x = 13.165 y = 7.686 z = 11.545 the number a is obtained by first rounding the values of x , y , and z to the hundredths place and then adding the resulting values . the number b is obtained by first adding the values of x , y , and z and then rounding the sum to the hundredths place . what is the value of a – b ?
rounding off the values : x = 13.17 y = 7.69 z = 11.55 a = 13.17 + 7.69 + 11.55 = 32.41 x + y + z = 13.165 + 7.686 + 11.545 = 32.206 b = 32.21 a - b = 0.2 option e
divide(subtract(add(floor(multiply(add(add(13.165, 7.686), 11.545), const_100)), const_1), add(floor(multiply(11.545, const_100)), add(floor(multiply(13.165, const_100)), floor(multiply(7.686, const_100))))), const_10)
