the weights that separate the top 9%of the machine components is 6.33 ounces and the bottom 9% of the machine components is 6.27 ounces.

We know that the weights of the machine components are normally distributed with a mean of 6.3 ounces and a standard deviation of 0.03 ounces.

Let X be the weight of a machine component.

To find the weights that separate the top 9% and the bottom 9%, we need to find the z-scores corresponding to these percentiles and then use them to find the corresponding weights.

Using a standard normal distribution table, we can find that the z-score corresponding to the top 9% is approximately 1.34, and the z-score corresponding to the bottom 9% is approximately -1.34.

Using the formula for converting a value to a z-score:

z = (X - μ) / σ

For the top 9% weight, we have:

1.34 = (X - 6.3) / 0.03

Solving for X, we get:

X = 6.33 ounces

For the bottom 9% weight, we have:

-1.34 = (X - 6.3) / 0.03

Solving for X, we get:

X = 6.27 ounces

Therefore, the weights that separate the top 9% and the bottom 9% of the machine components are 6.33 ounces and 6.27 ounces, respectively. Any components with weights outside of this range may be considered for rejection.

The given quadratic function, y=x^2+7x+4, in vertex form is y = (x + 7/2)^2 - 33/4

From the question, we are  to write the given quadratic function in vertex form

To write the quadratic function y = x^2 + 7x + 4 in vertex form, we can complete the square. The vertex form of a quadratic function is y = a(x - h)^2 + k, where (h, k) is the vertex.

To complete the square, we need to add and subtract a constant inside the parentheses so that the expression inside the parentheses becomes a perfect square trinomial. We can do this by adding and subtracting (7/2)^2 = 49/4 inside the parentheses:

y = x^2 + 7x + 4

= (x^2 + 7x + 49/4) - 49/4 + 4 (adding and subtracting 49/4)

= (x + 7/2)^2 - 33/4

Hence, the vertex form is y = (x + 7/2)^2 - 33/4

Answer:

  14(y -7/2) = (x -5)²

Step-by-step explanation:

You want an equation for the parabola with focus (5, 7) and directrix y=0.

The vertex of a parabola is halfway between the focus and the directrix. When the directrix is a horizontal line, the y-coordinate of the vertex is the average of the y-coordinates of the focus and directrix. The x-coordinate of the vertex is the same as that of the focus.

The scale factor in the vertex form equation is 1/(4p), where p is the distance from the vertex to the directrix.

Here, the vertex y-coordinate is (7+0)/2 = 3.5. The vertex x-coordinate is 5. The distance from the vertex to the directrix is 3.5 -0 = 3.5.

Then the vertex form equation for the parabola can be written as ...

  y = a(x -h)² +k . . . . . . . . parabola with scale factor 'a' and vertex (h, k)

  y = 1/(4·3.5)·(x -5)² +3.5 . . . . . parabola with scale factor 1/(4·3.5) and vertex (5, 3.5)

The fraction can be eliminated to give the form ...

  14(y -3.5) = (x -5)²

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

To solve for r in the formula V = πr², we need to isolate r on one side of the equation.

We can do this by dividing both sides of the equation by π and then taking the square root of both sides:

If the combined weight is 1.5 kilograms and the weight of the gram weights is 0.5 kilograms, then the mass of the object is 1 kilogram.

Mass is describes the amount of matter it contains. It is usually measured in kilograms or pounds. Mass is distinct from weight, which measures the force of gravity on an object.

To measure the mass of an object that I think has a mass greater than 1 kilogram, I will use a pan balance and kilogram and gram weights.

First, I will set the pan balance to 0 by adjusting the counterweight.

Then, I will place the object on one of the pans and add weights to the other pan until the balance is equal.

I will first use 1 kilogram weights and then add smaller gram weights until the pan balance is equal.

Once the pan balance is equal, the combined weight of the object and the weights will be the mass of the object.

I can then calculate the mass in kilograms by subtracting the weight of the gram weights from the total mass.

Given that you are an elementary school teacher and you are evaluating the reading levels of your students. You find an individual that reads 50 word per minute. You do some research and determine that the reading rates for their grade level are normally distributed with a mean of 85 words per minutes and a standard deviation of 20 words per minutes.The percentile of a given value represents the percentage of the distribution that falls below that value.To find the percentile rank of the student's reading level, we can use the Z-score formula:$$z = \frac{X - \mu}{\sigma}$$where X is the student's reading rate, μ is the mean reading rate for the grade level, and σ is the standard deviation of the reading rates for the grade level. Substituting the given values, we get:$$z = \frac{50 - 85}{20} = -1.75$$The negative sign indicates that the student's reading rate is below the mean rate for the grade level. Now we need to find the percentile of the Z-score -1.75.Using a standard normal table or calculator, we can find that the area to the left of -1.75 under the standard normal distribution is 0.0401.

The correct option is (c) i.e. The segments are parallel.

What are parallel lines?

Parallel lines are two lines in a two-dimensional space that never intersect, no matter how far they are extended in either direction. They always maintain the same distance between them and have the same slope. The symbol for parallel lines is "||".

In geometry, parallel lines are important because they create angles that are congruent or equal to each other when intersected by a third line, known as a transversal. This concept is used in many practical applications, such as in construction, engineering, and navigation.

The segments are parallel.

