Monthly Sales Goals (in thousands)
Stem: Leaf
1 2 5 5 8
2 4 4 6
3 4 6
4 7 8 9

What is the mean monthly sales goal? (And try explain why so I can understand as well?)
a) 15000
b)24000
c)25000
d)29000

Answer 1

each stem represents a "10" spot, each leaf is a "1" spot

stem leafs
1 2 5 5 8

represents: 12, 15, 15, 18

or simply, 10+2, 10+5, 10+5, 10+8 for a row value of: 10(4)+(2+5+5+8)

Answer 2

the mean is still determined as the sum of the parts, divided by how many parts there are

Answer 3

10(4) + (2+5+5+8)
20(3) + (4+4+6)
30(2) + (4+6)
40(3) + (7+8+9)
^^
there are (4+3+2+3) total parts

Answer 4

I don't think I really get it fully. I added those four parts and divided and ended up with 87?

Answer 5

what did you get for the addition of the parts?

Answer 6

60
74
70
144

Answer 7

10(4) + (2+5+5+8)
20(3) + (4+4+6)
30(2) + (4+6)
40(3) + (7+8+9)


40 + (18)
60 + (14)
60 + (10)
120 + (24)
-----------
280 + 66 = 346

(4+3+2+3) = 12

my head adding might be a bit off, but i still get pretty close to an option: 346/12

Answer 8

20, not 18 lol, im 2 off

348/12 = 29

Answer 9

So it would be d) 29, right

Answer 10

Answer 12
