I'm assuming that you are talking about sequences <3

In the context of a recursive formula where we have "n-1" in sub-index of "a", you can think of "a" as the previous term in the sequence. In the context of an explicit formula like "-5+2(n-1)" "n-1" represents how many times we need to add 2 to the first term to get the nth term.

Dw if you don't understand, sequences and functions isn't an easy topic

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.

Which is true of a geometric plane? A) one-dimensional B) two-dimensional C) three-dimensional D) no dimensions, only position

Sedbober [7]

Answer:

The correct option is B.

Step-by-step explanation:

A plane extends infinitely in two dimensions. It has no thickness.The plane has two dimensions: <u>length and width</u><u>.</u> But since the plane extends infinitely,the length and width cannot be measured.

Lets take an example of a flat sheet of metal. Imagine a flat sheet of metal. Now make it infinitely large in both directions. This means that no matter how far you go, you never reach its edges. Now imagine that it is so thin that it actually has no thickness at all. In spite of this, it remains completely rigid and flat. This is the 'plane' in geometry.
