Answer:
Step-by-step explanation:
The given equation is:
5x+15 =0
Subtract 15 from both sides:
5x+15-15= 0-15
By solving the like terms we get:
5x=-15
Divide both sides by 5
5x/5 = -15/5
Simplify:
x= -3...

Step-by-step explanation:
Given the data :
Technician __Shutdown
Taylor, T___4
Rousche, R _ 3
Hurley, H__ 3
Huang, Hu___2
Gupta, ___ 5
The Numbe of samples of 2 possible from the 5 technicians :
We use combination :
nCr = n! ÷ (n-r)!r!
5C2 = 5!(3!)2!
5C2 = (5*4)/2 = 10
POSSIBLE COMBINATIONS :
TR, TH, THu, TG, RH, RHu, RG , HHu, HG, HuG
Sample means :
TR = (4+3)/2 = 3.5
TH = (4+3)/2 = 3.5
THu = (4+2) = 6/2 = 3
TG = (4 + 5) = 9/2 = 4.5
RH = (3+3) = 6/2 = 3
RHu = (3+2) /2 = 2.5
RG = (3 + 5) = 8/2 = 4
HHu = (3+2) = 2.5
HG = (3+5) = 8/2 = 4
HuG = (2+5) / 2 = 3.5
Mean of sample mean (3.5+3.5+3+4.5+3+2.5+4+2.5+4+3.5) / 10 = 3.4
Population mean :
(4 + 3 + 3 + 2 + 5) / 5 = 17 /5 = 3.4
Population Mean and mean of sample means are the same.
This distribution should be approximately normal.

Step-by-step explanation:
x = -2
2 + x > -8
2 + -2 > -8
0 > -8
Answer:
26
Step-by-step explanation:
8+10+8=26
Answer:
5.50
Step-by-step explanation:
If three cones cost 8.25, then each cone should cost 2.75. (8.25 / 3 = 2.75)
Then 2 cones should cost 5.50 (2.75 x 2 = 5.50)
