10 is the size of the sample when it was originally found
For this case we must solve a system of two equations with two unknowns, given by "x" and "y".
We have:
We multiply (2) by -1:
We add (1) and (3):
Clearing x:
We substitute in (2)
Thus, the solution of the system is
Answer:
The solution of the system is
Answer:
x=14
y=10
Step-by-step explanation:
The median divide the data‘s set into two parts with the same frequency = 50%
then we must have 2+5+x+12+17 = 50 ⇔ 36+x=50 then x =50-36=14
also 20+y+9+7+4=50 ⇔ y=10
Answer:
1.06c
Step-by-step explanation:
c+0.06c=c(1+0.06)=c(1.06)=1.06c
