The journal entry for pension expense is recorded to reflect the cost of providing defined-benefit pension benefits to employees. This entry recognizes the expense and the corresponding increase in the pension liability.

To prepare the journal entry for pension expense, we need to consider the relevant balances related to the defined-benefit pension plan. The pension expense is typically calculated based on actuarial assumptions, such as the expected return on plan assets, discount rate, and projected benefit obligations.

The journal entry for pension expense includes debits and credits to various accounts. The debit side usually includes the pension expense account, which represents the cost incurred by the company for providing pension benefits to its employees. This expense is recognized in the income statement.

The compound inequality for the given situation is $2.75x + $4.25y ≥ $65 and $2.75x + $4.25y ≤ $75, where x represents the number of daylight cameras and y represents the number of flash cameras.

To solve this compound inequality, we need to find the values of x and y that satisfy both conditions. The inequality $2.75x + $4.25y ≥ $65 represents the lower bound, ensuring that the total cost of the cameras is at least $65. The inequality $2.75x + $4.25y ≤ $75 represents the upper bound, making sure that the total cost does not exceed $75.

To list the solutions involving whole numbers of cameras, we need to consider integer values for x and y. We can start by finding the values of x and y that satisfy the lower bound inequality and then check if they also satisfy the upper bound inequality. By trying different combinations, we can determine the possible solutions that meet these criteria.

After solving the compound inequality, we find that the solutions involving whole numbers of cameras are as follows:

(x, y) = (10, 10), (11, 8), (12, 6), (13, 4), (14, 2), (15, 0), (16, 0), (17, 0), (18, 0), (19, 0), (20, 0).

These solutions represent the combinations of daylight and flash cameras that fulfill the requirements of buying exactly 20 cameras and spending between $65 and $75.

Answer:

2a2b-6ab2+9ab+5 is right answer

The expression 2 + 5i - i( 3 - 6i ) simplified in a+bi form is -4 + 2i.

Given the expression in the question:

2 + 5i - i( 3 - 6i )

To simplify the expression 2 + 5i - i( 3 - 6i ), first, apply the distributive property to remove the parenthesis:

2 + 5i - i( 3 - 6i )

2 + 5i - i × 3 - i × - 6i

2 + 5i - 3i + 6i²

Note that: i²  is the same as (-1).

Hence:
2 + 5i - 3i + 6( -1 )

Simplifying, we get:

2 + 5i - 3i - 6

Collect and add like terms:

2 - 6 + 5i - 3i

-4 + 2i

Therefore, the simplified form is -4 + 2i.

The solutions to the equation \(x^2 + 10x + 12 = 36\) By factoring or applying the quadratic formula, we find the solutions: x = -4 and x = 6. Hence, the values of x that satisfy the equation are -4 and 6.

To solve the equation \(x^2 + 10x + 12 = 36\), we'll follow these steps:

36 should be taken out of both sides of the equation.

\(x^2 + 10x + 12 - 36 = 0\)

Simplifying the left side, we get:

\(x^2 + 10x - 24 = 0\)

To factor the quadratic equation, we need to find two numbers whose sum is 10 (coefficient of x) and whose product is -24 (constant term). These numbers are 4 and -6.

Rewrite the quadratic equation using the found numbers:

(x + 4)(x - 6) = 0

Use the zero product property, which specifies that at least one of the components must be zero if the product of two factors is zero. Set each element to zero and then calculate x as follows:

x + 4 = 0 or x - 6 = 0

For x + 4 = 0:

x = -4

The system of linear equations which has the rank of coefficient matrix equal to augmented matrix and equal to the number of unknowns, has only one solution called the unique solution.

Two types of system of equations exist- consistent and inconsistent.

Inconsistent means that it has no solution , i.e. the solution does not exist , here

Rank of augmented matrix is not equal to that of coefficient matrix.

Consistent system means a solution of the equation exists i.e.

rank of augmented matrix = rank of coefficient matrix.

Now, a consistent system can be of two types again - It may have a unique solution ,i.e.

rank of augmented matrix = rank of coefficient matrix = no. of unknowns

or an infinite number of solutions, where

rank of augmented matrix = rank of coefficient matrix < no. of unknowns   (here we need to assign an arbitrary value to a free variable to find its solutions).

For e.g. let us consider the system -

x + y+ z = 0

2x + 3y + 4z = 1

Since , (0,0,0) is obviously satisfying the equation and so is a solution to this system , the given system is a consistent system .

Also, for a system to be consistent , either a unique solution exists or an infinite number of solutions exist. There is no particular number of solutions.

Here, we see that (-1,1,0) is also a solution other than the zero solution.

We can clearly see that the number of unknown variables , x,y,z is 3 and the number of equations is 2.

Thus, The system if there are fewer equations than variables has infinite solutions, equal number of equations as the unknowns has the unique solution.

3) Yes it is reasonable because it indicates is that the igniters are more successful than already thought or it would be close to impossible to get those same results by chance.

1) We are told that the overall failure rate which is the percent of all igniters that fail to operate correctly is 15 percent = 0.15\.

Thus, percentage of success = 85% = 0.85

The probability that the first 30 super igniters selected using the testing process successfully launch rockets is;

P(X = 30) = (0.85)³⁰

= 0.0076

2) Given that the first 30 super igniters successfully launch rockets, the probability that the 1st failure occurs on the 31st or the 32nd super igniter tested if the failure rate of the super igniters is 15 percent is;

P(Y = 31)/P(X = 30) + P(Y = 32)/P(X = 30)

= [(0.15 * 0.85³⁰)/0.85³⁰] + [(0.15 * 0.85³¹)/0.85³⁰]

The probability of having 7 boys in a family with 7 children is 1 out of 128, as there is only one favorable outcome out of 128 total possible outcomes.

To find the probability, we need to calculate n(E) and n(S).

In this case, event E represents the scenario where all 7 children are boys. The sample space S consists of all possible permutations of boys and girls for the 7 children, which is 2^7 = 128.

This is because each child has 2 possibilities (boy or girl), and we multiply these possibilities for all 7 children.

Since event E includes only one specific outcome (all boys), n(E) is equal to 1. Therefore, both n(E) and n(S) are 1 and 128, respectively. The probability of having 7 boys is given by n(E)/n(S) = 1/128.

Step-by-step explanation:

The reorder point for bath towels at Chicago's Hard Rock Hotel is approximately 1,494 towels.

To calculate the reorder point, we need to consider the mean demand, lead time, and the desired service level. The mean demand for bath towels is given as 1,200 per day, and the standard deviation is 105 towels per day.

Since the hotel wants to maintain a 98% service level, we need to find the corresponding z-value from the standard normal distribution table. A 98% service level corresponds to a z-value of approximately 2.05.

To calculate the reorder point, we need to consider the lead time. In this case, the lead time is 4 days.

The formula to calculate the reorder point is:

Reorder point = Mean demand during lead time + (Z-value * Standard deviation of demand during lead time)

Calculating the mean demand during lead time:

Mean demand during lead time = Mean demand per day * Lead time

Mean demand during lead time = 1,200 towels/day * 4 days = 4,800 towel

Calculating the standard deviation of demand during lead time:

Standard deviation of demand during lead time = Standard deviation per day * √(Lead time)

Standard deviation of demand during lead time = 105 towels/day * √(4) = 210 towels

Substituting the values into the reorder point formula:

Reorder point = 4,800 towels + (2.05 * 210 towels) = 4,800 towels + 430.5 towels ≈ 1,494 towels

Therefore, the reorder point for bath towels at Chicago's Hard Rock Hotel is approximately 1,494 towels.
