Regina has a bag of 6 orange marbles and 6 black marbles. She picks a marble at random and then puts it back in the bag. She does this 24 times. The results are shown in the table. Determine the percent error of pulling a black marble in Reginas experiment. Show your work and round your answer to the nearest hundredth.

16.67%

Step-by-step explanation:

The theoretical probability is:

P(black) = 6/12 = 0.5

The experimental probability is:

P(black) = 14/24 = 0.583

The percent error is:

e = (0.583 − 0.5) / 0.5 × 100%

e = 16.67%

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
