The answer I got was A f(-4)=x
Answer:
A. 18°
Step-by-step explanation:
Using the cofunction identity
sin x = cos(90 - x)
Hence
sin72° = cos(90 - 72)° = cos18° ⇒ ∠Y = 18°
Answer:
The answer to your question is 49
Step-by-step explanation
4+3=7 So she uses 7 Flowers per vase and she wants to fill 7 vases so just do 7*7 and the answer is 49!
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%.
