Answer:
Step-by-step explanation:
The following table shows the relationship between students who enroll in advanced Algebra and Chemistry in a particular high school. From a sample of 40 students it is found that 17 are enrolled in Algebra, 12 are enrolled in Chemistry, and six are enrolled in both.
Algebra Not in Algebra Total
Chemistry 6 12
Not in Chemistry
Total 17 40
Complete the rest of the two-way frequency table above.
Part A: How many students are enrolled in either Algebra or Chemistry?
Part B: If there are 2,000 students in this school, how many (rounded to the nearest whole student) are expected to be enrolled in just Chemistry this year?
I already filled out the graph but I think I might have somehow did it wrong.
