Question:
Several ratios are graphed below. Which ratio is not equivalent to the others?
Answer:
The ratio of 4 to 7 is not equivalent to others.
Step-by-step explanation:
- <em>Connect the points by a straight line.</em>
<em />
- <em>Equivalent points lie on the straight line</em>
<em />
- <em>The given graph is in the Attachment</em>
<em />
- <em>The (4, 7) doesn't lie on the straight line when the other three points lie on the line.</em>
<em></em>
<u><em>Hence (4, 7) is not equivalent to (2, 3), (6, 9), and (8, 12) </em></u>

Answer:
[34,54]
Step-by-step explanation:
-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.
Where:
- 68% is the first standard deviation
- 95% is the second standard deviation about the mean
- 99.7% is the 3rd standard deviation about the mean.
-Therefore. the middle 95% interval is calculated as:
Hence, the interval is [34,54]
