How do you find the median of 15,8,19,21,18,17 ? Thanks

KengaRu [80]

Answer:

median = 17.5

Step-by-step explanation:

The median is the middle value of a data set arranged in ascending order. If there is not a middle value then the median is the average value of the numbers either side of the middle.

Data in ascending order is

8, 15, 17, 18, 19, 21

The median is between 17 and 18, hence

median = $\frac{17+18}{2}$ = 17.5

V = 1/3* h * r^3 pi
V ' = 1/3* h/3* (2r)^3 pi = h/9 * 8r^3 * pi

V ' / V = (h/9 * 8r^3 * pi) ÷ ( 1/3* h * r^3 pi ) = (8 * 3)/ 9 = 8 /3

Help me please!! I am so confused!!

Gwar [14]

Answer:

(4,1), (-4,1), (4,6), (-4,6)

Step-by-step explanation:

Here can be identified two points with the same 'y' value: (4,1), (-4,1)

it means that there is a line passing by y=1

Same for (4,6), (-4,6): it means that there is a line passing by y=6

Now find the distance between two points in both cases

Please answer soon I need this answer very quickly for math. Thank you!

Kazeer [188]

a. First five terms: 9,13,17,21,25

b. Sum of first 25 terms = 1425

c. The given sequence is an arithmetic sequence because the common difference between two consecutive terms is same.

Further explanation:

Given

Formula of sequence

$a_n=4n+5$

1. First 5 terms:

For first 5 terms, we have to put n=1,2,...5,

So,

$For\ n=1\\a_1=4(1)+5\\=4+5\\=9\\For\ n=2\\a_2=4(2)+5\\=8+5\\=13\\For n=3\\a_3=4(3)+5\\=12+5\\=17\\For\ n=4\\a_4= 4(4)+5\\=16+5\\=21\\For\ n=5\\a_5=4(5)+5\\=20+5\\=25\\First\ 5\ terms\ are: 9,13,17,21,25$
