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:
B
Step-by-step explanation:
Angle M is vertical to K, it is congruent. Angle E and C are corresponding angles to Angle M, which are angles positioned in the same direction. Angle E and C are congruent because they are the congruent to Angle M and Angle M is congruent to Angle K.
The options can be rewrited as follow:
A. 5<4
B. 5<5
C. 5<4
D. 4<-5
∴ Answer is none of the above.
Unless perhaps you have written down the question incorrectly.
Answer:
Step-by-step explanation:
The upper and lower angles are vertical angles, so congruent:
(5x -5)° = 55°
x - 1 = 11 . . . . . . . divide by 5°
x = 12
_____
The 55° angle and y° are a linear pair, so are supplementary.
y° = 180° -55°
y = 125 . . . . . . . simplify, divide by °
Answer:
y = 1/2
Step-by-step explanation:
-20y + 15 = 2 - 16y + 11
Add 16y to get -4y + 15 = 2 + 11, or -4y + 15 = 13
Subtract 15 to get -4y = -2
Divide by -4 to get y = 1/2
