Suppose that we want to increase production of consumer goods to a total of 6 units. Is it also possible to continue producing 7.5 units of capital goods ?

Answer:

  (5.5, -13.5)

Step-by-step explanation:

Midpoint M satisfies ...

  M = (S +T)/2

So ...

  2M = S + T

  2M -T = S

  2(5, -8) -(4.5, -2.5) = S = (10 -4.5, -16 +2.5)

  S = (5.5, -13.5)

Answer:

The answer is the function 3x+4y+5=0 is Slanted

Step-by-step explanation:

To be able to to know if this function is horizontal, vertical or slanted we should look at the gradient.

If the gradient is zero, then the line is horizontal.

If the gradient is infinite, then the line is vertical.

if not, then the line is slanted

We can look the gradient by the general form equation of a line:

y = mx + c

where y = dependent variable, x = independent variable, m = gradient, c = intercept.

With our equation, we can change things around to get the general form equation:

3x + 4y + 5 = 0

4y = 3x - 5

[tex]y = \frac{3}{4}x - \frac{5}{4}[/tex]

Where the gradient is 3/4

Therefore, as the gradient is a number other than zero or infinite, we know that this function is slanted.

Answer:

The coordinates of point B are (6,7).

Step-by-step explanation:

Given points are

Blue = A(-4,8)

Purple = M(1,7.5)

Green = B

It is given that point M is the midpoint of point A and B.

Let coordinates of points are (a,b).

Midpoint of two points is

[tex]Midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

[tex]M=(\dfrac{-4+a}{2},\dfrac{8+b}{2})[/tex]

Coordinates of midpoint are (1,7.5).

[tex](1,7.5)=(\dfrac{-4+a}{2},\dfrac{8+b}{2})[/tex]

On comparing both sides we get

[tex]1=\dfrac{-4+a}{2}\Rightarrow 2=-4+a\Rightarrow a=6[/tex]

[tex]7.5=\dfrac{8+b}{2}\Rightarrow 15=8+b\Rightarrow b=7[/tex]

Therefore, the coordinates of point B are (6,7).

b. The radius of the first ferris wheel was 179% of the radius of the navy pier ferris wheel

c. The wheel was moving at 0.70 [tex]\frac{rad}{min}[/tex]

Step-by-step explanation:

Navy pier wheel circumference = Cn

First ferris wheel circumference = Cf

Cn = 0.56*Cf

a.

Circumference Perimeter = 2*π*Radius

Navy pier wheel radius = Rn

First ferris wheel radius = Rf

Cn = 0.56*Cf

2*π*Rn = 0,56*2*π*Rf        (equation 1)

dividing both sides by 2π

Rn = 0,56*Rf

b.

From equation 1

2*π*Rn = 0,56*2*π*Rf

dividing both sides by 2π

Rn = 0.56*Rf

dividing both sides by 0.56

Rf = [tex]\frac{1}{0.56}[/tex]*Rn

Rf = 1.79*Rn

Answer:

Bob wins

Step-by-step explanation:

Think first in a simpler case. In a 2x2 matrix the determinant is zero if two columns or rows are proportional. So Alice writes the first number, then Bob write the same number in the same column but in the other row. Bob repeat the procedure after Alice's second number, and win.

If the matrix is nxn where n is even (like 2008) Bob will win following the previous procedure. Alice writes a number anywhere, Bob writes the same number in the same column in the above (or below) row.  Every time Alice write a number in the same row as her first one, Bob copy that number in the above (or below) row. Any other rows are not important, i.e, the determinant will be zero with any values in them.

Data

Southern ocean area =  7.85 x 10⁶ square miles

Difference between areas Indian ocean  = 1.865 x 10⁷ square miles

and the southern ocean

Process

a) To find the area of the Indian ocean we need to sum of the values of the area of the Southern ocean and the area of the difference between the Indian ocean and the southern ocean.

b)

      Area of the Indian Ocean = 1.865 x 10⁷ + 7.85 x 10⁶

                                                 = 2.65 x 10⁷ square miles

Answer:

The area of the Indian ocean is [tex]2.65\times 10^7[/tex]      

Step-by-step explanation:

Given : The area of the southern ocean is about [tex]7.85\times 10^6[/tex] square miles. The difference between the areas of the Indian ocean and the southern ocean is about [tex]1.865\times 10^7[/tex] square miles.

To find : Explain how to find the area of the Indian ocean. Then find the area.

Solution :

The area of the southern ocean is about [tex]7.85\times 10^6[/tex] square miles.

i.e. [tex]A_s=7.85\times 10^6[/tex]

The difference between the areas of the Indian ocean and the southern ocean is about [tex]1.865\times 10^7[/tex] square miles.

i.e. [tex]A_i-A_s=1.865\times 10^7[/tex]

Substitute the value of [tex]A_s[/tex]

[tex]A_i-7.85\times 10^6=1.865\times 10^7[/tex]

[tex]A_i=1.865\times 10^7+7.85\times 10^6[/tex]

[tex]A_i=1.865\times 10^7+0.785\times 10^7[/tex]

[tex]A_i=(1.865+0.785)\times 10^7[/tex]

[tex]A_i=2.65\times 10^7[/tex]

Therefore, The area of the Indian ocean is [tex]2.65\times 10^7[/tex]

Answer:

The expected value is 5.

