Synergy is obtained when the value created by two divisions operated separately and independently is greater than the value that would be created by two divisions cooperating. The given statement is False.

The statement is false. Synergy is a term used to describe the benefits that can be achieved when two or more parts of a business work together to create more value than they could on their own. In other words, when two divisions cooperate and work together, the combined value they create is greater than the value that would be created if they worked independently and separately.

For example, if a company has a marketing division and a sales division, these two divisions could work independently to achieve their goals. However, if they work together and share information, resources, and expertise, they can create more value by developing more effective marketing strategies that lead to increased sales. In this case, the combined value of the marketing and sales divisions working together is greater than the value they could create if they worked independently.

Therefore, it is incorrect to say that synergy is obtained when two divisions operate separately and independently to create greater value than they would if they cooperated.

We can find that this probability is 0.99994, rounded to five decimal places.

Based on the given statistic, we know that 80% of vehicles using the Lincoln Tunnel use E-ZPass. Therefore, we can expect that out of the 12 randomly selected vehicles, 80% or 0.8 * 12 = 9.6 vehicles would use E-ZPass. Rounding to the nearest whole number, we would expect 10 of the 12 vehicles to use E-ZPass.

The mode of the distribution is 10, as this is the most frequently occurring value in the sample.

Since 10 out of 12 vehicles is the mode, the probability associated with the mode is the proportion of vehicles that use E-ZPass in the sample. Therefore, the probability associated with the mode is 10/12 or 0.833, rounded to three decimal places.

The probability of four or more vehicles using E-ZPass can be calculated using the binomial distribution. The probability of a single vehicle using E-ZPass is 0.8, and the probability of a single vehicle not using E-ZPass is 0.2. The probability of four or more vehicles using E-ZPass is the sum of the probabilities of selecting 4, 5, 6, 7, 8, 9, 10, 11, or 12 vehicles that use E-ZPass. Using Excel or a calculator, we can find that this probability is 0.99994, rounded to five decimal places.

If Roland has Z-score for his test 0.6, the standard deviation for this set of test scores is 7.5

To find the standard deviation for this set of test scores, we can use the z-score formula:

Z-score = (X - μ) / σ

Where:
- Z-score is 0.6 (given)
- X is Roland's score of 70
- μ is the mean score of 65.5
- σ is the standard deviation we need to find

Now we can plug in the values and solve for σ:

0.6 = (70 - 65.5) / σ

Next, we can rearrange the equation to solve for σ:

σ = (70 - 65.5) / 0.6

Finally, calculate the standard deviation:

σ = 4.5 / 0.6

σ ≈ 7.5

We cannot get Equation B from Equation A as they are fundamentally different.

Equation A, 5x = 3x, is a linear equation with variables on one side and constants on the other side. To solve this equation for x, we can subtract 3x from both sides to get:

5x - 3x = 2x

Therefore, the solution to Equation A is x = 0 or x = any other real number.

On the other hand, Equation B, 5 = 3, is a statement of equality between two constants. There is no variable in this equation to solve for, and it is always false since 5 is not equal to 3.

The constant of proportionality between d and h is 3.75

Any function in which the dependent variable (y) is obtained by multiplying the independent variable (x) by a constant value is called the direct proportionality function. This function is also expressed in the form  [tex]( y = m * x)[/tex] and is more commonly called a linear function.

The value m is a constant and is known as the constant of proportionality or the slope of the line. It represents the inclination of the line to the abscissa axis, that is, the x-axis. If we talk about graphic representation, this linear function is a line with slope m that passes through the origin of coordinates, that is, the point 0 in x and 0 in y, which is the point (0,0).

Bethany finds the distance d with the help of equation d = 3.75*h, she travels this distance while walking for h number of hours.  When we compare it with the direct proportionality function y = m * x, then y is represented by the distance d, x is represented by the number of hours h, and slope m or the constant of proportionality is the number 3.75.

The effective interest method of amortization is a method used to allocate the cost of a bond over the bond's life, in order to determine the amount of interest expense to be recorded each period.

In the case of Bentley Corporation, since they issued $1,000,000 of 10-year, 8% bonds at 105, this means that they received $1,050,000 in cash from investors.

Since the market rate of interest was 7%, the bonds were sold at a premium, which means that the effective interest rate is less than the stated interest rate of 8%. The effective interest rate is the rate at which the present value of the bond's future cash flows equals the amount of cash received at the time of issuance.

Using the effective interest method of amortization, the premium of $50,000 will be amortized over the life of the bond, reducing the effective interest rate each year. The interest expense recorded on December 31, 2021, the first interest payment date, will be calculated as follows:

$1,050,000 x 7% = $73,500 (effective interest)
$73,500 - $80,000 (stated interest) = -$6,500 (amortization of premium)
$80,000 - $6,500 = $73,500 (interest expense)

The premium of $50,000 will be reduced by $6,500, leaving a balance of $43,500 at the end of the first year. This process will continue each year until the bond matures in 2031.

The number of ways the student can pull 5 integers out of the bucket in increasing order is 15,504.

To determine this, we can use the combination formula, which calculates the number of ways to choose k objects from a set of n objects, regardless of order. In this case, we want to choose 5 integers out of a set of 20 integers in increasing order, which means we can use the combination formula with repetition: C(n+k-1, k-1).

Substituting in our values, we get: C(20+5-1, 5-1) = C(24, 4) = (24232221)/(4321) = 15,504.

Therefore, there are 15,504 ways for the student to pull 5 integers out of the bucket in increasing order.

It is important to note that the order of the integers matters when counting the number of ways in which they can be chosen. In this case, the integers must be chosen in increasing order, which means we cannot count combinations where the integers are chosen in a different order.
