I can't draw the graph, but I will give all needed information to be used to draw the Box Plot.

1st arrange the data from smaller to greater:
 
53   55   56   56   57   57   58   58   58   59   59   60   62  
|------------------|-----------------|----------------|-----------------|
Min               Q₁              Median             Q₃              Max

Data Range = 62 - 53 = 9
Minimum = 53
Q₁ = 56
Median = 58
Q₃ = 59
Maximum = 62

While working your Box Plot, follow the info given BY ORDER, the way I displayed them

Question is the attachment
astraxan [27]

If both pipes are opened. Then the number of hours to fill up the tank fully is 100 hours.

The complete question is attached below.

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Let t be the filling time.

Then we have

Time is inversely proportional to rate of filling tank.

1/20 – 1/25 = 1/t

0.05 - 0.04 = 1/t

          0.01 = 1/t

                t = 1/0.01

                t = 100 hours

More about the ratio and the proportion link is given below.

Write the polar equation as a set of parametric equations.<br><br> r=3sinθ<br> Show all work.
AVprozaik [17]

Answer:

x=t

y=\pm\sqrt{3t-t^2}

Step-by-step explanation:

The given polar equation is;

r=3\sin \theta

We multiply  both sides by r

r^2=3r\sin \theta

The corresponding rectangular equation is

y^2+x^2=3x

y^2=3x-x^2

y=\sqrt{3x-x^2}

Let x=t,

Then;

y=\pm \sqrt{3t-t^2}
