Which expression below is an equivalent expression to: (13n^4+12n^3-3+8n^2)+(-11n^2-n^3)

Lubov Fominskaja [6]

Answer:

-13n^4 + 11n^3 - 3n^2 - 3

Step-by-step explanation:

*I think you mistyped the question. I belive the 13n^4 is supposed to be negative*

1.First, we need to add common values (all the n^4s together, all the n^3s, etc.) from the two sets.

-13n^4

12n^3 + -n^3

8n^2 + -11n^2

-3

2. Now lets simplify

-13n^4

11n^3

-3n^2

-3

3. Laststly, we put them all into one expression!

-13n^4 + 11n^3 - 3n^2 - 3

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.
