Answer:

Given: base = 10.4ft, height = 12.5

Area of octagon = 8(1/2 × b × h)

8(1/2 × 10.4 × 12.5)
520ft²

Volume of pool = 520ft² × 3ft

1560ft³

Now, 1 cubic ft takes 7.5 gallons to fill.

Therefore, 1560 cubic ft takes,

1560 × 7.5
11700

So, Correct choice - [D] 11,700.

What is an outlier mmkay

weeeeeb [17]

In statistics, an outlier is an observation point that is distant from other observations. These extreme values need not necessarily impact the model performance or accuracy, but when they do they are called “Influential” points. Note: An outlier is a data point that diverges from an overall pattern in a sample.

Wayne went on a 4km hike. He took a break at 4/3 k. He took a drink of water at 10/3. Show Wayne's hike on the number line. Incl

tamaranim1 [39]

1. The information given in this problem, is:

- Wayne went on a 4 km hike.
- Wayne took a break at 4/3 km.
- Wayne took a drink of water at 10/3.

2. Then, when you convert the values from fractions to decimals, you have:

4/3 km=1.33 km
10/3 km=3.33 km

3. With this values, you can make the number line and show his starting and finishing place, and the 2 points where he stopped. This is shown in the figure attached.
