The proportion of company breadth between the widget's weight of [tex]0.13[/tex]and its weight of [tex]71[/tex]ounce is [tex]81.53[/tex].
What does the term "company" mean?Meaning of the word "company" A company is a collective of individuals. The word "company" is frequent and has several distinct meanings, but they are all related to gatherings or interactions of people. The most frequent usage of the term "company" is to describe a firm.
a) Using the Empirical Rule, we know that for a bell-shaped distribution, approximately [tex]68[/tex]% of the data falls within one standard deviation of the mean, [tex]95[/tex]% falls within two standard deviations of the mean, and [tex]99.7[/tex]% falls within three standard deviations of the mean. Therefore, for this problem, we can say:
[tex]95[/tex]% of the widget weights lie between [tex](59-2(6)) = 47[/tex] and [tex](59+2(6)) = 71[/tex] ounces.
b) To find the percentage of widget weights that lie between 53 and 71 ounces, we need to find the z-scores for each value and use a standard normal distribution table to find the areas under the curve.
The z-score for [tex]53[/tex] ounces is: [tex](53-59)/6 = -1.00[/tex]
The z-score for [tex]71[/tex] ounces is: [tex](71-59)/6 = 2.00[/tex]
Using a standard normal distribution table, we can find the area to the left of each z-score:
The area to the left of [tex]z = -1.00[/tex] is 0.1587
The area to the left of [tex]z = 2.00[/tex] is 0.9772
To find the percentage of widget weights between [tex]53[/tex] and [tex]71[/tex] ounces, we can subtract the area to the left of [tex]z = -1.00[/tex] from the area to the left of [tex]z = 2.00[/tex] and multiply by [tex]100[/tex]:
Percentage [tex]= (0.9772 - 0.1587) * 100 = 81.85[/tex]%
Therefore, approximately [tex]81.85[/tex]% of the widget weights lie between 53 and [tex]71[/tex] ounces.
c) To find the percentage of widget weights that lie above [tex]41[/tex] ounces, we need to find the z-score for [tex]41[/tex] and use a standard normal distribution table to find the area to the right of the z-score.
The z-score for 41 ounces is: [tex](41-59)/6 = -3.00[/tex]
Using a standard normal distribution table, we can find the area to the right of [tex]z = -3.00[/tex]:
The area to the right of [tex]z = -3.00[/tex] is [tex]0.0013[/tex]
To find the percentage of widget weights above [tex]41[/tex]ounces, we can multiply the area to the right of [tex]z = -3.00[/tex] by [tex]100[/tex]:
Percentage [tex]= 0.0013 * 100 = 0.13[/tex]%
Therefore, approximately [tex]0.13[/tex] % of the widget weights lie above [tex]41[/tex]ounces.

Between the widget's weight of 0.13 and its weight in ounces, there is an 68 % company breadth.
What do you mean by the term percentage?Percentage is a way of expressing a quantity or value as a fraction of 100. It is denoted by the symbol %, which means "per cent" or "out of 100"
a) Using the Empirical Rule, we know that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% of the data falls within two standard deviations of mean, and approximately 99.7% of the data falls within three standard deviations of mean.
Since the mean weight of the widgets is 59 ounces and the standard deviation is 6 ounces, we can use the Empirical Rule to determine that:
Approximately 68% of the widget weights lie between 53 and 65 ounces (one standard deviation below and above the mean).
Approximately 95% of widget weights lie between 47 and 71 ounces.
Approximately 99.7% of widget weights lie between 41 and 77 ounces.
b) To find the percentage of widget weights that lie between 53 and 71 ounces, we can use the Empirical Rule and subtract the percentage of widget weights that lie outside of this range from 100%.
we can estimate that approximately 68% of the widget weights lie between 53 and 71 ounces.
Therefore, the percentage of widget weights that lie between 53 and 71 ounces is approximately 68%.
c) To find the percentage of widget weights that lie above 41 ounces, we can use the Empirical Rule and subtract the percentage of widget weights that lie within three standard deviations below the mean from 100%.
Therefore, the percentage of widget weights that lie above 41 ounces is approximately:
100% - 99.7% = 0.3%
So, approximately 0.3% of the widget weights lie above 41 ounces.

