Answer:

Step-by-step explanation:

first you put the numbers in order from least to greatest

1,1,1,1,2,2,2,4,12,13,15,15,15,16,16

next find the middle number(s)

1,1,1,1,2,2,2,<em>4</em>,12,13,15,15,15,16,16

the middle number is your median

*if you have 2 middle numbers just add the then divide it by 2 to find the median

Katherine wants to construct a small box with a volume of 20 cubic inches with the following specifications. The length of a box

pochemuha

V=LWH=20

L is 5 more than W
V=5+W

H is 1 less than W
H=-1+W

easy, sub 5+W for L and -1+W for H in LWH=V=20

20=(5+W)(W)(-1+W)
expand
20=W^3+4W^2-5W
minus 20 both sides
W^3+4W^2-5W-20=0
either factor or graph to find the possible values for W
(W+4)(W^2-5)=0
set each to zero

W+4=0
W=-4
impossible, measures cannot be negative
W^2-5=0
add 5
W^2=5
sqrt both sides
W=√5

sub back

L=5+W
L=5+√5
aprox
7.24 rounded

H=-1+W
H=-1+√5
aprox
1.24 rounded
the dimentions are
√5 by (5+√5) by (-1+√5) or aprox
2.24in by 7.24in by 1.24in
