Answer:

The measure of the angle labeled d

Step-by-step explanation:

I took the quick check for "angle angle side postulate"

Given:

[tex]y=\log_{\sqrt{x}}x[/tex]

To find:

The value of [tex]\dfrac{dy}{dx}[/tex].

Solution:

We have,

[tex]y=\log_{\sqrt{x}}x[/tex]

It can be written as

[tex]y=\log_{\sqrt{x}}(\sqrt{x})^2[/tex]

Using property of log, we get

[tex]y=2[/tex]          [tex][\because \log_aa^x=x][/tex]

Now, differentiate both sides with respect to x.

[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(2)[/tex]

[tex]\dfrac{dy}{dx}=0[/tex]          [tex][\because \dfrac{d}{dx}(Constant)=0][/tex]

Therefore, the value of [tex]\dfrac{dy}{dx}[/tex] is 0.

Answer:

We conclude that the average number of pages that Sarah reads per hour will be: 10.75 page per hour

Step-by-step explanation:

Given

The average number of pages per hour can be calculated by simply dividing the total number of pages i.e. 64.5 pages by the number of hours spent on reading i.e. 6 hours.

Thus,

Average number of pages per hour = 64.5 pages / 6 hours

                                                            = 10.75 page per hour

Therefore, we conclude that the average number of pages that Sarah reads per hour will be: 10.75 page per hour

Answer:

the weekly sales are $8,800 to earn the similar amount with the two options

Step-by-step explanation:

The computation is shown below:

The earnings in option A is

= 40 hours × $22

= $880

Now let us assume the weekly sales be x

So the equation would be

10%x = $880

0.10x = $880

x = $8,800

Hence, the weekly sales are $8,800 to earn a similar amount with the two options

Complete Question

Leicester City Fanstore (LCF) will be selling the "new season jersey" for the 2018-2019 season. The regular price of the jersey is $80. Each jersey costs $40. Leftover jerseys will be sold at the end of the season (or later) at $30. Since jerseys are produced in China and lead time is long, Puma wants LCF to decide the quantity right now (December 2017).

a. After some analysis using historic data, LCF expects that the demand will follow a Normal distribution with a mean 40,000 and a standard deviation of 8,000 due to uncertainty in team performance. How many jerseys should LCF order?

b. If a customer cannot buy the jersey from LCF (in the case of a stock-out), they may leave the store disappointed and use other channels (such as Puma stores or puma.com) in future. LCF thinks that the lost customer goodwill is around $10. Should LCF change their decision in part (a)? If yes, please state the number of jerseys LCF should order.

c. Please state whether the following statement is always true, and give a brief explanation. If [tex]C_o =C_i[/tex], the news vendor solution is the mean.

Answer:

a

   [tex]N = 46728[/tex]

b

  [tex]n = 47728[/tex]

c

  Yes it is always true  

Step-by-step explanation:

From the question we are told that

   The regular price of the jersey is  [tex]P_r = \$ 80[/tex]

    The cost of producing a jersey is [tex]C= \$ 40[/tex]

  The left-over price of the jersey is [tex]P_o = $ 30[/tex]

   The mean is  [tex]\mu = 40000[/tex]

   The standard deviation is [tex]\sigma = 8000[/tex]

   The cost of lost customer goodwill is [tex]C_g = \$ 10[/tex]

Generally the fund that LCF will loss for one jersey if they order for too many  jersey (i.e more than they need )is mathematically represented  

           [tex]C_o = P_o - C[/tex]

=>        [tex]C_o = 40 - 30[/tex]

=>        [tex]C_o = \$ 10[/tex]

Generally the fund that LCF will loss for one jersey if they order lesser amount  jersey (i.e less than they need )is mathematically represented  

           [tex]C_i = P_r - C[/tex]

=>        [tex]C_i = 80 - 40[/tex]

=>        [tex]C_i = \$ 40[/tex]

Generally the critical ratio is mathematically represented as

             [tex]Z = \frac{C_i }{ C_i + C_o}[/tex]

=>           [tex]Z = \frac{40}{ 40 + 10}[/tex]

=>           [tex]Z = 0.8[/tex]

Generally the critical value of  [tex]Z = 0.8[/tex] to the right of the normal curve is

         [tex]z = 0.841[/tex]

Generally the optimal quantity of jersey to order is mathematically represented as

             [tex]N = \mu * [z * \sigma][/tex]

=>          [tex]N = 40000 * [0.841 * 8000][/tex]

=>          [tex]N = 46728[/tex]

Considering question b

  Generally considering the factor of customer goodwill  the fund that LCF will loss for one jersey if they order lesser amount  jersey (i.e less than they need )is mathematically represented  as

           [tex]C_k = C_i + C_g[/tex]

=>        [tex]C_k = 40 + 10[/tex]

=>        [tex]C_k = \$ 50[/tex]

Now   the critical ratio is mathematically represented as

             [tex]Z = \frac{C_k }{ C_k + C_o}[/tex]

=>           [tex]Z = \frac{50}{ 50 + 10}[/tex]

=>           [tex]Z = 0.833[/tex]