Sumi owns a plant store she wants to put 438 plants in 7 equal rows How many plants will be left over after putting them in do
There will be 4 plants left over after putting them in 7 equal rows.
Calculating the number of left over plantsTo find out how many plants will be left over after putting them in 7 equal rows, we need to divide the total number of plants (438) by the number of rows (7) and then find the remainder.
We can use integer division to find out how many plants will be in each row:
438 ÷ 7 = 62
So each row will have 62 plants.
To find out how many plants will be left over, we can subtract the total number of plants from the product of the number of rows and the number of plants in each row:
438 - (7 x 62) = 438 - 434 = 4
Therefore, the number of plants remaining is 4 plants

How does f(x)=x change over the interval from x=2 to x=9?
Answer:
The function f(x) = x represents a straight line with a slope of 1, passing through the origin (0,0).
If we consider the interval from x = 2 to x = 9, we can see that the line starts at f(2) = 2 and ends at f(9) = 9.
Therefore, over the interval from x=2 to x=9, the function f(x) = x increases in a straight line fashion from 2 to 9.
In other words, the slope of the line is positive, and the function is monotonically increasing on this interval.

Solve the right triangle. Round your answers to the nearest tenth.
m∠A = _____ degrees
m∠B = _____ degrees
AB = ____ units
(40 points)
Answer:
m∠A = 50°
m∠B = 40°
AB = 15.5 units
Step-by-step explanation:
This is a right trangle, so we can use the Pythagorean Theorem to calculate AB.
AC² + BC² = AB²
AB² = 11.9² + 10²
AB² = 141.61 + 100
AB = √241.61
AB ≈ 15.5 units
Since this is a right triangle, we only need the angle measurement of either m∠A or m∠B to calculate the angle measurement of the other.
I will use sine function to calculate the angle measurements of A and B. Try to use a more precise value for AB than the rounded answer so our angle measurement will be closer to the actual angle.
sin(m∠B) = 10/15.54381
m∠B = sin⁻¹(10/15.54381)
m∠B = 40.04°
Round to nearest tenth, so m∠B = 40°
m∠A + m∠B + 90° = 180°
m∠A + 130° = 180°
m∠A = 50°

we should invest $479.17 each month to accumulate $81,000 in 12 years with an APR of 4 percent.
what is percent?
Percent is a way of expressing a number as a fraction of 100. The word "percent" comes from the Latin phrase "per centum," which means "by the hundred."
In the given question,
To calculate the monthly deposit needed to accumulate $81,000 in 12 years with an APR of 4%, we can use the formula for future value of an annuity:
FV = PMT x [(1 + r)ⁿ - 1] / r
Where:
FV = Future value of the investment (in this case, $81,000)
PMT = Monthly deposit
r = APR / 12 (monthly interest rate)
n = Number of months (12 years x 12 months per year = 144 months)
Substituting the given values, we get:
$81,000 = PMT x [(1 + 0.04/12)¹⁴⁴ - 1] / (0.04/12)
Simplifying this equation, we get:
PMT = $81,000 x (0.04/12) / [(1 + 0.04/12)¹⁴⁴ - 1]
PMT = $479.17
Therefore, you should invest $479.17 each month to accumulate $81,000 in 12 years with an APR of 4%.

