Front

What is the slope of a line of best fit in a scatterplot?

Back

The slope of a line of best fit represents the predicted change in the dependent variable (y) for a one-unit increase in the independent variable (x).

Front

How do you interpret the slope in the context of a scatterplot showing the relationship between two variables?

Back

The slope indicates the predicted increase or decrease in the dependent variable for each unit increase in the independent variable.

Front

What is the formula for calculating the total cost including tax?

Back

Total Cost = (Room Rate * Number of Nights * (1 + Tax Rate)) + Additional Fees.

Front

How do you set up an inequality to represent a situation with minimum requirements?

Back

Use the form: Coefficient1 * Variable1 + Coefficient2 * Variable2 ≥ Minimum Requirement.

Front

What is the probability of selecting a specific item from a group?

Back

Probability = (Number of Favorable Outcomes) / (Total Number of Outcomes).

Front

How do you calculate the total charge for staying at a hotel with a nightly rate and tax?

Back

Total Charge = (Nightly Rate * Number of Nights * (1 + Tax Rate)) + Additional Fees.

Front

What does it mean if a scatterplot shows a positive correlation?

Back

A positive correlation means that as one variable increases, the other variable also tends to increase.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept represents the value of the dependent variable when the independent variable is zero.

Front

How do you determine the number of items needed to meet a specific condition?

Back

Set up an equation or inequality based on the condition and solve for the variable.

Front

What is the relationship between the length of a bone and height in a scatterplot?

Back

The relationship can be analyzed using the line of best fit to predict height based on bone length.
