I’m guessing 1/2 since he spent “half” her money
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
Answer: 8x + 20y
Step-by-step explanation:
Since there is no answer after =, I'll assume you have to give your own.
![4(2x+5y)=?](https://tex.z-dn.net/?f=4%282x%2B5y%29%3D%3F)
![(4*2x)+(4*5y)=?\\8x+20y](https://tex.z-dn.net/?f=%284%2A2x%29%2B%284%2A5y%29%3D%3F%5C%5C8x%2B20y)
