Answer:

B .  She is incorrect because when substituting 2 for m the result was a false statement.

Step-by-step explanation:

Edge. 2020

Answer:

B

Step-by-step explanation:

(a)The optimal order quantity is  4609 units.

(b)The time between orders is  1.98 months.

To determine the optimal order quantity and the approximate time between orders, the Economic Order Quantity (EOQ) model. The EOQ model minimizes the total cost of inventory by balancing ordering costs and carrying costs.

Optimal Order Quantity:

The formula for the EOQ is given by:

EOQ = √[(2DS) / H]

Where:

D = Annual demand

S = Cost per order

H = Holding cost per unit per year

calculate the annual demand (D) using the 2020

sales numbers provided:

D = 651 + 808 + 514 + 174 + 435 + 426 + 687 + 582 + 662 + 1551 + 1295 + 1774

= 9559 units

To calculate the cost per order (S) and the holding cost per unit per year (H).

The cost per order (S) is given as $500.

The holding cost per unit per year (H)  calculated as follows:

H = Carrying cost percentage × Unit value

= 0.30 × $3

= $0.90

substitute these values into the EOQ formula:

EOQ = √[(2 × 9559 × $500) / $0.90]

= √[19118000 / $0.90]

≈ √21242222.22

≈ 4608.71

Approximate Time Between Orders:

To calculate the approximate time between orders, we'll divide the total number of working days in a year by the number of orders per year.

Assuming 360 days in a year and a lead time of 1 week (7 days) for shipping, we have:

Working days in a year = 360 - 7 = 353 days

Approximate time between orders = Working days in a year / Number of orders per year

= 353 / (9559 / 4609)

= 0.165 years

Converting this time to months:

Approximate time between orders (months) = 0.165 × 12

= 1.98 months

Step-by-step explanation:

The body masses of the two children in terms of their father's body mass, x, are:

First child's body mass = 5x/6 kg

Second child's body mass = 4x/5 kg

To express the body mass of the man's two children in terms of their father's body mass, we can use the given ratios.

Let the body mass of the man be x kg.

The first child's body mass is five-sixths of their father's body mass:

Body mass of the first child = (5/6) * x

= 5x/6 kg.

The second child's body mass is four-fifths of their father's body mass:

Body mass of the second child = (4/5) * x

= 4x/5 kg.

Therefore, the body masses of the two children in terms of their father's body mass, x, are:

First child's body mass = 5x/6 kg

Second child's body mass = 4x/5 kg

Based on the given data, we can calculate the control limits using 3-sigma for the diameter of the auto pistons.

a) The value of x is 155.56 mm (rounded to two decimal places).

b) The value of R is 4.44 mm (rounded to two decimal places).

c) Using 3-sigma, the Upper Control Limit (UCL) for the diameter is calculated as:

UCL = x + 3R = 155.56 + 34.44 = 156.93 mm (rounded to two decimal places)

The Lower Control Limit (LCL) for the diameter is calculated as:

LCL = x - 3R = 155.56 - 34.44 = 154.19 mm (rounded to two decimal places)

d) Using 3-sigma, the Upper Control Limit for the Range (UCLR) is calculated as:

UCLR = D4 * R = 2.115 * 4.44 = 7.89 mm (rounded to two decimal places)

The Lower Control Limit for the Range (LCLR) is always 0 in this case since negative ranges are not possible.

e) If the true diameter mean should be 155 mm, the new centerline (nominal line) would be 155 mm. In this case, the UCL and LCL would be calculated using 3-sigma as follows:

UCL = Nominal + 3R = 155 + 34.44 = 156.37 mm (rounded to two decimal places)

LCL = Nominal - 3R = 155 - 34.44 = 153.63 mm (rounded to two decimal places)

Please note that the control limits calculated using 3-sigma assume a normal distribution and the data follows the same pattern in the future.

The system of equations can be solved using the Gauss-Jordan method. After performing row operations on the augmented matrix, we find that the system has infinitely many solutions.

