A thermometer with a percent error of 6.5% reads the room temperature as 68°F. what is the actual temperature in the room ?
Lynna [10]

<u>Answer:</u>

<em>Actual temperature for the given temperature with thermometer with error of 6.5% is 63.8 degrees.</em>

<u>Explanation:</u>

The percentage error in thermometer is 6.5%  this means that if the temperature is 100 degrees the thermometer shell show 106.5 degrees. now calculating the <em>actual temperature of the thermometer when the given temperature is 68°</em>

<em>Applying unitary method for solution 106.5</em>

Then 100 will be\frac {68}{106.5} \times 100

= 0.6384 \times 100

= <em>63.8 Degrees</em>

<em>On solving the value of this equation will give the actual temperature as 63.8 Degrees .</em>
