Answer:
upper control limit = 6.058
lower control limit = 0.442
Step-by-step explanation:
Given that:
The numbers of sample n Mogul executives took = 8 Eagletrons at a time.
They find out that the average sample mean is 88.50 mph and;
the average range
is 3.25 mph.
From the tables:
![\text {Table values for n = 8 } \left \{ {{D_4=1.864} \atop {D_3=0.136}} \right.](https://tex.z-dn.net/?f=%5Ctext%20%7BTable%20values%20for%20n%20%3D%208%20%7D%20%5Cleft%20%5C%7B%20%7B%7BD_4%3D1.864%7D%20%5Catop%20%7BD_3%3D0.136%7D%7D%20%5Cright.)
Control Limit =
= 3.25
Therefore; the upper control limit and the lower control limit can be computed as follows:
upper control limit = ![D_4 \overline r](https://tex.z-dn.net/?f=D_4%20%5Coverline%20r)
upper control limit = 1.864(3.25)
upper control limit = 6.058
lower control limit = ![D_3 \overline r](https://tex.z-dn.net/?f=D_3%20%5Coverline%20r)
lower control limit = 0.136(3.25)
lower control limit = 0.442

4c+5.6d=1360
Let
Children (c)=x
Adults (d)=284-x
4x+5.6 (284-x)=1360
Solve for x
4x+1590.4-5.6x=1360
4x-5.6x=1360-1590.4
-1.6x=-230.4
X=230.4÷1.6
X=144 children
284−144=140 adults
Answer:
Step-by-step explanation:
The computation of the volume of the cylinder is shown below:
As we know that
The Volume of the cylinder is
= base × height
= (4x)^2 + (5x)^2
=16x^2 + 25x^2
= 41x^3
Hence, the volume of the cylinder is 41x^3
Answer:
15% of 60 is 9
Step-by-step explanation:
15%= 3/20
3/20*60= 180/20
180/20= 9
15% of 60 is 9
Hope this helps!