The solutions to the original equation are x = 2nπ, where n is an integer.
What is trigonometric identity?A trigonometric identity is an equation that is true for all values of the variables within the domain of the functions involved.
According to question:We can use the trigonometric identity cos(2x) = cos²(x) - sin²(x) to simplify the left-hand side of the equation:
cos(2x)cos(x) - sin(2x)sin(x) = (cos²(x) - sin²(x))cos(x) - 2sin(x)cos(x)sin(x)
Simplifying further using the identity sin(2x) = 2sin(x)cos(x), we get:
(cos²(x) - 3sin²(x)cos(x)) + sin(2x) = 1
Substituting sin(2x) = 2sin(x)cos(x), we get:
cos³(x) - 3sin²(x)cos(x) + 2sin(x)cos(x) - 1 = 0
We can factor this expression as follows:
(cos²(x) - 1)(cos(x) - 2sin(x) + 1) = 0
The first factor has solutions cos(x) = ±1, which means x is an integer multiple of π/2. However, these solutions do not satisfy the original equation, since the left-hand side is always equal to zero.
The second factor gives us the equation cos(x) - 2sin(x) + 1 = 0. We can rewrite this as:
cos(x) + 1 = 2sin(x)
Using the identity sin²(x) + cos²(x) = 1, we can square both sides of this equation to get:
1 + 2cos(x) + cos²(x) = 4sin²(x)
Substituting sin²(x) = 1 - cos²(x), we get:
5cos²(x) - 4cos(x) - 3 = 0
This quadratic equation can be factored as:
(5cos(x) + 3)(cos(x) - 1) = 0
The first factor gives us the solution cos(x) = -3/5, but this is not a valid solution since the cosine function only takes values between -1 and 1.
The second factor gives us the solution cos(x) = 1, which means x is an integer multiple of 2π.
Therefore, the solutions to the original equation are:
x = 2nπ, where n is an integer.

What is the area of a right triangle with a height of seven and three fourths yards and a base of 20 yards?
140 yds2
155 yds2
thirty eight and three fourths yds2
seventy seven and one half y
Answer: If the height of seven and three fourths yards and a base of 20 yards, then the area of the right triangle is 77.5 square yards.
To calculate the area of a right triangle, we can use the formula:
Area = (base * height) / 2
where the base is one of the sides of the triangle, and the height is the perpendicular distance from that side to the opposite vertex.
In this case, the height of the right triangle is 7 and 3/4 yards, and the base is 20 yards. Plugging these values into the formula, we get:
Area = (20 * 7.75) / 2 = 155 / 2 = 77.5 square yards
In summary, to calculate the area of a right triangle, we can use the formula that relates the base and height to the area. In this case, we needed to use the given values of the height and base of the right triangle to compute the area in square yards.
The resulting area represents the amount of surface inside the triangle and is useful in many applications, such as geometry, physics, and engineering.

With the given values of circle, the value of x=3 and VS = 5.
What is circle?
A circle is a geometrical shape consisting of all the points in a plane that are equidistant from a given point called the center of the circle.
Since VZ = UZ, then Z is on the perpendicular bisector of QR and ST. This means that Z divides QR and ST into two equal parts.
Using the midpoint formula, we can find the midpoint of QR and ST:
Midpoint of QR = ( (1/2)*(4x-2) , 0 ) = (2x-1, 0)
Midpoint of ST = ( (1/2)*10 , 8 ) = (5, 8)
Since Z is the midpoint of QR and ST, we can set up two equations:
2x-1 = 5
0 = 8
The second equation is not possible, so we ignore it. Solving the first equation gives us:
2x-1 = 5
2x = 6
x = 3
Now that we know x, we can find the length of VS:
VS = ST - TV = ST- (ST/2) = 10 - (5) = 5
Therefore, x = 3 and VS = 5.

____ hours at 12 mph
____ hours at 10 mph
Thus, the time taken by Colby to travel at each speed is-
5 hours at 12 mph and 6 hours at 10 mph.
Define about the relation of speed and time:In the study of physics, the three key variables are speed, distance, and time. How quickly or slowly an object moves through one point to another is determined by the concept of speed. The distance travelled in a unit of time is referred to as speed. Distance is exactly proportional to velocity and speed, while time is constant.
The formula for speed:
speed = distance/time
Then ,
time = distance / speed
Let speed S1 = 12 mph , for this time taken t1.
Let the speed S2 = 10 mph , for this time taken t2.
Since, in each distance is same say 'd'.
Total time t = 11 hours.
t = t1 + t2
t = d/s1 + d/s2
11 = d(1/12 + 1/10)
11 = d(12+10) / (12*10)
d = 11*120 / 22

Answer: To write 93,000,000 in scientific notation, we need to move the decimal point to the left so that there is one non-zero digit to the left of the decimal point.
Counting the number of places we move the decimal point, we get:
93,000,000 = 9.3 x 10^7
Therefore, 93 million miles can be written in scientific notation as 9.3 x 10^7 miles.

