36\)

\(\displaystyle 18\)

Correct answer:

\(\displaystyle 24\)

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is adding by fours! So, to find the next number, we need to add four more to the last number in the given sequence.

\(\displaystyle 20 + 4 = \mathbf{24}\)

Example Question #102 : Data Analysis And Probability

What is the next number in the sequence?

\(\displaystyle 2, 4, 8, 16, 32,\) __________

Possible Answers:

\(\displaystyle 12\)

\(\displaystyle 24\)

\(\displaystyle 64\)

\(\displaystyle 48\)

\(\displaystyle 36\)

Correct answer:

\(\displaystyle 64\)

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is multiplying by twos! So, to find the next number, we need to mulitply the last number by two in the given sequence.

\(\displaystyle 32\times 2=64\)

Example Question #103 : Data Analysis And Probability

What is the missing number in the sequence?

\(\displaystyle 5, 15,\) __________ \(\displaystyle 135\)

Possible Answers:

\(\displaystyle 45\)

\(\displaystyle 65\)

\(\displaystyle 60\)

\(\displaystyle 55\)

\(\displaystyle 50\)

Correct answer:

\(\displaystyle 45\)

Explanation:

To find the next number in the sequence, we need to find the pattern. In this problem, the pattern is multiplying by threes.

\(\displaystyle $15\times 3$ = 45\)

Example Question #104 : Data Analysis And Probability

Of the options provided, which would make the most sense to use if we were going to measure a phone? 

Possible Answers:

Ruler

Meter stick

Measuring tape

Yardstick

Correct answer:

Ruler

Explanation:

You would use a ruler to measure a phone because a phone is most likely smaller than \(\displaystyle 12\) inches, which is the size of a ruler. The other tools are much larger. 

Example Question #2 : Measurement & Data

Of the options provided, which would make the most sense to use if we were going to measure a room?

Possible Answers:

 Meter stick 

Ruler

Measuring tape

Yardstick

Correct answer:

Measuring tape

Explanation:

A room is most likely larger than what a yardstick, meter stick, and ruler could measure. A ruler can only measure up to \(\displaystyle 12\) inches, a yardstick can only measure up to \(\displaystyle 3\) feet (or \(\displaystyle 36\) inches), and a meter stick is about the same size as a yardstick. Measuring tape can measure over \(\displaystyle 25\) feet. 

Example Question #105 : Data Analysis And Probability

What is the missing value in the following list?

\(\displaystyle 2,5,8,x,14\)

Possible Answers:

\(\displaystyle 10\)

\(\displaystyle 12\)

\(\displaystyle 13\)

\(\displaystyle 8\)

\(\displaystyle 11\)

Correct answer:

\(\displaystyle 11\)

Explanation:

First you have to find the pattern between each value in the list.  

You find that each number is \(\displaystyle 3\) higher than the last 

\(\displaystyle (2+3=5, 5+3=8)\).  

Then you add the difference to the number before \(\displaystyle x\) and that gives you \(\displaystyle 11\) 

\(\displaystyle (8+3=11)\).

Example Question #1 : Measurement & Data

Which would make the most sense to use if we were going to measure a candle?

Possible Answers:

Yardstick

Meter stick

Ruler

Measuring tape

Correct answer:

Ruler

Explanation:

You would use a ruler to measure a shoe because a candle is most likely smaller than 12 inches, which is the size of a ruler. All of the other tools will be much larger. 

Example Question #1 : Select The Correct Tool To Measure Objects: Ccss.Math.Content.2.Md.A.1

Which would make the most sense to use if we were going to measure a taco?

Possible Answers:

Meter stick

Ruler

Yardstick

Measuring tape

Correct answer:

Ruler

Explanation:

You would use a ruler to measure a taco because a taco is most likely smaller than 12 inches, which is the size of a ruler. All of the other tools will be much larger. 

Example Question #106 : Data Analysis And Probability

\(\displaystyle Place\;the\;following\;numbers\;in\;order\;from\;least\;to\;greatest: -3,\frac{1}{2},0,-50\)

Possible Answers:

\(\displaystyle 0,\frac{1}{2},-50,-3\)

\(\displaystyle -50,-3,0,\frac{1}{2}\)

\(\displaystyle -50,-3,\frac{1}{2},0\)

\(\displaystyle \frac{1}{2},0,-3,-50\)

Correct answer:

\(\displaystyle -50,-3,0,\frac{1}{2}\)

Explanation:

\(\displaystyle -50< -3< 0< \frac{1}{2}\)

\(\displaystyle Negative\;numbers\;are\;smaller\;than\;0.\)

\(\displaystyle Positive\;number\;are\;greater\;than\;0.\)

 

Example Question #107 : Data Analysis And Probability

Which of the choices below lists ONLY examples of triangles?

Possible Answers:

equilateral, parallelogram, trapezoid

rhombus, kite, trapezoid

 isosceles, scalene, equilateral

pentagon, isosceles, kite

Correct answer:

 isosceles, scalene, equilateral

Explanation:

isosceles: triangle with two equal sides and two equal angles

scalene: triangle with no equal sides and no equal angles

equilateral: triangle with three equal sides and three equal angles
