#1 Answer:

The median height of giraffes is:

18 feet.

Step-by-step explanation:

We are given height, in feet, of 9 giraffes as:

           18, 16, 22, 14, 17, 19, 15 ,19,22

Now to find the median height of giraffes in the zoo we need to arrange the given data set in ascending order as:

14     15     16   17    18     19    19    22    22

Now we know that median is the central tendency of the data i..e it lie in the middle of the data set.

The value that lie in the middle of the given data set is:

18.

Hence, the median height of giraffes is:

18 feet.

#2 Answer:

The median of the sizes of the four parks is:

                        Option: C    33 acres.

Step-by-step explanation:

We are given area of four parks as:

27 acres    30 acres      34 acres      49 acres.

We know that the median of a data is the central tendency of a data and always lie in between or middle of the data set.

Hence, here the median will lie between 30 and 34

and hence is calculated as:

[tex]Median = \frac{30+34}{2}[/tex]

[tex]Median = \frac{64}{2}[/tex]

[tex]Median = 32[/tex]

which is close to 33.

Hence, the median size of the park is:

                             33 acres.

Answer:

$1.71

Step-by-step explanation:

if you were to multiple 1.9 by 6 you get the cost for if you were to by 6 cans separate which comes out to 11.40. but if you buy a pack you can take 15 percent off so you find 15 % of 11.40. which you would get 9.69. Then you minus the six can price from the pack price to find how much you save.

Answer:

length x width x height

Step-by-step explanation:

I'm 43

Answer:

Length x height x width.

Step-by-step explanation:

Examples:

1 x 2 x 3 = 1 x 2 = 2 + 0 = 2 x 3 = 3 + 3 = 6 so the answer is 6.

2 x 3 x 2 = 2 x 3 = 3 + 3 = 6 x 2 = 6 + 6 = 12 so the answer is 12.

Here's one more in a different way:

3 x 5 x 4 = 5 + 5 + 5 = 15 = 15 + 15 = 30 x 2 = 30 + 30 = 60.

Answer:

[tex]k^4+10k^2+21[/tex]

Step-by-step explanation:

[tex]k^2 (k^2)[/tex] is the same as saying [tex](k)(k)(k)(k)[/tex] and so it'll be [tex]k^4[/tex]. Combine [tex]7k^{2}[/tex] and [tex]3k^{2}[/tex] by adding them both to get [tex]10k^{2}[/tex]. Then multiply 7 by 3 to get 21. Therefore the area of the entire rectangle written in standard form as a polynomial is [tex]k^4+10k^2+21[/tex]. Write the polynomial with the highest degree being first to the lowest degree and that's how you write the polynomial properly.
