Answer:
Step-by-step explanation:
so why this kind of problem is so confusing is b/c it's 2 problems in one
if you were to expand this it look like this
10 ≤2x
and
2x ≤x+9
This is really saying.. that x has a range.. and that the 1st equations is the lower stop point, and that the 2nd equations is the upper stop point
once it's taken apart.. I bet you can solve it pretty quickly.
5≤x
and
x ≤9
then just put it back together in that confusing .. yet handy way to write it,
5≤x≤9

Answer:
4.3
Step-by-step explanation:
mean=sum of the terms/number of term
room A=3+20+25+0+0+0=25
Room B= 2+18+4+0+0+0=24
room C= 28
room D= 21
room E= 32
step(2)
25+24+28+21+31=130/30
= 4.3