What is the parameter for identifying different graph?In mathematics, a graph's points are frequently plotted on a coordinate surface. Each spot on the plane has an x- and y-coordinate that describes where it is. Knowing a point's coordinates is necessary in order to map it. (x, y).
Drawing the x-axis and y-axis, where x is the horizontal line and y is the vertical line, will allow us to display the points [tex]A(1, 2), B(-8, 5), and C(-2, 1)[/tex] on the coordinate axes.
Then, beginning at the origin [tex](0,0)[/tex] we can find point A by moving 2 units down on the y-axis and 1 unit to the right on the x-axis.
Starting at the beginning, move 8 units to the left on the x-axis and 5 units down on the y-axis to find Point B.
Starting at the beginning, move 2 units left on the x-axis and 1 unit up on the y-axis to find Point C.
Point B would be moved by the vector (2,8) to point C, giving the coordinates of point D as [tex](2,16).[/tex]
plot the coordinate axes below with the coordinates [tex]A(1,-2), B(-8,-5)[/tex], and C(-2,1). in order for points A, B, C, and D to make a parallelogram, specify the coordinates of point D.
Therefore, a parallelogram would be formed by the coordinates A [tex](3, -2), B (-3, 8), C (-5, -1),[/tex] and [tex]D (2, 16)[/tex] .

Due to an economic downturn, a company had to decrease its staff from 61 employees to 9 employees what was the percent decrease in staff? Round to answer to the nearest 10th.
(Photo added, please help I'm not smart)
Answer:
To calculate the percent decrease in staff, we need to find the difference between the original number of employees and the new number of employees, and then divide that difference by the original number of employees. Finally, we can multiply the result by 100 to get the percent decrease.
The difference between the original number of employees (61) and the new number of employees (9) is:
61 - 9 = 52
Dividing 52 by the original number of employees (61) gives:
52/61 ≈ 0.8525
Multiplying 0.8525 by 100 gives:
0.8525 × 100 ≈ 85.25
Therefore, the percent decrease in staff is approximately 85.25%. Rounded to the nearest tenth, the answer is 85.3%.
Answer:
= 85.3%
Step-by-step explanation:
Find how many employees are left:
61 - 9 = 52
Divide 52 by 61
= 0.8524590...
Multiple it by 100 to find %
= 85.245
Round to nearest tenth
= 85.3%

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
Answer:
Step-by-step explanation:
A circle with a diameter of 12 units and a center that lies on the y-axis would have an equation of the form:
(x - h)^2 + y^2 = r^2
where (h, 0) is the center of the circle, and r is the radius. We know that the diameter is 12 units, so the radius is half of that, which is 6 units.
Now we can check which of the given equations match this form:
x^2 + (y – 3)^2 = 36 : This is not in the required form, since the center is at (0, 3) and not on the y-axis.
x^2 + (y – 5)^2 = 6 : This is not in the required form, and also has a very small radius of sqrt(6), so it cannot have a diameter of 12 units.
(x – 4)² + y² = 36 : This is in the required form, with center at (4, 0), so it is a possible solution.
(x + 6)² + y² = 144 : This is in the required form, with center at (-6, 0), so it is also a possible solution.
x^2 + (y + 8)^2 = 36 : This is not in the required form, since the center is at (0, -8) and not on the y-axis.
Therefore, the two equations that represent circles with a diameter of 12 units and a center on the y-axis are:
(x – 4)² + y² = 36
(x + 6)² + y² = 144
Margot gave 12% of x number of dollars that she earned over the summer to an animal rescue shelter.
12% of x is about $60.00. Select all the statements that are true.
Thus, the total earning of Margot during summer is found to be $500.
Explain about the percentage of number:Although the usage of percent and percentage differs slightly, they both signify the same thing. It is customary to use percent or the symbol (%) along with a numerical value.
Although the percentage word was not very ancient, the technique was often used. The Ancient Romans used to calculate fractions as multiples of 1/100 in the absence of the decimal system.
Given :
Let the total earning of Margot be 'x'.Donated amount to animal rescue shelter. = $60Percentage - 12%So,
12% of x = 60.00
x = 60.0 * 100 / 12

