Let ∑ = {a,b}, and let L be the language over ∑:
L ={ w € ∑+ |w is even, and w contains at least one a in the first half and exactly one b in the second half }
Give a context-free grammar (CFG) for L, and briefly explain how it works to correctly represent the language. There are no additional requirements for your solution other than what is stated here, except the usual guidance to make sure your answer is clear and understandable and avoids too much unnecessary complexity. In particular, there is no credit for the grammar being unambiguous (if possible.)

Answer:

D.inflows are greater than or equal to outflows.

Explanation:

A budget is a financial plan used for the estimation of revenue and expenditures of an individual, organization or government for a specified period of time, often one year. Budgets are usually compiled, analyzed and re-evaluated on periodic basis.

A balanced budget is a type of budget in which inflows are greater than or equal to outflows. Thus, when cash inflows (income) is greater than or equal to cash outflows (expenses), a budget is said to be balanced.

The first step of the budgeting process is to prepare a list of each type of income and expense that will be integrated or infused into the budget.

This ultimately implies that, before preparing a budget, it is of utmost importance to know total income (inflows) and expenses (outflows).

The final step to be made by the management of an organization in the financial decision-making process is to make necessary adjustments to the budget.

In conclusion, the benefits of having a budget is that it aids in setting goals, earmarking revenues and resources, measuring outcomes and planning against contingencies. It is typically used by individuals, government, organizations or companies due to the fact that, it's tied directly to the strategy and tactics of a company on an annual basis. Also, it is used to set a budget for marketing efforts while anticipating on informations about the company.

Explanation:

When the values are pushed to the stack they would end up in the stack in the same order as they go in.

1 7 4 6 10 9

when elements are popped from a stack they are removed from the end to the beggining of the stack, and since these elements are being added to the priorityQueue then priQue will have the following order

9 10 6 4 7 1

this will also be the order that the numbers will be printed out from left to right since priorityQueue remove method, removes the elements from left to right.

Explanation:

The mass percent of hydrogen in CH₄O is 12.5%.Mass percent is the mass of the element divided by the mass of the compound or solute.

Mass percent is the mass of the element divided by the mass of the compound or solute.

Step 1: Calculate the mass of the compound.

mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu

Step 2: Calculate the mass of hydrogen in the compound.

mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu

Step 3: Calculate the mass percent of hydrogen in the compound.

%H = (mH in mCH₄O / mCH₄O) × 100%

%H = 4.00 amu / 32.01 amu × 100% = 12.5%

The mass percent of hydrogen in CH₄O is 12.5%.

CO2 = 1.580 grams H2O = 0.592 grams Lookup the molar mass of each element in the compound Carbon = 12.0107 Hydrogen = 1.00794 Oxygen = 15.999 Calculate the molar mass of CH4O by adding the total masses of each element used. 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 Now calculate how many moles of CH4O you have by dividing by the molar mass. m = 1.15 g / 32.04146 g/mole = 0.035891 mole Now figure out how many moles of carbon and hydrogen you have. Carbon = 0.035891 moles Hydrogen = 0.035891 moles *

Therefore, The mass percent of hydrogen in CH₄O is 12.5%.

Its claim from the group indicates that perhaps the Internet can promote political participation by enabling citizens to communicate easily across geographic and social frontiers. The claim suggests that this exchange would in turn promote the creation of new consultative spaces or new modes of collective activity. By comparison, the authoritarian model emphasizes the role of technology in transforming citizens' and policy interactions. Ward (1997) states which online referenda and proposals are typically described as mechanisms of change.

Answer:

c. 16 17

Explanation:

Given

[tex]num = 14[/tex]

The above code segment

Required

The output

In the code segment, we have the following iterations:

for (int j = 0; j < arr.length; j++) and for (int k = 0; k < arr[0].length; k++)

The above iterates through all the elements of the array.

The if condition is true, only on two occasions

(i) When i = 0; j = 2

(ii) When i = 3; j = 0

i.e.

arr[0][2] = 14

arr[3[0] = 14

So, the result of the print statement is: j + k + arr[j][k]

(i) When i = 0; j = 2

j + k + arr[j][k]  = 0 + 2 + 14 = 16

(ii) When i = 3; j = 0

j + k + arr[j][k]  = 3 + 0 + 14 = 17

Hence, (c) 16 17 is true

If the computer is starting up and getting into windows then this means that the processor itself is not dead. First, check to see if the processor fan is spinning correctly when turning on the computer. If it is, then you will need to remove it, and make sure that the processor is perfectly slotted within the cpu slot and that no pins are bent. If this is the case, then clean the cpu top with an alcohol swab and reapply thermal paste. If it is overheating due to any of these reasons it would cause the pc to power off in order to preserve the processor. If none of these fix the problem then it might be a faulty processor or a problem with another component such as the RAM or power cables.
