I think a) would be the answer. I proceeded by elimination: the domaine of the function goes from 3 and continues to infinity, so that leaves with a) and b) as possible answers. Both have the same range and both of their functions reflect over the x axis, so we have to compare the two answer by looking at the position of the function in the graph. The function is in the first quadrant (top right corner), so the position of the function has to be at our right, which leads us to a).

The penguins currently living on an island are of two types, Chinstrap penguins and Gentoo penguins. The range of the heights of

velikii [3]

Answer:

The answer is "Option A"

Step-by-step explanation:

Using the range difference to calculate the maximum and minimum value.

The range of the chinstrap penguins are:

$R(c) = Max(c) - Min(c) = 13.2$

The range of the Gentoo penguins are:

$R(g) = Max(g) - Min(g) = 15.4$

For point A:

$Max(c) = x\\\\Max(g) = x + 5.8\\\\R(c) = x - Min(c) = 13.2 \to x = 13.2 + Min(c)\\\\R(g) = x + 5.8 - Min(g) = 15.4 \to x = 9.6 + Min(g)$

equate both of them

$13.2 + Min(c) = 9.6 + Min(g)Min(g) - Min(c) = 3.6$

It indicates that Min(c) surpasses Min(g), whereas Max(g) exceeds Max (c).

Therefore, the Max is picked for g for all penguins and the minimum is picked for c.

Range of all penguins $= Max(g) - Min(c) = x + 5.8 - x + 13.2 = 19$

Therefore, it will be determined as the option.

For point B:

In estimating the range the median height cannot help.

For point C:

In order to calculate the variety, the connection between both the mean height cannot be sued.
