Proportional Relationships in Tables QUIZ

How do you determine if a missing value in a proportional table is correct?

• By checking if the ratios remain constant.

• By calculating the average of the known values.

• By comparing it to the largest value in the table.

• By ensuring all values are whole numbers.

If Abigail works 12 hours and earns $36, what is her hourly wage?

• $2 per hour

• $3 per hour

• $4 per hour

• $5 per hour

What is the constant of proportionality?

• The constant ratio between two proportional quantities, often represented as k.

• A variable that changes with the input value.

• The maximum value in a set of data.

• The average of all values in a proportional relationship.

If a table shows values (1, 2), (2, 4), (3, 6), is this a proportional relationship?

• Yes, because the ratio is constant (2:1).

• No, because the values are not equal.

• Yes, but only for the first two values.

• No, because the relationship is not linear.

If a table shows the relationship between distance and time, how do you find the speed?

• Speed can be found by dividing distance by time.

• Speed can be found by multiplying distance by time.

• Speed can be found by adding distance and time.

• Speed can be found by subtracting time from distance.

What is the formula to calculate the constant of proportionality?

• C.o.P. = y/x, where y is the output and x is the input.

• C.o.P. = x/y, where y is the output and x is the input.

• C.o.P. = y + x, where y is the output and x is the input.

• C.o.P. = y - x, where y is the output and x is the input.

What does it mean if a table does not show a proportional relationship?

• It means that the ratios of the corresponding values are not constant.

• It means that the values are always equal.

• It means that the values increase at a constant rate.

• It means that the table contains only whole numbers.

If a car travels 90 miles in 2 hours, what is the constant of proportionality in miles per hour?

• 30 miles per hour

• 45 miles per hour

• 60 miles per hour

• 75 miles per hour

What happens to the constant of proportionality if both quantities are doubled?

• The constant of proportionality remains the same.

• The constant of proportionality doubles.

• The constant of proportionality becomes zero.

• The constant of proportionality is halved.

If a table shows the values (5, 15), (10, 30), (15, 45), what is the constant of proportionality?

• 1

• 2

• 3

• 4