To solve the system of equations, we construct the augmented matrix by combining the coefficients and constants:

[-10 -15 -1 | 39]

[-6 -25 -2 | 8]

[8 15 1 | 86]

Using row operations, we aim to transform this matrix into reduced row-echelon form. After performing the necessary row operations, we obtain the following matrix:

[1 0 -1/5 | -7/5]

[0 1 1/5 | 3/5]

[0 0 0 | 0]

In this reduced row-echelon form, we see that the last row contains all zeroes. This indicates that the system of equations is dependent, meaning there are infinitely many solutions.

Therefore, the correct choice is B. This system has infinitely many solutions.

To test the claim that females are more likely to own a cat compared to males, a statistical analysis can be performed using a hypothesis test and data collection methods.

To investigate the claim that females are more likely to own a cat compared to males, we would start by collecting relevant data. A possible method could be conducting surveys or questionnaires to gather information on cat ownership and gender.

The survey would include questions asking respondents to indicate their gender and whether they own a cat or not.

Once the data is collected, it can be analyzed using statistical tests to determine if there is a significant difference between the cat ownership rates of females and males. One suitable test for this scenario could be the chi-square test for independence.

This test assesses the association between two categorical variables, such as gender and cat ownership, and determines if the observed differences are statistically significant.

To display the data, a contingency table can be created with the rows representing gender (male and female) and the columns representing cat ownership (yes and no). The observed frequencies can be filled in the respective cells, and the expected frequencies can be calculated based on the assumption of no association between gender and cat ownership.

The chi-square test can then be applied to determine if the observed differences deviate significantly from the expected values.

The report would include a clear statement of the claim being tested, a description of the data collection method, the contingency table displaying the observed and expected frequencies, the calculated chi-square test statistic, the degrees of freedom, and the p-value.

The conclusion would state whether the claim is supported or rejected based on the statistical analysis of the data.

We can substitute the values of x and y from each point into the inequality and check if the inequality is satisfied or not.

Let's check each point:

For points (12, 6):

\((y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (12+2)^2/24 \\= 49/6 - 196/3 \\= -57.33\)

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

For points (–2, 6):

\((y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (-2+2)^2/24 \\= 49/6\)

Here, the value of the expression is greater than or equal to 1, so this point does justify the shaded area.

For points (8, –6):

\((y+1)^2/6 -(x+2)^2/24 \\= (-6+1)^2/6 - (8+2)^2/24 \\= 25/6-100/24\)

Here, the value of the expression is greater than or equal to 1, so this point does not justify the shaded area.

For point (–1, –2):

\((y+1)^2/6 -(x+2)^2/24 \\= (-2+1)^2/6 - (-1+2)^2/24 \\= 1/6 - 1/24 \\= 1/8\)

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

Therefore, the points that justify the shaded area are (–2, 6).

In the congruent triangles both triangle are same . In this triangle 2.3.3 congruent triangle image given below to understand better.

According to the question, given that

2.3.3 congruent triangle under congruence triangle are explain:

Both triangles are said to be congruent if the three angles and three sides of one triangle match the corresponding angles and sides of the other triangle. We can see from the examples PQR and XYZ that PQ = XY, PR = XZ, and QR = YZ, and thus P = X, Q = Y, and R = Z. Then, we can state that XYZ and PQR.

To be congruent, the two triangles must be the same size and shape. It is necessary for both triangles to be superimposed on one another. A triangle appears to be in a different place or have a different look as we rotate, reflect, and/or translate it.

Two triangles must meet five requirements in order to be congruent. The congruence properties are SSS, SAS, ASA, AAS, and RHS.

SSS Congruence Criteria

Side-Side-Side criterion is referred to as the SSS criterion. According to this standard, two triangles are congruent if their respective triangles' three sides are equal to one another.

The three angles of BAC must be identical to the corresponding angles of XYZ if, according to the SSS condition, BAC XYZ.

SAS Congruence Criteria

Side-Angle-Side criterion is referred to as the SAS criterion. According to this standard, two triangles are said to be congruent if their matching sides and included angles are the same on each side of each other.

The third side (AB) and the other two angles of ABC must be identical to the equivalent side (XY) and the angles of XYZ if ABC XYZ under the SAS condition.

