Answer:
You would click (1,-5)
Step-by-step explanation:
The absolute minimum is the lowest point of the graph.
In all graphs, if it says minimum, it almost certainly means that lowest point, and if there are more than one, you would simply click on those.
It does not matter how many points there are, only that they are the lowest.
Therefore, it would be 1,-5.

Answer:
d) 65.9 in < μ < 67.1 in.
Step-by-step explanation:
Given that a 99% confidence interval (in inches) for the mean height of a population is 65.7 < μ < 67.3
Mean = average of 65.7 and 67.3 = ![66.5](https://tex.z-dn.net/?f=66.5)
i.e. here margin of error =![67.3-66.5=0.80](https://tex.z-dn.net/?f=67.3-66.5%3D0.80)
For 99% confidence interval critical value is 2.58
Hence std deviation = ![\frac{0.8}{2.58}](https://tex.z-dn.net/?f=%5Cfrac%7B0.8%7D%7B2.58%7D)
For 95% confidence interval critical value is 1.96
Margin of error = ![1.96*\frac{0.8}{2.58}\\=0.607752](https://tex.z-dn.net/?f=1.96%2A%5Cfrac%7B0.8%7D%7B2.58%7D%5C%5C%3D0.607752)
Hence confidence interval = ![(66.5-0.6, 66.5+0.6)\\= (65.9, 67.1)](https://tex.z-dn.net/?f=%2866.5-0.6%2C%2066.5%2B0.6%29%5C%5C%3D%20%2865.9%2C%2067.1%29)
d) 65.9 in < μ < 67.1 in. is right
EXPLANATION
Let's see the facts:
The scale is---> 14 milimeters ----> 5 meters
Width = 42 milimeters
Applying the unitary method, the actual width of the pool is:
![Actual_{}width=42\text{ mm}\cdot\frac{5m}{14\text{ mm}}=15m](https://tex.z-dn.net/?f=Actual_%7B%7Dwidth%3D42%5Ctext%7B%20mm%7D%5Ccdot%5Cfrac%7B5m%7D%7B14%5Ctext%7B%20mm%7D%7D%3D15m)
The width of the pool is 15m