Step-by-step explanation:

As we can see, X=Y+Z. Then, by the linearity of the expected value operator, we have that

[tex]E(X)=E(Y)+E(Z).[/tex]

Observe that Y and Z have countable sets of outcomes (1,2,3,....) then,

[tex]E(X)=\sum^\infty_{n=1}nP(Y=n)[/tex],

[tex]E(Z)=\sum^\infty_{n=1}nP(Z=n)[/tex],

Then:

[tex]E(Y)=\sum^\infty_{n=1}nP(Y=n)=\sum^\infty_{n=1}n(\frac{1}{2} )^n=\\\\\sum^\infty_{m=1}\sum^\infty_{n=m}(\frac{1}{2} )^n=\sum^\infty_{m=1}(\frac{1}{2} )^{m-1}=\sum^\infty_{m=0}(\frac{1}{2} )^{m}=2.[/tex]

[tex]E(Z)=\sum^\infty_{n=1}nP(Z=n)=\frac{1}{3}\sum^\infty_{n=1}n(\frac{2}{3} )^{n-1}=\frac{1}{3}\sum^\infty_{m=1}\sum^\infty_{n=m}(\frac{2}{3} )^{n-1}[/tex]

Observe that, by the geometric series formula:

[tex]\sum^\infty_{n=m}(\frac{2}{3} )^{n-1}=\sum^\infty_{n=1}(\frac{2}{3} )^{n-1}-\sum^{m-1}_{n=1}(\frac{2}{3} )^{n-1}=3-\sum^{m-1}_{n=1}(\frac{2}{3} )^{n-1}=\\\\3-\sum^{m-2}_{n=0}(\frac{2}{3} )^{n}=3-\frac{1-(\frac{2}{3})^{m-1} }{1-\frac{2}{3}}=3(\frac{2}{3})^{m-1}[/tex]

Therefore

[tex]E(Z)=\frac{1}{3}\sum^\infty_{m=1}\sum^\infty_{n=m}(\frac{2}{3} )^{n-1}=\frac{1}{3}\sum^\infty_{m=1}3(\frac{2}{3})^{m-1} =\\\\ \sum^\infty_{m=1}(\frac{2}{3})^{m-1} = \sum^\infty_{m=0}(\frac{2}{3})^{m} =3.[/tex]

Finally, E(X)=E(Y)+E(Z)=2+3=5.

Using the binomial distribution, it is found that the expected value of the total number of tosses is of 5.

For each coin, there are only two possible outcomes, either it is heads, or it is tails. The outcome of a coin is independent of any other coin, hence the binomial distribution is used to solve this question.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected number of trials until q successes is:

[tex]E_s(X) = \frac{q}{p}[/tex]

For coin A, we obtain Heads with probability 1/2, hence:

[tex]E_{sA}(X) = \frac{1}{\frac{1}{2}} = 2[/tex]

For coin B, we obtain Heads with probability 1/3, hence:

[tex]E_{sB}(X) = \frac{1}{\frac{1}{3}} = 3[/tex]

2 + 3 = 5, hence, the expected value of the total number of tosses is of 5.

Answer:

Security B is riskier than Security A.

Step-by-step explanation:

Security A and B have the same historical average annual return which is 7%, meaning that both of them have had the same results over the years.

However, the standard deviation of A is 3% and the standard deviation of B is 9%, therefore we can conclude that Security A is safer than Security B because a low standard deviation indicates that the annual returns tend to be close to the average (mean), while a high standard deviation indicates that the annual returns are spread out over a wider range of values.

For example:

Security A has this values over the years:

6, 7, 8, 7 where mean is 7.

Security B has this values over the years:

1, 13, 4, 12 where the mean is also 7.

But, A has a lower standard deviation and B a higher one, therefore, Security B is riskier.

Answer:

total management fee is $16200

Step-by-step explanation:

given data

leases = $60000 per year

time = 7 year

fees 1st year = 7%

fees 2nd and 3rd year = 5%

fees remaining year = 3%

to find out

total management fee

solution

we find here commission for each here

for 1st year = 7% of $60000 = $4200   ............1

for 2nd and 3rd  year = 5% of $60000 = $3000   ............2

for remaining year = 3% of $60000 = $1800   ................3

and that is 4 year so fees = 1800 × 4 = $7200   ................4

now add all these to get total

total fees = 4200 + 3000 + 1800 + 7200

total fees = 16200

so total management fee is $16200

Sydney Blackwell's total management fee for a 7-year period, with varying annual rates applied to a $60,000 lease, amounts to $17,400.

Calculating Sydney's Total Management Fee

To calculate Sydney Blackwell's total management fee for managing an office building, we need to apply the corresponding percentage rates to the annual lease amount over the span of the management agreement. The lease amount is $60,000 per year, and the management agreement spans 7 years with varying fees each year.

Here's the breakdown of fees per year and total fee calculation:

Adding up the fees from all years:

$4,200 + $6,000 + $7,200 = $17,400

Therefore, the total management fee Sydney will receive over the 7-year period is $17,400.

You would set up a ratio for the two known sides to equal the known side and x:
