Answer:
He wants to see if the proportion of the 125 tea-drinking employes is, as the newspaper report claims, 30%.
Then the null hypothesis says that this is false and that there is no relation between the events.
Then the null hypothesis is:
The proportion of all tea-drinkers at the company that prefer green tea to black the is not the 30%
Which is the negation of the thing that Leo wants to check.

Answer:
The perimeter of the figure is approximately 42.85.
Step-by-step explanation:
Based on the given values, you already know that two of the sides of the shape are 12 units long. Since the half-circle above the rectangle is the same size as the gap in the rectangle - you know this because both of the half-circle's diameter are 6 units long - so you can add 24 units to the perimeter of a circle with a diameter of 6. The diameter of the circle is 
, or approximately 18.85, so the perimeter of the whole figure is approximately 42.85.
The initial amount of water was 2.5 million liters
Then 2 million liters remained after evaporation, therefore 0.5 liters evaporated from the swimming pool.
Thus, the percentage will be given by: 0.5/2.5 × 100 = 20%
Hence the answer is 20%
