A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia

Alecsey [184]

Answer:

$D=13.8\ ft$

Step-by-step explanation:

we know that

If the tank half-filled with water is at 20 feet, then the height of the tank is 40 feet

The volume of the cylindrical tank is equal to

$V=\pi r^{2}h$

we have

$h=40\ ft$

$V=6,000\ ft^{3}$

assume

$\pi =3.14$

substitute and solve for r

$6,000=(3.14)r^{2}(40)$

$r^{2}=6,000/[(3.14)(40)]$

$r=6.9\ ft$

Find the diameter

Remember that the diameter is two times the radius

$D=6.9*2=13.8\ ft$

What is the interquartile range of the data?<br><br> I think the answer is B.

zhenek [66]

Answer:

No, correct option is (A) 117.5

Step-by-step explanation:

Interquartile range (IQR) measures the skewness using 50% of the data. It is the difference between the third quartile and the first quartile. i.e.

IQR = Q₃ - Q₁

For finding the Interquartile Range of the data:

100, 120, 130, 188, 196, 220, 265, 300

Divide the data into two parts:

(100, 120, 130, 188) (196, 220, 265, 300)

2. Now finding the medians of both halves of the data that will be our First and Third Quartile of data.

So, Q₁ = 125 and Q₃ = 242.5

Now, using IQR = Q₃ - Q₁

= 242.5 - 125 = 117.5

Hence, Correct option is Option (A).
