There is no image of the table given.

Given:
approximate number = 75 
exact number = 95

error = |approximate number - exact number| ÷ exact number
error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%

Answer:

Given:

approximate number = 75

exact number = 95

error = |approximate number - exact number| ÷ exact number

error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%
