Front

What is a cold front?

Back

A cold front is a boundary between a mass of cold air and a mass of warm air, where the cold air pushes the warm air upward, often leading to a drop in temperature.

Front

How do you calculate the rate of change in temperature?

Back

To calculate the rate of change in temperature, divide the total change in temperature by the time interval over which the change occurred.

Front

If a cold front causes a temperature drop of 10 degrees over 5 hours, what is the rate of temperature change per hour?

Back

The rate of temperature change is 2 degrees per hour (10 degrees / 5 hours).

Front

What is the formula to find the total number of baskets woven over time?

Back

The formula is: Total Baskets = (Baskets per hour) * (Total hours).

Front

If Olivia weaves 2 baskets every 3 hours, how many baskets can she weave in 18 hours?

Back

Olivia can weave 12 baskets in 18 hours.

Front

What is a deposit in a purchase?

Back

A deposit is an initial payment made to secure a purchase, which is typically deducted from the total cost.

Front

How do you represent total cost with an equation?

Back

The total cost can be represented by the equation: Total Cost = Deposit + (Monthly Payment * Number of Months).

Front

What does the slope of a line represent in a linear equation?

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data, showing the relationship between them.

Front

What does a positive, linear trend in a scatterplot indicate?

Back

A positive, linear trend indicates that as one variable increases, the other variable also increases in a consistent manner.
