Answer:
The pool can contain <u>4521.6 gallons</u> of water.
Step-by-step explanation:
Given:
The diameter of the cylindrical swimming pool = 16 feet.
And the height of the cylindrical swimming pool = 3 feet.
(1 ft³ = 7.5 gallons)
Now, to find the gallons of water the pool can contain.
So, we find the radius first:
Radius (r) = =
Height (h) = 3 feet.
Now, to get the volume of swimming pool which is cylindrical in shape by putting formula (using the value of π = 3.14):
<em>Thus, getting the volume of pool 602.88 feet³.</em>
<em>As, given 1 ft³ = 7.5 gallons</em>.
Now, to get the gallons of water the pool can contain we multiply the volume of pool by 7.5:
Therefore, the pool can contain <u>4521.6 gallons</u> of water.
Answer:
The minimum percentage of recently sold homes with prices between $197,200 and $232,800 is 75%.
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by .
In this question:
Mean of $215,000, standard deviation of $8900.
What is the minimum percentage of recently sold homes with prices between $197,200 and $232,800?
215000 - 2*8900 = 197200
215000 + 2*8900 = 232800
Within 2 standard deviations of the mean, so:
The minimum percentage of recently sold homes with prices between $197,200 and $232,800 is 75%.
