Since we do not know the exact number of Marbles of each color we will use the data of the experiment to calculate the probability. The probability calculated based on the results of an experiment is termed as experimental probability.
So, we have the calculate the experimental probability that a randomly drawn marble is blue.
Total number of trials = 1200
Number of times blue showed up = 845
Therefore, the experimental probability of randomly drawing a blue marble = 845/1200 = 169/240 = 0.704 (Rounding to nearest thousandth)
Therefore, the probability that a random blue marble is drawn is 0.704 or 169/240
Answer:
x = 5 or x = - 1/2
Step-by-step explanation:
2x² - 9x-5 = 0
(x -5) (2x + 1) = 0
x = 5 or x = - 1/2
Proof (reasons are given in brackets):
Consider , :
(given)
(vertically opposite angles are equal)
(given)
(SAS)
Hope this helps :)
F(5) = -1 would be the correct answer.
