Given that the summary of the population is:
<span>Mean: 42
Median: 38
Range: 52
Mean Deviation: 11.23
To obtain the sample that is closest to the mean we shall proceed as follows:
Shift 1:
</span><span>18,25,56,42,29,38,54,47,35,30
The mean of the sample is:
(18+25+56+42+29+38+54+47+35+30)/10
=374/10
=37.4
Shift 2:
</span><span>23, 19, 50, 49, 67,34,30,59,40, 33
</span>The mean is:
(23+19+50+49+67+34+30+59+40+33)/10
=404/10
=40.4
Shift 3:
<span>Shift 3
19, 22, 24, 40, 45, 29, 33, 29, 39, 59
The mean of the values
</span>(19+22+24+40+45+29+33+29+39+59)/10
=339/10
=33.9
Shift 4:
<span>21, 23, 25, 40, 35, 19, 70, 40, 22, 23
The mean of the values is:
(</span>21+23+25+40+35+19+70+40+22+23)/10
=318/10
=31.8
From the calculations, the sample that has mean that is close to population mean is Shift 2
Answer:
Step-by-step explanation:
Because in equation x-9y=12
If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12
So, (12,0) make equation
(3,-1) also make equation
(3)-9(-1)=12
(0,-4/3) also make equation
Because
0-9(-4/3)=12
Only (0,12) is not making
Beacuse
(0)-9(12) is not equal to 12
Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³
