State the precision and uncertainty of each measurement, if possible. a) A tool and die maker measure the width of a block to be \( 2.5002^{\prime \prime} \) b) A chef cooks potatoes for 58 minutes. c) A dairy farmer measure 8.2 kg of feed.

Write the maximum and minimum values represented by each of the following dimensions a) \( 1.375^{\circ} \mathrm{C} \pm 0.025^{\circ} \mathrm{C} \) b) \( 8 " \pm \frac{1}{8} \) c) \( 23_{-2}^{+0} \mathrm{~mm} \) d) \( 245_{-0}^{+5} \mathrm{~m} \)

Express each measurement in the following form: measurement \( \pm \) uncertainty a) Barry measures a 2 m piece of particle board using a tape measure that is marked in 1 mm increments. b) A poultry farmer prepares 15 mL of antibiotics in a syringe marked in 1 mL increments c) The speedometer on a car reads \( 35 \mathrm{~km} / \mathrm{h} \) with speed marked every \( 5 \mathrm{~km} / \mathrm{h} \)

Jim works in an automotive repair shop. A manufacturer that supplies spark plugs says the spark plug gap should be \( 0.048^{\prime \prime}-0.052^{\prime \prime} \). Determine the: a) tolerance b) nominal value

State the measurement with a minimum of 47.5 and a maximum of 52.5 cm in the form: Nominal value \( \pm \frac{1}{2} \) (tolerance)
