One Answer: Choice C) 0 < x < 1
==================================================
Explanation:
Let's go through the answer choices one at a time.
- Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.
- Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.
- In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.
- Choice D is false because choice C was shown to be true.
Answer:
C. approximately 99.99%
Step-by-step explanation:
The distribution bell shape is a normal distribution, with mean 120 mmHg and standard deviation 12 mmHg.
The rank between 96 mmHg and 144 mmHg is wider than the rank between mean plus, minus 3 standard deviation (102 mmHg up to 138 mmHg), and this rank is approximately 99.7 %.Therefore 99.99 % includes more closely values in the rank 96 up to 144 mmHg
