You can do volume=length times width times height for a perfectly rectangular pool

you can get lots of tennis balls and fill the pool with them and estimate the volume, that's how they measure the volume of wierd spaces in cars.

you can fill the pool with water and measure how many gallons in the pool then convert that to square feet

you can put a scanner (special type) and make a 3d rendering of the pool then measure the volume with the tools in the 3d program

Answer:

No. These measures show a thinner team of NFL players according to the mean, variance, standard deviation, and quartiles.

Step-by-step explanation:

1) The measures of variation, namely The Range, Variance, Quartiles, Interquartiles, Sum of Squares, etc. shows us how the data are dispersed.

The Range Δ is calculated:

$\Delta =305-189=116$ Maximum value - Minimum value for weight

Mean:

$\bar{x}=\frac{189+254+235+225+190+305+202+190+252+305}{11}\approx 231.09 \:pounds$

Variance:

$s^{2}=\frac{\sum_{i=1}^{n} (x_i-\bar{x})^{2}}{n-1}\Rightarrow s=1923.69\\$

The Standard Deviation of the sample

$s=\sqrt{s^{^{2}}}\Rightarrow s\approx 43.86\\$

2) Since there is no preceding exercise, the comparison was made to a recent study in which a NFL player average weight is about 245 pounds (average),

Since 25% of this list are player whose weight is 192.5 lbs and 50% (2nd Quartile) =225 lbs , finally only at the 3rd Quartile we have players above the regular NFL average with 253. This, added with the other data, allow us to say that this list is not a typical of all NFL players.

A store brought 9 cases of light bulbs in May and 8 cases in June. There are 48 light bulbs in a case. How many light bulbs did

UkoKoshka [18]

So the store bought 9 cases of lightbulbs and in a case, there are 48.
9 * 48 = the number of lightbulbs in the nine cases. 432 is the number of light bulbs in the 9 cases they bought in May. So then let's move on to the cases they bought in June. Do the same thing 8 * 48 is 384. So then add the two amounts together and then you will get 816 which will be your answer. I hope this helps!

I'm confused, can someone help?

To solve for S, you would want to get rid of the denominator so multiply 360 onto both sides. then the equation is 360A=pi times r squared times S. Divide both sides by pi and r squared and you get S=360A/pi times r squared

What is the graph of the direct variation equation? Y=5/2x

Aneli [31]

Given equation : y=5/2x.

Solution: In order to graph direct variation equation, we need to make a table of different values of x and y.

We need to plug some values of x's in equation to get values of y's.

Because, we have fraction 5/2, and 2 in denominator. So it would be better to take multiples of 2, so that we don't get values in decimals.

Let us take x=0 first.

Plugging x=0 in given equation, we get

y=5/2x = 5/2(0) = 0.

Let us take x=2 first.

Plugging x=2 in given equation, we get

y=5/2 *(2) = 5

Let us take x=2 first.

Plugging x=4 in given equation, we get

y=5/2 *(4) = 5 *2 = 10.

We got three coordinates for the graph (0,0) , (2,5) and (4, 10).

Let us plot those coordinates on the graph and join the points to draw a straight line.
