The three sigma control limits range from 0 to 8.20 for this size inspection limit and The probability of a type I error is 0.0038.
The inspection unit calculator in this case is 2
1.5 non-conformities on average per machine
Consequently, we would typically discover 2 * 1.5 = 3 non-conformities.
Here, C equals 3.
Lower Limit = C - 3 * c, which equals 3 - 3 * sqrt (3), which results in -2.19 (impossible), therefore 0
Reduced Limit = 0
Upper Limit: 8.20 when C + 3 * с + 3 + 3 * sqrt(3)
In this case, the three sigma control limits range from 0 to 8.20 for this size inspection limit.
(b) Type I errors happen when non confirmations go above the acceptable range.
This is a POISSON (3)
P(c > 8.20) = -1 POISSON (8, 3, true)
=1 - 0.9962
= 0.0038
In this case, the probability of a type I error is 0.0038.

Hello, I just need help with part b and it's dealing with combinations
According to the combination method, there are 6 ways for the selection to be made if one worker is to be a receptionist, one a secretary, and one a technical typist.
Combinations:
A combination is all about grouping. The number of different groups which can be formed from the available things can be calculated using combinations.
The standard form for calculating the combinations is,
[tex]^{n}C_{r}=\frac{n!}{r!(n-r)!}[/tex]
where,
0 ≤ r ≤ n.
This formula is sometimes also called as ncr formula.
Given,
An executive hires 3 office workers from 8 applicants.
Here we need to find how many ways can the selection be made if one worker is to be a receptionist, one a secretary, and one a technical typist.
Here we have to split the problem like the following,
We know that the total number of office workers is 3.
Like, if one worker is to be a receptionist, the the combination is like,
So, the value of n = 3 and r = 1.
Then, according to the ncr formula,
=> ³C₁ = [tex]\frac{3!}{1!(3-1)!}[/tex]
=> 3!/1!2!
=> (3 x 2 x 1) / 1 x 2 x 1
=> 3
Similarly, if one worker is to be a secretary,
Here the value of n = 2 (Because we have already select one person as receptionist) and r = 1
So,
=> ²C₁ = (2!)/1!(2-1)!
=> (2x1)/ 1 x 1
=> 2
Similarly, if one worker is to be a technical typist,
Here the value of n = 1 (Because we have already select one person as receptionist) and r = 1
So,
=> ¹C₁ = 1
Therefore, the total number of possible ways are,
=> 3 x 2 x 1

How does the graph of 2y−x=1 compare with the graph of 3y−x=1?
a.
The graph of 2y−x=1 has a steeper slope than the graph of 3y−x=1.
b.
The graph of 3y−x=1 has a steeper slope than the graph of 2y−x=1.
c.
The graph of 2y−x=1 crosses the x-axis farther to the left than the graph of 3y−x=1.
d.
The graph of 2y−x=1 crosses the x-axis farther to the right than the graph of 3y−x=1.
The way in which the graph of 2y − x = 1 compare with the graph of 3y − x = 1 is that: A. the graph of 2y − x = 1 has a steeper slope than the graph of 3y − x = 1.
What is a steeper slope?In Mathematics, a steeper slope simply means that the slope of a line is bigger than the slope of another line. This ultimately implies that, a graph with a steeper slope has a greater (faster) rate of change in comparison with another graph.
How to interpret the slope?Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
x and y are the points.m is the slope or rate of change.c is the intercept.For the graph of 2y − x = 1, the slope is given by:
2y − x = 1
2y = x + 1
y = x/2 + 1/2
Slope, m₁ = 1/2 or 0.5.
For the graph of 3y − x = 1, the slope is given by:
3y − x = 1
3y = x + 1
y = x/3 + 1/3
Slope, m₂ = 1/3 or 0.3.
Therefore, m₁ > m₂ (steeper slope).

A 12-ft-by-15-ft rectangular swimming pool has a 3-ft-wide no-slip surface around it. What is the outer perimeter of the no-slip surface?.
The outer perimeter of the no-slip surface is equal to 78 feet.
Perimeter is a term used to describe the sum of the outside edge lengths or it can also be described as the whole of the outer edge or boundary.
The outer perimeter of this swimming pool can be determined by adding 3 feet twice to all the sides of the rectangular swimming pool and then adding these sides together.
Since it is a 12-ft-by-15-ft rectangular swimming pool, this means that two sides of this swimming pool are 12 feet and two sides of this pool are 15 feet, therefore;
12 + 6 = 18
15 + 6 = 21
Now the perimeter can be determined by adding all the sides as follows;
18 + 21 + 18 + 21 = 78 feet
Hence, the outer perimeter of the no-slip surface is calculated to be 78 feet.

Ben earned 625.5 points out of 700 on an essay and 65out of 70 on an assignment. In order to earn an A in theclass, he needed to average a 91 on these twoassignments. Did Ben earn an A?
We were told that Ben earned 625.5 points out of 700 on an essay. Expressing his score in the essay in terms of percentage, it becomes
625.5/700 x 100 = 89.29%
Also, he scored 65 out of 70 on an assignment. Expressing his score in the assignment in terms of percentage, it becomes
65/70 x 100 = 92.86%
We would find the average between the two percentages
Average = sum of percentages/number of percentages
Average = (89.29 + 92.86)/2
Average = 91.075
Average is approximately 91%
Since in order to earn an A in the class, he needed to average a 91 on these two

The measure of angle UVX is 30°
What is an angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves. Angle can also refer to the length of a rotation or an angle. The arc is centered at the vertex and defined by the sides in the case of a geometric angle.
Given, measure of angle UVW = 72°
measure of angle XVW = 42°
So, the measure of angle UVX = 72° - 42° = 30°

find the trig graph equation
Step-by-step explanation:
I assume, based on what I see, that the solid line is just cos(x), right ?
and we need to find the equation that draws the dotted line, correct ?
the notation is strange, as it seems we need to find a multiplication factor for x in the cos function.
but there is no multiplication factor that moves the cosine wave by pi to the left or to the right (so that the max. happens, where originally the minimum happens, and vice versa).
so, we need to add (or subtract) pi in the cosine function.
the rest is clear :
the normal distance between min. and max. of the cosine function is 2 (between +1 and -1). the target is 4. so we need to multiply by 2.
and since the values of that function have to be between -4 and 0 (instead of -2 and +2), we have to subtract overall 2.

What are angles in parallel lines?
Angles in parallel lines are angles that are created when two parallel lines are intersected by another line. The intersecting line is known as transversal line.
We can conclude three factors determining parallel lines ,
Alternate angles are equal
Corresponding angles are equal
Co-interior angles add up to 180°
Same side exterior angles are supplementary
Given data ,
Let the first angle be represented as A
Now , the value of A is = ( 2x - 15 )°
Let the second angle be represented as B
Now , the value of B is = ( 3x + 5 )°
The angles A and B are on the same side of the exterior angles
And , lines a and b are parallel
So , When two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the same side of the transversal line are supplementary
Substituting the values in the equation , we get
( 2x - 15 )° + ( 3x + 5 )° = 180°
On simplifying the equation , we get
2x - 15 + 3x + 5 = 180
5x - 10 = 180
Adding 10 on both sides of the equation , we get
5x = 190
Divide by 5 on both sides of the equation , we get
x = 190/5
x = 38
Therefore , the value of x is 38
Hence , the value of x from the equation is 38
