Question #f903e

Answer 1

a) -4.11%
b) 2.74%
c) 0%
d) -1.36%

Explanation:

"Percent error" is the difference between the "actual" value and the measured value.
`%"error" = ("measured" - "actual")/"actual" xx 100`

7.0: `%"error" = (7.0 - 7.3)/7.3 xx 100 = -4.11%`

7.5: `%"error" = (7.5 - 7.3)/7.3 xx 100 = 2.74%`

7.3: `%"error" = (7.3 - 7.3)/7.3 xx 100 = 0%`

7.2: `%"error" = (7.2 - 7.3)/7.3 xx 100 = -1.36%`
