To assemble a piece of furniture, a wood peg must be inserted into a predrilled hole. Suppose that the diameter of a randomly selected peg is a random variable with mean 0.25 inch and standard deviation 0.006 inch and that the diameter of a randomly selected hole is a random variable with mean 0.253 and standard deviation 0.002. Let x1= peg diameter, and let x2= denote hole diameter.Why would the random variable , defined as y=x2-x1 , be of interest to the furniture manufacturer?What is the mean value of the random variable y?Assuming that x1 and x2 are independent, what is the standard deviation of y?Is it reasonable to think that x1 and x2 are independent? Explain.Based on your answers to Parts (b) and (c), do you think that finding a peg that is too big to fit in the predrilled hole would be a relatively common or a relatively rare occurrence? Explain.
(a) Using y the manufacture can find the required diameter of the hole.
(b) The mean of the random variable y is 0.003.
(c) The standard deviation of the y is 0.0063.
(d) It is reasonable to assume that x1 and x2 are independent since peg and hole are made of different wood.
(e) We can see that mean of y is greater than standard deviation of y, So mostly the peg maybe bigger than hole.
Given that x1 be the peg diameter with mean 0.25 in. and standard deviation 0.0006 in.and x2 be the hole diameter with mean 0.253in. and deviation 0.002 in.
a) y=x2-x1 denote the difference between hole and peg diameter
if y<0 , the peg won’t go inside the hole and
if y>0 ,the peg be loose to the hole
So using y the manufacture can find the required diameter of the hole.
b)Now, we have to find the mean of the random variable y
μ(y) = μ(x2) - μ(x1)
μ(y) = 0.253-0.25
μ(y) = 0.003
c) Now we have to find the standard deviation of the y
σ(y) = √{var(x1)+ var(x2)}(x1 and x2 are independent)
σ(y) = √0.000036+0.000004
σ(y) = √0.00004
σ(y) = 0.0063
d) It is reasonable to assume that x1 and x2 are independent since peg and hole are made of different wood.
e) With a standard deviation larger than the mean , it would be fairly likely to observe a negative value of y, so it would be a relatively common occurrence to find a peg that was too big to fit in the predrilled hole. We can see that mean of y is greater than standard deviation of y, So mostly the peg maybe bigger than hole.

How to determine the degree to walk?From the question, we have the following parameters that can be used in our computation:
Lengths = 989 paces, 673 paces and 861 paces
These paces can be represented as
x = 989
y = 673
z = 861
The measure of the required angle (angle Z) i.e. the degree to walk can be calculated using the following cosine rule
z² = x² + y² - 2xy * cos(Z)
Substitute the known values in the above equation, so, we have the following representation
861² = 989² + 673² - 2 * 989 * 673 * cos(Z)
Evaluate the exponents, the products and the summation
So, we have the following representation
741321 = 1431050 - 1331194 * cos(Z)
Evaluate the like terms
- 1331194 * cos(Z) = -689729

prisms, pyramids and spheres have 3 dimensions - length, width, and depth. three dimensional objects have vertices, edges, and faces unless they are the solids like cylinders, cones, and spheres.
A solid figure is a three-dimensional object. That is, it has length, width, and height. Because they are three-dimensional, they have depth and occupy space in our universe. Body types are identified according to characteristics specific to each body type. In particular, we can observe the number of faces, edges, vertices, and the shape of the base.
A flat face of a solid is its face or side, as it is commonly called. The base is the surface on which the figure rests. A solid edge is a line segment where two faces meet. A vertex is an angle formed where the endpoints of two or more face segments meet.
A sphere is a solid figure that has no faces, edges, or vertices. This is because it is perfectly round. No flat sides or corners.
A cone has faces but no edges or vertices. His face is circular. A circle is a plane because it is a flat planar shape. However, since it is rounded on the outside, it does not form edges or corners.
Cylinder that has two circular faces but no edges or corners:
A pyramid has a base and at least three triangular faces. There are edges where faces meet each other or meet the bottom, vertices where two faces meet the bottom, and top vertices where all the triangle faces meet. Pyramids are named for the shape of their base.
A triangular pyramid has a triangular base and his other three triangular faces, or four triangles in total.
A pyramid has a rectangular base and a pyramid has a square base. Both have four triangular faces, for a total of five faces.
Prism:
A prism is a solid with two congruent parallel faces and any number of sides. That is, it can have any number of faces, but at least two faces must be parallel. The shape of the two parallel faces can be triangles, squares, rectangles, pentagons, hexagons, or other types of polygons. Prisms are named after the shape of the base.
Sphere:
A sphere is a geometric object that is the three-dimensional analogue of the two-dimensional circle. A sphere is a set of points that are all the same distance r from a given point in 3D space. This given point is the center of the sphere and r is the radius of the sphere. Spheres are fundamental objects in many areas of mathematics. Spherical and near-spherical shapes also occur in nature and industry. Bubbles, like soap bubbles, are spherical in equilibrium. The Earth is often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy.

