an advertising company made 15 million in 2002 and 22 million in 2003. in a bar graph of this data, the bar for 2002 is 3 inches high. How high should the bar for 2003 be to represent the data proportionally?
15 million/3 = 22 million/x
15 million x = 66 million
x = 66/15
x = 4.4
4.4
To represent the data proportionally in a bar graph, we need to consider the ratio between the two values and scale the bar height accordingly.
First, let's calculate the ratio between the two values:
Ratio = Value in 2003 / Value in 2002
In this case, the value in 2003 is 22 million and the value in 2002 is 15 million.
Ratio = 22 million / 15 million
Simplifying the ratio, we get:
Ratio = 1.4667
Next, we need to scale the bar height for 2003 based on this ratio.
Since the bar height for 2002 is given as 3 inches, we can multiply it by the ratio to determine the proportional height for 2003:
Proportional height for 2003 = 3 inches * Ratio
Calculating the proportional height for 2003:
Proportional height for 2003 = 3 inches * 1.4667
Therefore, the bar for 2003 in the bar graph should be approximately 4.4 inches high in order to represent the data proportionally.
