The statement which is not true is a. Passive political risk management discourages managers from fully or partially hedging their bets against exposure to political hazards

Passive political risk management does not deter managers from fully or partially hedging their bets against political risk exposure. This management describes a strategy for controlling political risk that involves altering how a firm carries out a business to reduce political risk. This is generally performed without necessarily using financial instruments to safeguard against any degree of political risk.

It may entail taking necessary steps to spread the firm's operations across other geographies and regions, choosing joint venture partners with strong political influence, determining local contacts, and preserving strong ties with local individuals associated with politics. Even if a firm doesn't use active hedging tactics, these activities can efficiently assist it to lessen its exposure to political risk.

The required value of x for the diagonals of parallelogram is 8.

Let ABCD be the parallelogram, and let the diagonals AC and BD intersect at point E.

We know that in a parallelogram, the diagonals bisect each other. So, we have:

AC = 2AE and BD = 2BE

We are given that AC = 4x + 2 and BD = 5x - 6. Substituting in the above equations, we get:

2AE = 4x + 2 and 2BE = 5x - 6

Dividing both sides by 2, we get:

AE = 2x + 1 and BE = (5x - 6)/2

Since AE and BE are the same length (they are both half the length of the diagonals), we have:

2x + 1 = (5x - 6)/2

Multiplying both sides by 2, we get:

4x + 2 = 5x - 6

Subtracting 4x from both sides, we get:

8 = x

Therefore, the value of x is 8.

The length of the ramp that must cover the horizontal distance is 13.13 feet.

Given the data in the question, this forms a right-triangle.

To solve for the length of the ramp, we use  trigonometric ratio

Cosine = Adjacent / Hypotenuse

Plug in the values

cos( 8° ) = 13ft / hypotenuse

Hypotenuse = 13ft / cos( 8° )

Hypotenuse = 13.13 ft

Therefore, the ramp's length is 13.13 ft.

The probability of being assigned a general practitioner or a doctor under the age of 50 is 11/19 or approximately 0.5789 (rounded to four decimal places).

We are given that there are 5 general practitioners (GPs) out of 19 doctors in the hospital, which means that the probability of being assigned a GP is 5/19.

We are also given that there are 9 doctors under the age of 50 out of the 19 doctors in the hospital, which means that the probability of being assigned a doctor under the age of 50 is 9/19.

However, we need to subtract the probability of being assigned a doctor who is both a GP and under the age of 50 because this group is counted twice in the above probabilities.

We are given that there are 3 doctors who are both GPs and under the age of 50. Therefore, the probability of being assigned a doctor who is both a GP and under the age of 50 is 3/19.

To use the inclusion-exclusion principle, we add the probabilities of being assigned a GP and being assigned a doctor under the age of 50, and then subtract the probability of being assigned a doctor who is both a GP and under the age of 50.

P(GP or Under 50) = P(GP) + P(Under 50) - P(GP and Under 50)

The solution of the given system of equations 6x+3y=8 and 8x+4y=-1 is x=0 and y==-8/9

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitutes solutions of the system. (5, 4) is a solution of the first equation, but not the second.

We are given that;

The equation 1;  6x+3y=8

The equation 2; 8x+4y=-1

Now,

In equation 1

6x=8-3y

x=(8-3y)/6

Substituting the value of x in equation 2

8((8-3y)/6)+4y=-1

4((8-3y)/3)+4y=-1

(8-3y)/3)+4y=-1/4

8-3y+12y=-3/4

8+9y=-3/4

9y=-3/4-8

9y=-3-32/4

9y=-35/4

y=-32/36=-8/9

Putting the value of y in equation 1

6x+3(-8/9)=8

According to the given information the formula for f(x) in term of x is  f(x) = (4/5)x - 4.

A function is a relationship between a number of inputs and outcomes. Simply described, a function is an association between inputs where each input is linked to exactly one output. There is a range, codomain, as well as domain for every function. A function is commonly referred to as f(x), where x is in fact the input.

When looking at a graph, we use a procedure known as the Vertical Line Test to determine whether a function is indeed a function. Simply drawing a vertical line will reveal if the graph is a function if it touches it once.

4x - 5y = 20

Subtracting 4x from both sides

-5y = -4x + 20

Add the 33 to both sides. (The -33 will cancel out)

Now you are left with 6x = 70

Divide both sides by 6.

x = 11.67 (rounded by the hundredth) (11.66666...)

Step-by-step explanation:

Let's call the number of markers in each large box "x."

After giving away 15 markers to each of 3 teachers, there were 90 markers left, so:

x - (15 * 3) = 90

Adding 45 to both sides:

x = 135

So, each large box originally contained 135 markers.

The definition of the term was given as the collection of all positive integers, which is the same as the collection of all natural numbers. The concept of integer was expanded to include negative integers as the significance of those numbers came to be realized through time.

Let's call the length of the longer rope piece x and the length of the shorter rope piece y. We know that:

x + y = 5 (the total length of the rope is 5 feet)

And from the problem statement, we have:

3x - 7 = 5y

Now we can use the first equation to solve for y:

y = 5 - x

Substituting this expression for y into the second equation:

3x - 7 = 5(5 - x)

Expanding the right side:

3x - 7 = 25 - 5x

Adding 5x to both sides:

8x - 7 = 25

Adding 7 to both sides:

8x = 32

Dividing both sides by 8:

x = 4

So the length of the longer rope piece is 4 feet.
