The radius of a circular disk is given as 21 cm with a maximum error in measurement of 0.2 cm.

ella [17]

Answer:

a) $\Delta A \approx 26.389\,cm^{2}$ , b) $r_{A} \approx 0.019$ , c) $\delta = 1.9\,\%$

Step-by-step explanation:

a) The area of the circular disk is modelled after this expression:

$A = \pi \cdot r^{2}$

The total differential is given by the following formula:

$\Delta A = 2\pi r \cdot \Delta r$

The maximum absolute error in the calculated area of the disk is:

$\Delta A = 2\pi \cdot (21\,cm)\cdot (0.2\,cm)$

$\Delta A \approx 26.389\,cm^{2}$

b) The relative error is given by:

$r_{A} = \frac{\Delta A}{A}$

$r_{A} = \frac{26.389\,cm^{2}}{\pi \cdot (21\,cm)^{2}}$

$r_{A} \approx 0.019$

c) The percentage error is:

$\delta = r_{A}\times 100\,\%$

$\delta = 0.019 \times 100\,\%$

$\delta = 1.9\,\%$

A nail manufacturer throws out nails with lengths that are not within 0.05 inch of the mean of the batch. The lengths (in inches

Natasha_Volkova [10]

Answer:

0.42 & 0.55

Step-by-step explanation:

Mean length = 0.42 + 0.53+ 0.55 + 0.48 + 0.51/5

= 0.498

0.42 - 0.498 = - 0.078‬

0.53 - 0.498 = 0.032‬

0.55 - 0.498 = 0.052‬

0.48 - 0.498 = - 0.018‬

0.51 - 0.498 = 0.012‬

The nails to be thrown out are:

0.42 & 0.55 because their deviations from the mean are not within 0.05 inch
