Front

What method will result in the least biased decision for a field trip survey among 7th graders?

Back

Randomly choose some 7th grade students to select a location.

Front

Write the equation for a relationship where y is directly proportional to x with a constant of proportionality of 5.

Front

What is the equation in y=kx form where k is the constant of proportionality for the relationship between miles traveled (x) and gallons of gas used (y) if y is proportional to x with k = 1/35?

Back

Front

Select the expression that represents the operations shown on the number line: 8n - 2n - 14n.

Back

This expression simplifies to 8n - 2n - 14n.

Front

Define the term 'constant of proportionality'.

Back

The constant of proportionality is the constant factor that relates two proportional quantities, often represented as k in the equation y = kx.

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio to each other.

Front

How do you find the constant of proportionality from a table of values?

Back

Divide the value of y by the corresponding value of x for any pair of values.

Front

What is the formula for calculating the total cost (t) based on the number of items (n) and the cost per item?

Back

Front

What is the significance of a random sample in surveys?

Back

A random sample helps ensure that every member of a population has an equal chance of being selected, reducing bias.
