A regular octagon can be concave.

True or False? Please explain.

Thanks!

Answers

Answer 1
Answer:

a regular polygon has all equal angles, interior and exterior, as well as all equal sides.

Check the picture below.

the one on the left is a regular octagon, as well as a convex one.

the one on the right is also an octagon, but is concave, the  issue is that, though all sides remain equal, the angles do not, and so is not a regular octagon.

On each trial of an experiment, a subject is presented with a constant soft noise, which is interrupted at some unpredictable time by a noticeably louder sound. The time it takes for the subject to react to this louder sound is recorded. The following list contains the reaction times (in milliseconds) for the trials of this experiment: 296, 311, 202, 217, 231, 171, 241, 164, 257, 269, 175, 273, 285, 226, 261 Find 25th and 80th percentiles for these reaction times.

Answers

Answer:

25th percentile = 202

80th percentile = 285

Step-by-step explanation:

Rearranging the values in increasing order

164

171

175

202

217

226

231

241

257

261

269

273

285

296

311

N = total number of variables = 15.

25th percentile = [(N + 1)/4]th variable = (15 + 1)/4 = 4th variable.

So, the 25th percentile = 4th variable = 202.

80th percentile = 0.8(N + 1) th variable = 0.8 × (15 + 1) = 12.8th variable = 13th variable = 285

Final answer:

To find the 25th and 80th percentiles for the reaction times, sort the list and determine the corresponding values.

Explanation:

To find the 25th and 80th percentiles for the reaction times in this experiment, we need to first sort the list in ascending order:

  1. 164
  2. 171
  3. 175
  4. 202
  5. 217
  6. 226
  7. 231
  8. 241
  9. 257
  10. 261
  11. 269
  12. 273
  13. 285
  14. 296
  15. 311

The 25th percentile is the value that separates the lowest 25% of the data. In this case, it is the 4th value in the sorted list, which is 202 milliseconds. The 80th percentile is the value that separates the lowest 80% of the data. In this case, it is the 12th value in the sorted list, which is 273 milliseconds.
