The median for the given set of six ordered values is 28.5
Alika [10]
X=the missing value

the median is the middle number, but in this case there are two which happens to be 25 and x
so the formula is

25+x/2=31.5
use algebra to solve
25+x=63
x=63-25
x= 38

Therefore, the missing value is 38.

Hope this helped. Let me know if you have any further questions:)

HELP PLEASEEEEEEE it’d be rlly appreciated
Alex_Xolod [135]

Answer: they have

et n = number of nickels

Let d = number of dimes

given:

(1) +n+%2B+d+=+45+

(2) +5n+%2B+10d+=+360+

-------------------

Multiply both sides of (1) by 5

and subtract (1) from (2)

(2) +5n+%2B+10d+=+360+

(1) +-5n+-+5d+=+-225+

+5d+=+135+

+d+=+27+

and, since

(1) +n+%2B+d+=+45+

(1) +n+%2B+27+=+45+

(1) +n+=+45+-+27+

(1) +n+=+18+

She had 18 nickels and 27 dimes

check:

(2) +5%2A18+%2B+10%2A27+=+360+

(2) +90+%2B+270+=+360+

(2) +360+=+360+
