I believe it is Complimentary
-12/4= -3
18/5= 3.6
-2.5= -2.5
1/5= .2
10= 10
Ordered) -12/4, -2.5, 1/5, -2.5, 10
The median is 1/5 since it's in the middle of all five numbers.
Hope I could help! :)
Start off by doing
64/1000
that should equal 0.064
0.064 and quare it by 3
0.4
which equals 4/10
Answer:
I guess that you want to calculate the difference between the annual healt care costs in 1950 and today.
The equation is:
C(x) = $620*(1.082)^x
in 1950, we have x = 0 (because is the initial year)
then the cost is:
C(0) = $620*1 = $620.
Now, today, in 2020, we have:
x = 2020 - 1950 = 70
then we have:
C(70) = $620*(1.082)^70 = $154,276.7
So, according to this equation, te difference is:
$154,276.7 - $620 = $153,656.6
For the answer to the question above,
and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n
0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem
if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10
then I would stop here
because I didn't see the choices. So the answer is 4n
