The US MNC hedge these payables by exchange currencies at a predetermined exchange rate and date in the future.

One way that the US MNC can hedge these payables is by using a forward contract. A forward contract is a customized agreement between two parties to buy or sell an asset at a specified price and date in the future.

Another way that the US MNC could hedge its payables is by using currency options. Currency options are contracts that give the buyer the right but not the obligation.

The buyer pays a premium to the seller of the option for this right. In this case, the US MNC could purchase a currency option to sell 1 million dollars at a fixed exchange rate in the future, protecting itself from unfavorable currency fluctuations.

A third way that the US MNC could hedge its payables is by using currency futures. Currency futures are similar to forward contracts but are standardized and traded on exchanges.

Answer:

Difference between Joyce's and her brothers age is 10 years.

Step-by-step explanation:

Let,

x be the age of Joyce

y be the age of her brother

According to given statement;

x+y=24       Eqn 1

y = 2x+3    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x+2x+3=24

3x=24-3

3x=21

Dividing both sides by 3

\(\frac{3x}{3}=\frac{21}{3}\\x=7\)

Putting x=7 in Eqn 2

y = 2(7) + 3

y = 14+3

y = 17

Difference = 17 - 7 = 10 years

Hence,

Difference between Joyce's and her brothers age is 10 years.

we need to multiply this number by 100 to get the  as a percentage:

0.1806 * 100 = 18.06%

The probability of choosing a senior can be calculated using the formula:

P(senior) = (102/562) * 100

P(senior) = 18.06%

This means that there is an 18.06% chance of choosing a senior if a student is randomly selected from the school.

First, we need to calculate the total number of students in the school by adding together the number of students in each class:

Total = 165 + 145 + 114 + 102 = 562

Next, we need to calculate the probability of choosing a senior by taking the number of seniors enrolled in the school (102) and dividing it by the total number of students in the school (562).

102/562 = 0.1806

Finally, we need to multiply this number by 100 to get the probability as a percentage:

The equation of the line perpendicular to y = (1/3)x + 65 through the point (7, 6) is y = -3x + 27. The equation of the line perpendicular to y = (-2/3)x + 65 through the point (-8, 1) is y = (3/2)x + 13.

To find the equation of a line perpendicular to a given line, we need to determine the slope of the perpendicular line.

For the line given by the equation y = (1/3)x + 65, the slope is 1/3.

To find the slope of the perpendicular line, we take the negative reciprocal of the original slope. So, the slope of the perpendicular line is -3/1 or -3.

Using the point-slope form of the equation of a line, we can write the equation of the line perpendicular to y = (1/3)x + 65 through the point (7, 6) as follows:

y - y1 = m(x - x1)

where (x1, y1) = (7, 6) and m = -3. Plugging in the values, we get:

y - 6 = -3(x - 7)

Expanding and simplifying, we have:

y - 6 = -3x + 21

Moving terms around, we get the final equation:

y = -3x + 27

Therefore, the equation of the line perpendicular to y = (1/3)x + 65 through the point (7, 6) is y = -3x + 27.

Now, let's find the equation of the line perpendicular to y = (-2/3)x + 65 through the point (-8, 1).

The given line has a slope of -2/3. The perpendicular line will have a slope that is the negative reciprocal of -2/3, which is 3/2.

Using the point-slope form, we can write the equation of the line perpendicular to y = (-2/3)x + 65 through the point (-8, 1):

y - y1 = m(x - x1)

where (x1, y1) = (-8, 1) and m = 3/2. Substituting the values, we have:

y - 1 = (3/2)(x - (-8))

Simplifying further:

y - 1 = (3/2)(x + 8)

Expanding and rearranging:

y - 1 = (3/2)x + 12

Moving terms around, we get:

y = (3/2)x + 13

Thus, the equation of the line perpendicular to y = (-2/3)x + 65 through the point (-8, 1) is y = (3/2)x + 13.

The total cost of the 40 codfish is 40 * 10 = 400 shillings.

The total cost of the 59 salmon is 59 * 30 = 1770 shillings.

The total cost of the 1 grouper is 300 shillings.

The total number of fish sold is 40 + 59 + 1 = 100.

The total cost of all the fish is 400 + 1770 + 300 = 2470 shillings.

Therefore, the average price paid per fish is 2470 / 100 = 24.7 shillings.

To find the average price paid per fish, we need to calculate the total cost of all the fish and divide it by the total number of fish sold. The total cost is obtained by multiplying the quantity of each type of fish sold by its price and then summing up the individual costs.

In this case, we have sold 40 codfish at 10 shillings each, which gives a total cost of 400 shillings, 59 salmon at 30 shillings each, which gives a total cost of 1770 shillings, and 1 grouper for 300 shillings. Adding up these costs gives a total cost of 2470 shillings.

Dividing this by the total number of fish sold (100) gives us the average price paid per fish, which is 24.7 shillings.

To solve the given system of equations using the reduced row echelon form, we will write the augmented matrix corresponding to the system and perform row operations to obtain the reduced row echelon form.

