Step-by-step explanation:
The student found the cosine of angle A not the sine. Sine is Opposite/Hypotenuse. This student found Adjacent/Hypotenuse. The correct answer is Sin A= 12/13.
Step-by-step explanation:
-10x + 4 = -7x - 14 - 7x - 14
-10x + 4 = -14x - 28
4x = -32
x = -8.
Hint: First, divide 15/100 by -7 1/2 to find the speed, then use -70 to divide the speed to get an answer!!
Answer: Experimental probability is the probability based off of real results. It is always equivalent to the number of a certain color spun (in this case, black) divided by the number of trials, 20. The experimental probability is 1/20. The theoretical probability is more like the technical probability of landing on a color. In this case, theoretical probability would be 2/10, or simplified, 1/5. If the spinner is fair, then as the number of spins increases, the probabilities will become closer.
