The departments that account for one-fourth of the annual budget are sales, engineering and research departments
The pie chart that completes the question is added as an attachment.
From the attached image, we can see that each of the sales, engineering and research departments take 1/4 of the pie chart
Hence, the departments that account for one-fourth of the annual budget are sales, engineering and research departments
In (a), we have:
Engineering = 1/4 or 25%
From the graph
Support = 1/8 or 12.5%
So, the combined percentage is:
Combined = 25% + 12.5%
Evaluate
Combined = 37.5%
Approximate
Combined = 40%
In (a), we have:
Engineering = 1/4 or 25%
From the graph
Support = 1/8 or 15%
So, the combined percentage is:
Combined = 25% + 15%
Evaluate
Combined = 40%
From the graph;
Media = 1/3 of support.
So, we have:
Media = 1/3 of 15%
Evaluate
Media = 5%
Hence, the annual budget of media is 5%
