The medicinal thermometer commonly used in homes can be read to â±0.1â°f, whereas those in the doctor's office may be accurate to â±0.1â°c. percent error is often expressed as the absolute value of the difference between the true value and the experimental value, divided by the true value: percent error= [|true value - experimental value|/true value]x 100%. the vertical lines indicate absolute value. in degrees celsius, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.9â°c.

the percent error expected from each of theses person's body:

in homes:

% E = 0.14267 %

in doctor's office:

% E = 0.257 %

Explanation:

thermometer used in homes:

⇒ T = 102.02 ° F  +/- 0.1 ° F = 102.12 ° F ∧  101,92 ° F

⇒ T = 102.12 ° F  = 38.9555 ° C

⇒ % E = ( | 38.9 - 38.9555 | ) / 38.9 ) * 100 = 0.14267 %

in the doctor's oficce:

⇒ T = 38.9 ° C  +/- 0.1 ° C = 39 ° C ∧ 38.8 ° C

⇒ % E = (( | 39 - 38.9 | ) / 38.9 ) * 100 = 0.257 %

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
