The median of the set (n, n+5, n+6, n+9, n+15) is 9. What is the mean?
1 answer:
Answer:
=9.4
Step-by-step explanation:
The median is the middle of the numbers when lined up from smallest to largest
(n, n+5, n+6, n+9, n+15)
The median is n+6
n+6 = 9
Subtract 6 from each side
n +6-6 = 9-6
n = 3
The numbers are
(n, n+5, n+6, n+9, n+15)
3, 8 ,9 ,12, 15
The mean is where you add up all the numbers and divide by the number of numbers
mean = (3+8+9+12+15) /5
= (47)/5
= 9 2/5
=9.4

so the answer is 0.8
Substitute the variable for the value given.
11 - 3m becomes 11 - 3(2)
Now do the order of operations.
11 - 3(2) =
11 - 6 =
5
So, the answer is 5.
2x+4-3x>-1
-x+4>-1
-x>-1-4
-x>-5
X<-5/-1
Hence x<5
Yeah, dude it sure is.
I'm assuming you wanted something like this?
40x + 4.5y = 112
x = Days
y = Pairs of shoes
112 = Total profits
