Complete the frequency table: Method of Travel to School Walk/Bike Bus Car Row totals Under age 15 60 Age 15 and above 65 195 Column totals 152 110 98 360 How many students age 15 and above take a car to school? 18 38 50 87.

Answer 1

By analyzing the frequency table and subtracting known values from row and column totals, it is found that 38 students age 15 and above take a car to school.

Step-by-step explanation:

To determine how many students age 15 and above take a car to school, one can look at the provided frequency table. The row totals must reflect the sum of students in each age category, and the column totals must reflect the sum of students using each method of travel. Since there are 360 students in total and 152 take Walk/Bike, 110 take the Bus, the remaining number of students who travel by Car can be calculated as 360 - (152 + 110) = 98.

Furthermore, if 60 students under age 15 take Walk/Bike, and the column total is 152, then the remaining 92 students (152 - 60) must be age 15 and above. With the total for age 15 and above being 195, and knowing that 92 take Walk/Bike and 65 take the Bus, we can determine the frequency of those who take a Car by subtraction: 195 - (92 + 65) = 38.

Therefore, 38 students aged 15 and above take a car to school.

Answer 2

The number of students age 15 and above take a car to school is 80 students.

How many students age 15 and above take a car to school?

Number of children age 15 and above who takes bus to school = column totals of bus - under age 15(bus)

= 110 - 60

= 50

Number of children age 15 and above who takes car to school = Row totals of age 15 and above - (walk/bike + bus) 15 and above

= 195 - (65 + 50)

= 195 - 115

= 80 students

Therefore, 80 students age 15 and above take a car to school.
