Answer the following.
nexus9112 [7]

Step-by-step explanation:

1075 students were asked how close they live to the college. The table shows the results below with some values missing. Enter the correct values in the boxes remembering to use the % symbol where necessary.

<u>20 to 25: </u>given 20%

20% of 1,075 = 215

<u>15 to 19: </u>given 12%

12% of 1,075 = 129

<u>10 to 14: </u>given 516 students

(516/1,075)*100 = 48%

<u>5 to 9: </u>given 162 students

(162/1,075)*100 = 15.07%

<u>< 5: </u>given 53 students

(53/1,075)*100 = 4.93%
