Question

Lower bound 82.8 measured to the nearest tenth of a cm

Answer 1

Step-by-step explanation:

Given Lower bound 82.8 measured to the nearest tenth of a cm

• We know that the Lower bound is the smallest value that is rounded to the estimated value.
• To calculate upper and lower bounds we can divide the degree by 2 (half) and add to the rounded value for upper bound but subtract for the lower bound.
• Now degree is nearest 10 th place or 10 cm
• So 10 / 2 = 5 cm
• Lower bound = 82.8 – 5 = 82.3 cm
• Upper bound = 82.8 + 5 = 83.3 cm