Answer :  x = t, y = 3/2 - t ,z = s

The augmented matrix for the system is:

[ -2  -2  -4  -6  | -3 ]

[ -1   0   2   1  |  0 ]

[ -2  -3   1   0  |  4 ]

[  0   0   4   0  | -1 ]

Using row operations, we can transform this matrix into reduced row echelon form:

1. Replace R2 with R2 + 2R1:

[ -2  -2  -4  -6  | -3 ]

[  0  -2  -2  -4  | -3 ]

[ -2  -3   1   0  |  4 ]

[  0   0   4   0  | -1 ]

2. Replace R3 with R3 + 2R1:

[ -2  -2  -4  -6  | -3 ]

[  0  -2  -2  -4  | -3 ]

[  0  -7  -7 -12  |  5 ]

[  0   0   4   0  | -1 ]

3. Replace R2 with R2/(-2):

[ -2  -2  -4  -6  | -3 ]

[  0   1   1   2  |  3/2 ]

[  0  -7  -7 -12  |  5 ]

[  0   0   4    0 | -1 ]

4. Replace R3 with R3 + 7R2:

[ -2  -2  -4  -6  | -3 ]

[  0   1   1   2  |  3/2 ]

[  0   0   0 -5   |  34/2 ]

[  0   0   4   0  | -1 ]

5. Replace R4 with R4 - (4/5)R3:

[ -2  -2  -4  -6  | -3 ]

[  0   1   1   2  |  3/2 ]

[  0   0   0 -5   |  34/2 ]

[  0   0   0   0  | -49/10 ]

Now, the matrix is in reduced row echelon form. Let's interpret it back as a system of equations:

-2x - 2y - 4z = -3

    y +  z =  3/2

             0 =  34/2

             0 = -49/10

The last two rows indicate that 0 = 34/2 and 0 = -49/10, which are contradictory statements. This means that the system is inconsistent, and there is no solution that satisfies all three equations simultaneously.

Therefore, there are no values of x, y, and z that satisfy the system of equations.

If we parametrize our answer using the free variables of the system, we have:

x = t

y = 3/2 - t

z = s

Where t and s are arbitrary parameters.

Step-by-step explanation:

Given

\(AB = 11\)

\(BC = 7\)

See attachment

Required

Determine \(\angle ABC\)

\(\angle ABC\) implies that we calculate the angle at B.

Given that:

\(AB = 11\) --- Hypotenuse

\(BC = 7\) --- Adjacent of B

We apply cosine formula

\(\cos(B) = \frac{Adjacent}{Hypotenuse}\)

\(\cos(B) = \frac{BC}{AB}\)

\(\cos(B) = \frac{7}{11}\)

\(\cos(B) = 0.6364\)

Take arccos of both sides

The price of the watch before the discount is calculated to be £24.44.

As the total price of the watch and a pair of trainers is £53. 55 and the price of the trainer before the discount was £38, we first calculate the price of the trainers after the discount as follows;

discount on a pair of trainers = 15/100 × 38 =  £5.7

cost of trainers after discount =  £38 - 5.7 =  £32.3

Now the price of the watch after the discount can be calculated by subtraction as follows;

price of watch after discount = total price - price of trainers after discount

price of watch after discount =  £53. 55 - £32.3

price of watch after discount = £21.25

Now the price of the watch before the discount can be calculated as follows;

price of watch before discount = £21.25 × 15/100

price of watch before discount = £21.25 + £3.1875

price of watch before discount = £24.44

Answer: 2/5

Explanation: Ask if you want an explanation!

      The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.

Finding the Slope

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)      

                                          =  (5 - 1) ÷ (8 - (-2))    

                                          =   ⁴/₁₀

                                          = ²/₅  

Checking my answer:

We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y - 1 =  ²/₅ (x + 2)

In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

The estimated regression equation suggests that one additional young child decreases the probability that the mother works by 1 percentage point (coefficient: -0.01). Therefore, the null hypothesis states that one additional young child decreases the probability that the mother works by 3 percentage points.

To calculate the t-statistic for testing the null hypothesis, we need to compare the estimated coefficient (-0.01) with its standard error (0.02). The formula for the t-statistic is given by t = (coefficient - hypothesized value) / standard error.

In this case, the hypothesized value is -0.03 (3 percentage points decrease). Plugging the values into the formula, we have t = (-0.01 - (-0.03)) / 0.02 = 0.02 / 0.02 = 1.Therefore, the t-statistic associated with the null hypothesis that one additional young child decreases the probability that the mother works by 3 percentage points is 1.

The estimated regression equation suggests that one additional young child decreases the probability that the mother works by 1 percentage point. To test the null hypothesis that one additional young child decreases the probability by 3 percentage points, we calculate the t-statistic. The t-statistic compares the difference between the estimated coefficient and the hypothesized value (3 percentage points) relative to the standard error of the coefficient. In this case, the t-statistic is calculated to be 1.

A t-statistic of 1 indicates that the estimated coefficient is one standard error away from the hypothesized value. In statistical hypothesis testing, we compare the t-statistic to critical values based on the significance level to determine whether the null hypothesis can be rejected or not. If the calculated t-statistic exceeds the critical value, we can reject the null hypothesis.

To find the number of ways, we can use the concept of permutations.

In this case, we have five players and three positions. Since each position can only be occupied by one player, we need to find the number of permutations of five players taken three at a time.

The formula to find the number of permutations is \(P(n, r) = n! / (n - r)!.\)

Using this formula, we can calculate the number of ways as follows:

\(P(5, 3) = 5! / (5 - 3)!\)