If the slopes of two lines are equal, it means that the lines are either parallel or they are the same line. In this case, since the two segments have zero slope, it means that they are horizontal lines. Horizontal lines are always parallel to each other, so we can conclude that the two segments are parallel.

The expressions that are equivalent to 81x² + 180x - 200 = 100 are:  27x² - 60x + 100 = 0, x² + (20/9)x - (100/27) = 0, (x + 1/3)(x + 10/3) = 0, (3x + 1)(3x + 10) = 0.

To find the expressions that are equivalent to 81x² + 180x - 200 = 100, we can simplify and manipulate the equation using basic algebraic operations.

Starting with the given equation:

81x² + 180x - 200 = 100

We can subtract 100 from both sides to get:

81x² + 180x - 300 = 0

Now, we can simplify the left side by dividing each term by their greatest common factor, which is 3:

27x² + 60x - 100 = 0

Next, we can divide each term by 27 to make the coefficient of x² equal to 1:

x² + (60/27)x - (100/27) = 0

Simplifying the fractions, we get:

x² + (20/9)x - (100/27) = 0

Now, we can use the quadratic formula to find the solutions of this equation:

x = (-b ± √(b² - 4ac))/2a

where a = 1, b = 20/9, and c = -100/27.

Plugging in these values, we get:

x = (-20/9 ± √((20/9)² + 4(1)(100/27)))/2(1)

x = (-20/9 ± √(400/81 + 400/27))/2

x = (-20/9 ± √(1600/81))/2

Answer:

A. Corresponding angles

B. Vertically opposite angles

C. Alternate angles

Step-by-step explanation:

Alternate angles are two angles, not adjoining one another, that are formed on opposite sides of a line that intersects two other lines. If the original two lines are parallel, the alternate angles are equal.

Vertically Opposite Angles are the angles opposite each other when two lines cross "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down. Example: a° and b° are vertically opposite angles.

Corresponding angles are the angles which occupy the same relative position at each intersection where a straight-line crosses two others. If the two lines are parallel, the corresponding angles are equal.

A matrix is a rectangular array of numbers, arranged in rows and columns. Matrices are used in many areas of mathematics, science, and engineering to represent and manipulate data.

Matrices can have any number of rows and columns, but are typically denoted by the letter A with a subscript indicating the number of rows and columns. For example, a matrix with 2 rows and 3 columns might be denoted as [tex]A_{2x3}[/tex].

To find -2A, we need to multiply every element of matrix A by -2. In other words, we need to apply the scalar multiplication operation to every element in the matrix.

Scalar multiplication is a simple operation where we multiply each element in a matrix by a scalar, which is just a regular number. In this case, our scalar is -2.

To perform scalar multiplication on a matrix, we simply multiply each element of the matrix by the scalar. So, for each element in matrix A, we can write:

(-2) * aij

where i is the row number and j is the column number of the element.

We can use this formula to find each element of -2A. Let's look at the first element, a11:

(-2) * a11 = (-2) * 5 = -10

So the first element of -2A is -10. We can repeat this process for each element in the matrix to get the following result:

            6   -10   0

-2A  =  -6    4   -2

            2   -8   -14

The normal distribution is a mathematical model used to describe real-world data that occurs in many scenarios, including restaurant wait times. The normal distribution is characterized by a mean and a standard deviation; in this case, the mean wait time is 20 minutes, and the standard deviation is 4 minutes.

In order to find the maximum wait time for customers so that at most 1% of them would receive their meals for free, we can use the normal distribution graph.

The graph shows the probability of a customer waiting any given amount of time. The mean is the highest point on the graph, while the standard deviation can be seen as two "bumps" on either side of the mean. For this scenario, any customer who waits more than 25.5 minutes will be in the top 1% of wait times, and therefore, should receive their meal for free.

This provides a reasonable time limit for customers to expect their meal, while also helping to dispel any negative perceptions about the speed of service.

In terms of the company's profitability, offering free meals to the top 1% of customers does not present any significant risk. The 25.5 minute wait time is well above the average wait time of 20 minutes, so it's unlikely that the company will incur a significant loss due to this promotion.

To sum up, the maximum wait time to be advertised to customers so that 1% of them will receive their meals for free is 25.5 minutes. The normal distribution graph shows how this wait time is chosen, as it corresponds to the top 1% of wait times.

As the average wait time is much lower than this maximum wait time, this promotion is unlikely to cause the company any significant loss in profit.

The extreme value of the function f(x) is the minimum value of the profit, which occurs when x = 15.

The given function f(x) represents the profit in thousands of dollars of selling x items. To find the meaning of the extreme value, we need to find the critical points of the function, which are the values of x where the derivative of the function is equal to zero or undefined.

The derivative of the given function is:

f'(x) = 12x - 180

Setting f'(x) = 0 to find critical points:

12x - 180 = 0

Solving for x, we get:

x = 15

So, x = 15 is the critical point of the function.

Now, we need to determine whether this critical point is a maximum or a minimum.

To do so, we can use the second derivative test. The second derivative of the given function is:

f''(x) = 12

Since f''(15) = 12 > 0, the critical point x = 15 is a minimum.

Therefore, the extreme value of the function f(x) is the minimum value of the profit, which occurs when x = 15. This minimum value represents the least amount of profit that can be earned by selling the items.
