Step-by-step explanation:
A). From the table of relative frequencies,
Let the relative frequency of women who prefer mineral water = x
Total of relative frequencies of women preferring purified water and mineral water = 0.59
Since, Total of relative frequencies of women who prefer purified water and mineral water = Relative frequency of women preferring purified water + Relative frequency of women preferring mineral water
0.59 = 0.14 + x
x = 0.59 - 0.14
x = 0.45
B). Relative frequency of men who prefer mineral water = 0.13
Let the frequency of men who prefer mineral water = x

0.13 =
x = 200 × 0.13
x = 26
Therefore, number of shoppers who are men and prefer mineral water = 26

Volume of square box = Area * height =
Differentiating the above equation and equating it to zero, we get –
d/dx
d/dx= d/dx
d/dx
On solving above equation, we get –
