Part ii
I'm not sure that one's typed in correctly but I'll solve it as written.
We're not asked to simplify it so I wont. Substituting,
Answer: 59/306
Answer:
its C
Step-by-step explanation:
Answer:
They would be -104 and -103.
Step-by-step explanation:
-103 + (-104)
= -103 - 104
= -207.
X f πxf
-1 2 -2
3 1 3
-1 -2 2
0 -3 0
total =3
mean (π)=πxf ÷n
= 3÷4
= 0.75 these is not answer I thank so
So you know that he earns $15 per hour so we can write that as 15h, h = # of hours worked
We also know he has to earn AT LEAST $200, so putting all this together we form the inequality(=< means less than or equal to): 15h =< 200
so now we have to solve for h (number of hours worked):
15h =< 200
(divide both sides by 15)
h =< 13 1/3
So, the painter must work a minimum of 13 and 1/3 hours to earn at least $200.
