<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a measure of how similar two datasets are acting.

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.

One data increases and other data starts to decrease in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

The correlation shown by the graph is negative.

From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).

Mario and Luigi have friends. They want to purchase some extra controllers. Each controller costs $29.99.
jonny [76]
An algebraic expression is a phrase in mathematics that consists of numbers such as 1,2,3 and the like, variables which are represented with letters and operations like addition, multiplication, subtraction and division. It is usually used to represent a certain situation which would relate the variables involved. To write the algebraic expression for the problem statement above, we do as follows:

Let x = number of consoles to be bought
      y = number of games to be bought
      z = number of controllers to bebought
     C = total cost of all

The total cost would be equal to the sum of the price multiplied by the number of consoles, games and controllers bought. We write the algebraic expression as follows,

C = 299x + 59.99y + 29.99z