ASA Congruence Criteria

Angle-Side-Angle criterion is also known as ASA criterion. According to the ASA criterion, two triangles are congruent if any two of their included sides and related angles are equivalent in size to those of the other triangle.

AAS Congruence Criteria

Angle-Angle-Side criterion is also known as the AAS criterion. Two triangles are said to be congruent according to the AAS criterion if any two angles and the non-included side of one triangle match the corresponding angles and side of the second triangle.

RHS Congruence Criteria

Right angle-hypotenuse-side congruence is referred to as the RHS criterion. If the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, then two triangles are said to be congruent according to this criterion.

Answer:

See below for answers and explanations (along with attached graph)

Step-by-step explanation:

It best helps to convert the equation into vertex form because it provides a lot of information about the characteristics of the parabola:

\(f(x)=2x^2-8x+4\\\\f(x)=2(x^2-4x+2)\\\\f(x)+2(2)=2(x^2-4x+2+2)\\\\f(x)+4=2(x^2-4x+4)\\\\f(x)+4=2(x-2)^2\\\\f(x)=2(x-2)^2-4\)

Now, recall that vertex form is \(y=a(x-h)^2+k\) where \((h,k)\) is the vertex, the axis of symmetry is the line \(x=h\), and \(a\) is the growth or shrink factor.

Vertex

This is pretty simple as you can just look at the equation, so \((h,k)\rightarrow(2,-4)\)

Axis of Symmetry

Again, also simple, so \(x=2\) would be the line.

X-intercepts

The beauty of having converted the equation to vertex form is that when we set \(f(x)=0\), we can easily find our x-intercepts with minimal work:

\(f(x)=2(x-2)^2-4\\\\0=2(x-2)^2-4\\\\4=2(x-2)^2\\\\2=(x-2)^2\\\\\pm\sqrt{2}=x-2\\\\x=2\pm\sqrt{2}\)

So, our x-intercepts are at the points \((2+\sqrt{2},0)\) and \((2-\sqrt{2},0)\).

Y-intercept

This is just a simple substitution of \(x=0\) and everything works out nicely:

\(f(x)=2(x-2)^2-4\\\\f(0)=2(0-2)^2-4\\\\f(0)=2(-2)^2-4\\\\f(0)=2(4)-4\\\\f(0)=8-4\\\\f(0)=4\)

So, our y-intercept would be at the point \((0,4)\).

Domain

If you try any real number for \(x\), there will always be a value for \(f(x)\), so the domain of the function is \((-\infty,\infty)\) in interval notation.

Range

Recall back to when we found our vertex of \((2,-4)\). Because the leading coefficient of the function is positive, our vertex is the minimum, which means \(f(x)\) cannot be lower than -4, but anything higher works, so our range is \([-4,\infty)\) in interval notation.

End Behavior

We can easily see that if we plug in a large value for \(x\), then \(f(x)\) will also be a large value, so our end behavior for the function is that as \(x\rightarrow\infty\), then \(f(x)\rightarrow \infty\). Another good indicator of this end behavior is the even leading degree of 2.

To determine whether a relation is asymmetric, we can use the matrix representation of the relation on a set. Specifically, if a relation is asymmetric, then every entry above the main diagonal (i.e., where the row index is greater than the column index) must be 0.

This is because if (a,b) is in the relation, then (b,a) cannot be in the relation if it is asymmetric. Therefore, if the matrix representation of a relation has any non-zero entries above the main diagonal, then the relation is not asymmetric. If all entries above the main diagonal are 0, then the relation is asymmetric.
To determine whether a relation R on a set A is asymmetric using its matrix representation, follow these steps:

1. Create the matrix M representing the relation R, where M[i][j] = 1 if (a_i, a_j) is in R and M[i][j] = 0 otherwise.
2. Check the main diagonal of matrix M. If any element M[i][i] is equal to 1, the relation is not asymmetric.
3. For all other pairs (i, j), if M[i][j] = 1, ensure M[j][i] = 0. If you find any pair (i, j) where M[i][j] = M[j][i] = 1, the relation is not asymmetric.

If all these conditions hold, the relation R is asymmetric.
