Answer 1

@toxicsugar22 do you know?

Answer 2

@aaronq can you help?

Answer 3

You just have to use the formula written there at the bottom

Answer 4

i understand that, but which is the T.V and the E.V??? that's what i don't understand @aaronq

Answer 5

true value and experimental value. Did they not give you these?

Answer 6

what's in the picture is what we got

Answer 7

do you want the full question?

Answer 8

really? maybe they want you to assume that the body temp is 37 Celsius

Answer 9

but yeah, post the question

Answer 10

it said body temp was 38.9 C

Answer 11

was that supposed to be the measured temperature?

Answer 12

The medicinal thermometer commonly used in the homes can be read (+or-) 0.1F, whereas those in the doctor's office may be accurate to (+or-) 0.1C, express the percent error expected from each of these thermometers in measuring a person's body temperature of 38.9C.

Answer 13

ohh okay. So the true value is 38.9 C and the largest possible error is \(\pm0.1~^oC\)

So \(\sf percent~error =\dfrac{|true-experimental|}{true}*100\%\)

note that the absolute value bars and how it wont matter if you add or subtract 0.1 C from the value.

For celsius it's: \(\sf percent~error =\dfrac{|38.9^oC-39~^oC|}{38.9^oC}*100\%\)

Answer 14

Do the same for fahrenheit

Answer 15

what would the exp. be for F? 102.02 is true. so would exp. be 102.01?

Answer 16

102.02 F +0.1 F = 102.12 F

Answer 17

or 101.92

Answer 18

i'm getting .0980% (sorry it took so long, i got a phone call) @aaronq

Answer 19

yep, that seems good, i would round to 0.1 % though

Answer 20

Ok thank you!

Answer 21

no problem!
