Respuesta :
The mean for Nancy is 2 tablespoon
Step-by-step explanation:
Average tablespoon to be added to 2 litres of water= 2 tablespoon
ceiling value (bigger of the two values)= one more than average tablespoon= (2+1) 3 tablespoon
Floor value (smaller of the two values)= one less than average tablespoon= (2-1) 1 tablespoon
Mean value of the tablespoon= (floor value+ceiling value)/2
Substituting the values of floor value and ceiling value
Thus the value is 2 tablespoon
Mean tablespoon allowed by Nancy in the two litres of seltzer water is 2 tablespoon.
