Answer:
<h3>9x²-3x+1</h3>
Step-by-step explanation:
The rate of the change of the car is is its speed.
Speed = distance/time
Given
Distance = 27x³-9x²+3x
Time = 3x hours
Speed = 27x³-9x²+3x/3x
factor out 3x from the numerator:
Speed = 3x(9x²-3x+1)/3x
Speed = 9x²-3x+1
Hence the rate of the car is 9x²-3x+1
Answer:
B. The experimental probability of a 1 is 25%.
Step-by-step explanation:
Since there are 4 sections of equal size, the theoretical probability of landing on any one of the them is equal. The probability of landing on any one of the sections is 25%. The experimental probability is based on the results of an actual experiment, meaning spinning the spinner, and recording the results.
A. The theoretical probability of a 1 is 25%. True as explained above.
B. The experimental probability of a 1 is 25%. False. There were three spins. One spin resulted in a 1. The experimental probability of spinning a 1 is 1/3 or 33 1/3 %.
C. If you spin the same spinner again and get different results, the experimental probabilities are different, but the theoretical probabilities have not changed. True. See explanation above. The theoretical probability is always 25% for any of the sections, 1, 2, 3, or 4. The experimental probability depends on the results of the actual spins that were performed.
D. The experimental probability of a 2 is 0%. True. The spinner was spun 3 times. There was no result of a 2, so the experimental probability of landing on a 2 is 0%.
Answer: The false statement is B. The experimental probability of a 1 is 25%.
Hello, The answer to this question is, A. $12.48
If I remember correctly judging from the 30 in the top left all you would have to is subtract 180 which is the angle of a straight line and subtract it from the 30 and it would be 150
