Eagletrons are all electric cars produced by Mogul motors. One of the concernsof Mogul is that the Eagletrons be capable of achieving appropriate maximumspeeds. To monitor this, Mogul executives take samples of 8 Eagletrons at atime. For each sample, they determine the average maximum speed and the rangeof the maximum speeds within the sample. They repeat this with 35 samples toobtain 35 sample means and 35 ranges. They find that the average sample mean is88.50 mph and the average range is 3.25 mph. Using these results, theexecutives decide to establish an R chart. They would like this chart to beestablished so that when it shows that the range of a sample is not within thecontrol limits, there is only approximately a .0027 probability that this is dueto natural variation. What will the upper control limit (UCL) and the lowercontrol limit (LCL) in this chart?
Trying to confirm that what I came up with is correct.
Answers
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 [tex]\overline r[/tex] is 3.25 mph.
From the tables:
[tex]\text {Table values for n = 8 } \left \{ {{D_4=1.864} \atop {D_3=0.136}} \right.[/tex]
Control Limit = [tex]\overline r[/tex] = 3.25
Therefore; the upper control limit and the lower control limit can be computed as follows:
upper control limit = [tex]D_4 \overline r[/tex]
upper control limit = 1.864(3.25)
upper control limit = 6.058
lower control limit = [tex]D_3 \overline r[/tex]
lower control limit = 0.136(3.25)
lower control limit = 0.442
The zeros of the quadratic x^2+4x=-2x+16 are x=-8 and x=2. What does this tell you about the graph of this quadratic function?
a. The parabola crosses the x-axis at x=-8 and x=2.
b. The parabola touches the x-axis only at and x=2.
c. The parabola does not touch or cross the x-axis.
d. The parabola crosses the x-axis at x=-8 and x=2 but you can ignore the zero x=-8 because it is negative.
Answers
The graph of the quadratic function x²+4x=-2x+16 is a parabola that crosses the x-axis at x=-8 and x=2. Correct option is (a).
What are zeros and graph of an quadratic equation?Let ax² +bx +c = 0 is an quadratic equation its zeroes are the values of x for which the Left hand side becomes zero.
To find zeroes we can use quadratic formula that is
x = (-b ±√(b²-4ac))/2
Graph of the quadratic equation are points ( x , y(x) )
where y(x) = ax² +bx +c
when x= t is zero of quadratic equation ax² +bx +c = 0
then y(t) = 0
(t, 0) points are points on the x-axis.
Given an quadratic equation
x²+4x=-2x+16 has roots x =-8 and x =2
This can we written as x² +6x -16 =0
The graph of this quadratic equation is given by (x, y(x))
where y = x² +6x -16 which is a parabola
for x= -8 and x= 2 , y(-8) =y(2) = 0
Then (-8,0) and (2,0) are points on this parabola which are at x-axis
Therefore, the parabola y = x² +6x -16 crosses the x-axis at x=-8 and x=2.Thus (a) is the correct option.

A football stadium holds 17,700 seats. The lower level has 300 seats less than 4 times the number of seats in the upper level. The middle level has 500 more seats than twice the number of seats in the upper level. Let x represent the seats in the upper level. Which equation can be used to find the number of seats in the upper level?
A.7 x + 200 = 17,700
B.6 x + 200 = 17,700
C.7 x minus 200 = 17,700
D.6 x minus 200 = 17,700
Answers
Answer:
C. 7x-200=17700
Step-by-step explanation:
When you write an equation for the middle and lower row you can add them together to get 6x+200=1700 but you still must include the upper row so you add x which results in c. If you solve you get x=2500 and if you plug that back into you equations for the lower and middle rows and then add the upper row you get 17700.
Answer:
7x+200=17,700 because if you set up an equation for each level, the upper level is just x, the middle level is 2x=500, and the lover level is 4x- 300. if you add all 3 equations together and set it equal to 17,700, it equals 7x+200=17,700

Step-by-step explanation:
The sum of interior angles of a polygon of n sides is:
[tex]S=180^\circ (n-2)[/tex]
The image shows a 6-side polygon. The sum of the interior angles is:
[tex]S=180^\circ (6-2)=720^\circ[/tex]
The sum of all the shown interior angles must equal 900°:
[tex]125+100+y+117+121+y+23=720[/tex]
Simplifying:
[tex]486+2y=720[/tex]
Solving:
[tex]2y=720-486[/tex]
[tex]2y=234[/tex]
[tex]y=234 / 2=117[/tex]

Step-by-step explanation:
∠ RST and 4x - 24 are alternate exterior angles and congruent, thus
4x - 24 = 3x ( subtract 3x from both sides )
x - 24 = 0 ( add 24 to both sides )
x = 24
Thus
∠ RST = 3x = 3 × 24 = 72°
