What is the equation to model landscaping costs for Company B if c represents the cost and s represents the yard size?

Back

c = (Company B's cost equation, which is not provided in the image)

Front

What is the cost for Company B to landscape a yard of 1,500 ft²?

Back

$32.50

Front

What does it mean when we say that higher temperatures are correlated to higher car sales?

Back

It means that as temperatures increase, car sales tend to increase, but one does not necessarily cause the other.

Front

Define 'correlation' in the context of data analysis.

Back

Correlation refers to a statistical relationship between two variables, indicating how one may change in relation to the other.

Front

What is the vertex form of a quadratic equation?

Back

Front

What does it mean for a function to be 'moved left' on a graph?

Back

It means that every point on the graph is shifted horizontally to the left by a certain number of units.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the highest or lowest point of the parabola, depending on the direction it opens.

Front

How do you determine the cost of landscaping based on yard size?

Back

You can use a cost equation that relates the cost (c) to the yard size (s), such as c = ms + b, where m is the rate per square foot and b is a fixed cost.
