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%.
Answer:
If its -2x^2+17 the answer would be -183.
Step-by-step explanation:
-2(100)+17
-200+17
= -183
Answer: A vertex contains an infinite number of points, and a point does not have width or depth.
Step-by-step explanation:
Answer:
39°
sum of triangle's interior angles: 180°
180°-90°-51°=39°
Area of a rectangle is L * W
L = x
W = 5
5x = 20 (Divide by 5 on both sides)
x = 4
L=4
W= 5
The length is 4cm
Hope this helps :)