Generally the critical value of  [tex]Z = 0.833[/tex] to the right of the normal curve is

         [tex]z = 0.966[/tex]

Generally the optimal quantity of jersey to order is mathematically represented as

             [tex]n = \mu * [z * \sigma][/tex]

=>          [tex]n = 40000 * [0.966 * 8000][/tex]

=>          [tex]n = 47728[/tex]

Considering question c

    When [tex]C_o =C_i[/tex] then

The critical ratio is mathematically represented as

             [tex]Z = \frac{C_k }{ C_k + C_k}[/tex]

=>           [tex]Z = \frac{1}{ 2}[/tex]

=>           [tex]Z = 0.5[/tex]          

Generally the critical value of  [tex]Z = 0.5[/tex] to the right of the normal curve is

         [tex]z = 0[/tex]

So

The optimal quantity of jersey to order is mathematically represented as

             [tex]n = \mu * [z * \sigma][/tex]

=>          [tex]n = 40000 * [0* 8000][/tex]

=>          [tex]n = 40000 = \mu[/tex]

Hence the statement in c is true

Answer:

Proof below

Step-by-step explanation:

To prove DE and AB are parallel, we compare the slopes of both segments

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Segment AB goes through the points (0,0) and (x2,0), thus:

[tex]\displaystyle m_{AB}=\frac{0-0}{x_2-0}=0[/tex]

The slope is 0 because the line is horizontal.

Now for the segment DE, the endpoints are

[tex]\displaystyle (\frac{x_1}{2},\frac{y_1}{2}),\ (\frac{x_1+x_2}{2},\frac{y_1}{2})[/tex]

The slope is:

[tex]\displaystyle m_{DE}=\frac{\frac{y_1}{2}-\frac{y_1}{2}}{\frac{x_1+x_2}{2}-\frac{x_1}{2}}[/tex]

[tex]\displaystyle m_{DE}=\frac{0}{\frac{x_2}{2}}=0[/tex]

Segment DE is also horizontal, thus is parallel to segment AB.

Answer:

48in sq

Step-by-step explanation:

8*12/2=8*6=48

Answer:

48in

Step-by-step explanation:

A triangle like this is like half of a rectangle. The rest fits in the upper left and right. So to find the area of the triangle, we're going to start be pretending it's a recrangle.

Our rectangle is 12 by 8.

12 x 8 = 96

If this were a rectangle, the area would be 96in.

Since it's a triangle and that's only half of a rectangle, the area is half of that.

96 / 2 = 48

The area of this triangle is 48in.

Answer: 17873.75 dollars

Step-by-step explanation:

We can use the equation: l = p x r x t (Total Interest = principal x interest rate x years/time)

9050 will be the principal; it's the amount you deposit in the first place.

7.5% is the interest rate. You can convert it to 0.075 as a decimal.

13 is the years/time. If Marcus's parents put the college fund in when he was 5 and now he's 18, there has been 13 years in between.

9050 x 0.075 x 13 = 8823.75

8823.75 + 9050 = $17873.75

So in Conclusion, the total amount in the account when Marcus is 18 is 17873.75 dollars.

Answer:

WY = 30

XZ = 10.5

Step-by-step explanation:

Paralellogram's diagonal's bisect eachother

Therefore,

[tex]n + 7 = 3 n[/tex]

Move the n over,

2n = 7

Divide both sides by 2,

n = 3.5

WY = 2(ZY) because definition of bisector

Simplify...

WY = 2(4n+1)

WY = 2(4(3.5)+1)

WY = 2(15)

WY = 30

You asked for XY, but the question asks for XZ, so I'm going to give XZ.

With n = 3.5 from above,

XZ = 3n

XZ = 3(3.5)

XZ = 10.5

The measure of XY and WY are; WY = 30 and XZ = 10.5

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Since Paralellogram's diagonal's bisect each other

Therefore,

2n = 7

Divide both sides by 2;

n = 3.5

WY = 2(ZY)

because definition of bisector

Simplify;

WY = 2(4n+1)

WY = 2(4(3.5)+1)

WY = 2(15)

WY = 30

we asked for XY,

With n = 3.5 from above,

XZ = 3n

XZ = 3(3.5)

XZ = 10.5

The measure of XY and WY are; WY = 30 and XZ = 10.5

it Permutation 32760

Step-by-step explanation:

it permutation because the order is matter

15p4=32760

This is the case of a combination and the possibility of arrangement is 1365.

The combination is the process of choosing items or things from a bigger group where the order is irrelevant. The combination formula aids in determining the number of possible combinations that can be created by selecting a portion of a bigger set of objects.

Given There are 15 applicants for four jobs: Computer Programmer, Software Tester, Manager, and Systems Engineer.

From the difference between permutation and combination:

A permutation is a method of arranging all the members in order. The combination is a selection of elements from a collection.

Since the order is not asked thus this is the case of a combination

and total arranging possibility = ⁿCₓ

total arranging possibility = ¹⁵C₄

total arranging possibility = 15! /( 11! * 41)

total arranging possibility = 1365

therefore, This is a combination case, and the number of possible arrangements is 1365.
