Answer:

21%

Step-by-step explanation:

to find percent error you subtract the theoretical (actual) from the experimental, then divide by the theoretical; what you get is a decimal so if you multiply it by 100 you will get the percent

theoretical = 2.0 grams

experimental = 1.65 grams

(1.65 - 2.0) / 1.65 = -0.35/1.65 = -0.21

0.21 x 100 = 21 %

the scale has a 21% probability of being inaccurate

Answer

f(-4) = 125, g(6) = -13

Step-by-step explanation:

all of those symbols might look really scary, but really all the problem is asking you to do is substitute -4 into the x in f(x) and 6 into the x in g(x) -- basically, f(-4) = $-2((-4)^{3}) - 3$ = 125, and g(6) = $-2(6) - 1$ = -13. there are your answers!
