Answer: -7.408%
Explanation: The formula for percent error is:
(experimental - theoretical) / theoretical * 100. The experimental value is 50, or your guess. The theoretical value is 54, or the actual value. The theoretical value is the value it should be.
(50-54)/54 = -.074 * 100 = -7.408%
Answer:
0.8<x<1.1
Step-by-step explanation:
Take 0.9<2x-0.7<1.5 add everything by 0.7 to get 1.6<2x<2.2 then divide everything by 2 to get 0.8<x<1.1
That’s ur answer, your welcome
