Answer:
67 - 5 = 62
67+5 = 72
Step-by-step explanation:
the real life scenario has been described under this paragraph. take note that I used a number which when added to another number gives 72, and when I subtract this number from the other number, I also get 62
let's assume that a teacher carries out a study in his class and found out that 67percent of his students support indoor sporting activities, if there is an error of 5%, find the minimum and also the maximum percentage of students who are in favor of indoors sporting activities.
|x - 67| = 5
such that
x = 67 +-5
x = 67+5 = 72
x = 67-5 = 62
x= 62, x = 72