Option B : The volume of the sphere with a diameter of 10 inches is approximately 523.6 cubic inches, and the closest answer choice is (B) 1150 cubic inches.
In the given diagram, we can see that the diameter of the sphere is 10 inches.
The volume of a sphere is given by the formula:
V = (4/3) * π * [tex]r^3[/tex]
where r is the radius of the sphere.
We know that the diameter of the sphere is 10 inches, so the radius is half of that, which is 5 inches.
Substituting the given values, we get:
V = (4/3) * π * [tex]5^3[/tex]
V = (4/3) * π * 125
V = 523.6 [tex]in^3[/tex] (rounded to one decimal place)
So, the closest answer choice to the volume of the sphere is (B) 1150 [tex]in^3[/tex].

The shape of the cross - section can be described as being a rectangle.
The perimeter of the cross section can be found to be 28.98 inches.
The area of the cross - section is therefore 50.94 square inches.
How to find the area and perimeter of the cross - section ?Since the plane intersects the cube through four of its vertices and opposite edges, the shape of the cross-section is a rectangle.
To find the length of the diagonal of the cube's face, we can use the Pythagorean theorem for a right triangle with sides of 6 inches:
d^2 = 6^2 + 6^2
d^2 = 36 + 36
d^2 = 72
d = √72 = 8.49 inches
To find the perimeter of the cross-section, we use the formula for the perimeter of a rectangle:
P = 2(length + width) = 2(6 + 8.49) = 2(14.49) = 28.98 inches
To find the area of the cross-section, we use the formula for the area of a rectangle:
A = length × width = 6 × 8.49 = 50.94 square inches

A 30-foot beam leans against the wall. The beam reaches the wall 16 feet above the ground. What is the measure of the angle formed by the beam and the ground?
(HINT: DRAW THE PICTURE)
The measure of the angle is degrees
(60 points)
the measure of the angle formed by the beam and the ground is approximately 57.76 degrees. the measure of the angle formed by the beam and the ground is approximately [tex]57.76^\circ[/tex] degrees.
What is Right triangles?
A right triangle is a type of triangle that has one angle measuring 90 degrees (a right angle). The side opposite to the right angle is called the hypotenuse, and the other two sides are called the legs.
The Pythagorean theorem is a fundamental concept in mathematics that relates to right triangles, stating that the square of the length of the hypotenuse is equal to the sum of the squares of lengths of two legs.
To solve this problem, we can use trigonometry and the properties of right triangles.
First, let's draw the picture:
In this diagram, we have a right triangle formed by the beam, the wall, and the ground. The height of the triangle is given as 16 feet, and the length of the hypotenuse (the beam) is 30 feet.
We need to find the length of the base of the triangle (the distance between the wall and the bottom of the beam), which we can call d.
Using the Pythagorean theorem, we can find the length of the opposite side of the triangle:
length = √(beam² - wall²)
length = √(30² - 16²)
length = √(900 - 256)
length = √644
length ≈ 25.37 feet
Now we can use the tangent function to find the angle θ:
tan(θ) = opposite/adjacent
tan(θ) = ground/wall
tan(θ) = 25.37/16
tan(θ) ≈ 1.586
To find θ, we need to take the inverse tangent (or arctangent) of 1.586:
[tex]\Theta = tan-1(1.586)[/tex]
[tex]\Theta \approx 57.76^\circ[/tex] degrees
Therefore, the measure of the angle formed by the beam and the ground is approximately [tex]57.76^\circ[/tex] degrees.
