Calculate the number of minutes in one week.

One week = 7 days

1 day = 24 hours

1 hour = 60 minutes

1 week * 7 (days per week) * 24 (hours per day) * 60 (minutes per hour) = 10,080 minutes

Convert 180 seconds into minutes.

1 minute = 60 seconds

180 seconds / 60 (seconds per minute) = 3 minutes

Flashcard Content Overview

These flashcards look at three common concepts you will likely come across in daily life. The first is standard units of measurement, such as pounds and liters, and how to convert between different units that are used to measure the same thing. Second, these flashcards will look at sequences in math and how to generate formulas to determine missing values in a specific sequence. Finally, they will review the basics of working with data sets.

Sequence

Things in a group, like numbers, that follow a specific pattern

Can be infinite or finite

Arithmetic Sequence

A sequence in which the numbers follow a pattern of repeated addition

Geometric Sequence

A sequence in which the numbers follow a pattern of repeated multiplication

Determine the values missing in the following sequence: 2, 5, 8, _____, 14, _____, 20.

Formula = 3(n-1) + 2

When n = 4, 3(n- 1) + 2 = 11

When n = 6, 3(n- 1) + 2 = 17

Determine the values missing in the following sequence: 2, 8, _____, 128, _____.

Formula = 2 * 4^(n - 1)

When n = 3, 2 * 4^(n- 1) = 32

When n = 5, 2 * 4^(n- 1) = 512

Variance

Describes how spread out a set of numbers is

To calculate: find the mean, subtract each value from the mean and square the result, add the squared values and divide by the number of values

Interquartile Range

The difference between the upper and lower quartiles of a data set

Find the second worst test score from the following list of students: Student A-98%; Student B-67%; Student C-97%; Student D-77%; Student E-87%; Student F-55%.

Ranked in order from worst to best: F, B, D, E, C, A

Second worst: Student B

Predictive Statistics

A type of statistics that attempts to forecast future events or conditions based on current data

Inferential Statistics

A type of statistics that looks for patterns and relationships between variables in data sets

Descriptive Statistics

A type of statistics that uses to measures of central tendency (like average) and visual (like charts and graphs) to represent data

Quantitative Data

Numerical data that is collected and can be analyzed using statistics

Qualitative Data

Opinions and insights collected through exploratory research such as interviews and observations