A set-to-set function f is a relation that assigns one element of the set A to each element of the other set B. The set A is the domain of the function (also called the set of inputs) and the set B contains the range (also called the set of outputs).
Let's denote f as exponential function with the base 'a':
f(x) = a ˣ
where, a > 0 and a ≠ 1 and x is any real number.
1. Not an exponential function:
We have the following equation:
[tex]y = 100 (1 - 12)^{t}[/tex]
We can write the equation as:
[tex]y = 100 (-11)^{t}[/tex]
Let's denote f as exponential function with the base 'a':
f(x) = a ˣ
where, a > 0 and a ≠ 1 and x is any real number.
Therefore: a must be more than 01.
In this problem, a = -11, therefore this is not an exponential function.
2. Growth.:
The function:
[tex]y= 0.1(1.25)^{t}[/tex]
The above equation is an exponential function because is a function of the form
[tex]f(t) = ka^t[/tex]
where, a > 0 and k is constant
Therefore, k = 0.1 and a = 1.25 . So, a is greater than 1.
3. Growth:
The function:
[tex]y = {(1 - 0.03)12}^2t[/tex]
The above equation can be written as:
[tex]y = 11.64^{2t}[/tex]
which is an exponential function because is a function of the form
[tex]f(t) = a^{bt}[/tex]
where, a > 0 and b is constant.
So, a = 11.64 and b = 4 . Since a is greater than 1.
4. Decay:
The function:
[tex]y = 426(0.98)^t[/tex]
This is an exponential function because is a function of the form
[tex]f(t) = ka^t[/tex]
where, a > 0 and k is constant
So, k = 426 and a = 0.98. Since, a is less than 1.
5. Growth:
The function:
[tex]y = 2050(12)^t[/tex]
This is an exponential function because is a function of the form
[tex]f(t) = ka^t[/tex]
where, a > 0 and k is constant.
So, k = 2050 and a = 12 . Since, a is greater than 01.

a line passes through the point (-6,3) and has a slope of 3/2
The equation of slope intercept form is y = 3/2x + 12 if a line passes through the point (-6,3) and has a slope of 3/2.
Define slope intercept form.The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation. The slope, m, is a measure of how steep a line is. The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.
Given
A line passes through the point (-6,3)
and has a slope of 3/2
Slope intercept form
y = mx + b
Equation,
y - 3 = 3/2(x - (-6))
y - 3 = 3/2(x+6)
2y - 6 = 3x + 18
2y = 3x + 24
y = 3/2x + 12

Multiple Choice
The sum of the four quarterly seasonal index numbers is 4.
The index for any quarter must be between 0 and 2.
The average index is 1.
An index of 0.75 for quarter-one sales indicates that sales were 25 percent lower than average sales.
An index of 1.10 indicates sales 10% above the norm.
The option b "The index for any quarter must be between 0 and 2" is correct.
In the given question, we have to find the incorrect statement about a company has computed a seasonal index for its quarterly sales.
For its quarterly sales, the corporation has created a seasonal indicator.
Consequently, it is correct that the four quarterly seasonal index figures add up to 4.
True, the average index is 1.
In this situation, an index of 0.75 for the first quarter's sales implies that they were 25% below average, while an index of 1.10 shows that they were 10% over average.
Hence, the incorrect statement of the option b "The index for any quarter must be between 0 and 2" is correct.
