5. Use the given process data to construct a control chart for p.
A manufacturer monitors the level of defects in the television sets that it produces. Each week, 200 television sets are randomly selected
and tested and the number of defects is recorded. The results for 12 consecutive weeks are shown below.
4756831244562
Select the correct lower control limit.
lower control threshold for the data is LCL = -0.007
How does lower control limit work?The lower control limit on a control chart is the value below which any particular data point would be deemed to be out of statistical control owing to specific cause variation. It is represented by a line below the centerline.
The lower control limit formula: LCL = Pbar - [tex]3 \sqrt{p bar (1- p bar)/n}[/tex]
To date,
Size of sample = n
Sample size is 12 samples.
Televisions with defects = X
We have a sample defect = p
p chart week with n = 200
x = 4, 7, 5, 6, 8, 3, 12, 4, 4, 5, 6, 2.
P = x/n
p = 4/200 = 0.02
p = 7/200 = 0.035
p = 5/200 = 0.025
p = 6/200 = 0.03
p = 8/200 = 0.04
p = 3/200 = 0.015
p = 12/200 = 0.06
p = 4/200 = 0.02
p = 4/200 = 0.02
p = 5/200 = 0.025
p = 6/200 = 0.03
p = 2/200 = 0.01
total will be 0.33
p bar = 0.33/12
p bar = 0.0275
The lower control limit formula: LCL = Pbar - [tex]3 \sqrt{p bar (1- p bar)/n}[/tex]
LCL = 0.0275 - 3[tex]\sqrt{ 0.0275 (1- 0.0275/200}[/tex]
LCL = -0.007

if the a horizon in a soil sample measures 3 inches, and the rate of top soil for temperate deciduous forest (where the soil was sampled) is 1 in/225 years, how long did it take for this horizon to develop?
The time taken by the horizon to develop is calculated with the half-life which is 675 years.
Organic matter particles have more negatively charged particles, which hold on the positively charged particles.
The organic matter in the soil affects the water holding capacity of the soil. Thus is if there are more organic matter, this means that the organic matter is more. Thus the farmer has to add more organic matter.
In order to reduce the the acidity, the farmers add Calcium oxide, Calsium hydroxide and so on.
The horizon s formed after years of sediment formation. Thus the process can take years.
This is the half-life of the soil and with the formula of half-life we get 225 * 3 = 675 years.
Therefore, the time taken by the horizon to develop is 675 years.

What is Turning Point?Where a graph changes, either from increasing to decreasing, or from decreasing to increasing, is called a turning point.
How to find Turning Point?Factorization Technique
The turning point of the parabola lies exactly at the midway between the (two) x-intercepts of a quadratic function, as shown by the fact that a vertical line of symmetry divides the parabola into two equal half and crosses it. In light of this, we can use a factorisation-based method to locate the solution of a quadratic equation. The process involves five steps.
Step 1: By looking at the coefficient of x2, determine if the graph is a minimum or maximum;
Factorize the supplied quadratic function in Step 2 and set it to Zero;
Step 3: Define the function's antecedents;
Take the midpoint of the pair of roots to find the x-coordinate of the turning point in step 4;

Line L is the perpendicular bisector of segment WY, Z is a point on L.
NIcholas noticed that WXZ and YXZ are congruent based on side-angle-side congruency postulate.
What theorem can we prove using these congruent triangles?
Choose 1 answer:
A. Vertical angles are congruent.
B. Measures of interior angles of a triangle sum to 180\degree180°180, degree.
C. A point on the perpendicular bisector of a line segment is equidistant from the segment’s endpoints.
D. Any line segment is congruent to itself because every point on the segment maps to itself.
Given that WXZ and YXZ are congruent based on side-angle-side congruency, we can prove the theorem that states "A point on the perpendicular bisector of a line segment is equidistant from the segment’s endpoints." This theorem is often referred to as the "Perpendicular Bisector Theorem."
The required details for "Perpendicular Bisector Theorem" in given paragraph
The Perpendicular Bisector Theorem states that if a point is on the perpendicular bisector of a line segment, then it is equidistant from the segment's endpoints. This means that if we draw a line through a point that is perpendicular to a line segment, and that line passes through the midpoint of the segment, then the point is equidistant from the endpoints of the segment. In this case, we are given that line L is the perpendicular bisector of segment WY, and that Z is a point on L. We are also told that WXZ and YXZ are congruent based on side-angle-side congruency. Since WXZ and YXZ are congruent, it follows that WX and YX are congruent and that WZ and YZ are congruent. This means that the distances from Z to W and Y are equal, so Z is equidistant from W and Y.
Therefore, we can conclude that Z is a point on the perpendicular bisector of segment WY, and the Perpendicular Bisector Theorem is proved. The answer is C. "A point on the perpendicular bisector of a line segment is equidistant from the segment’s endpoints."

how far is the end of his shadow from the bottom of the lamppost after 8 seconds. use similar triangles to solve the problem
The Distance from bottom of lamppost is 57.142 ft.
What are similar triangles?Triangles with the same shape but different sizes are called similar triangles. Examples of similar objects include squares with any side length and all equilateral triangles. To put it another way, if two triangles are similar, their angles are the same and their sides are the same size. The "~" symbol indicates the triangular resemblance here.
Given the height of lamp post is 20 ft
height of man is 6 ft
man walking away with speed of 5 ft per sec
distance covered 8 sec is 8 x 5 = 40 ft
let us consider a triangle ΔABC and consider the triangle with man ΔDEC
which is inside ΔABC as shown in figure,
AB = 20 ft, DE = 5 ft and AD = 40 ft
consider ΔABC and ΔDEC
∠BAC = ∠EDC = 90⁰
∠BCA = ∠ECD = common angle
so ΔABC ~ ΔDEC by (AA property)
according to similar triangles
AB/DE = AC/DC
let DC be x and AC is 40 + x
substitute the values
20/6 = (40 + x)/x
20x = (40 + x)6
20x = 240 + 6x
14x = 240
x = 17.142ft
AC = AD + DC = 40 + 17.142 = 57.142 ft
Hence the Distance from bottom of lamp post to the end of shadow is 57.142 ft.

A.) $8.20
B.)$6.60
C.)$1.48
D.)$14.80
(Please pick one)
Mr. Henderson paid a total of $98.40 for phone service and $79.20 for garbage pickup last year. To find his average cost per month for these two services, we need to divide the total amount he paid by the number of months in a year.
Since there are 12 months in a year, we can divide the total amount Mr. Henderson paid for phone service and garbage pickup by 12 to find his average cost per month. This is calculated as follows:
Average cost per month = (98.40 + 79.20) / 12
Average cost per month = 177.60 / 12
Average cost per month = $14.80
Therefore, Mr. Henderson's average cost per month for phone service and garbage pickup last year was $14.80. This means that, on average, he paid about $14.80 per month for these two services.
