The expected completion time of a project is 40 weeks and the variance of its critical path activities is 9.Project completion time is 42.0325 weeks.

Variance of its critical path activity 9 weeks.

Therefore, Standard deviation of its critical path activity = Square root ( variance) = Square root (9) = 3

Project completion time with 5% certainty means probability of project completion - 0./5 Corresponding z value for probability of 0.75 = NORMSINV ( 0.75) = 0.6745

Therefore, project completion time with 75% certainty = Expected completion time of the project .

Value x Standard deviation of critical path activity = 40 weeks * 0.6745 x 3 weeks = 40-2.0235 = 42.0325 weeks

zmey [24]

Answer:

$778460

Explanation:

Using the highlow method, we calculate the variable cost per unit,

  • VC / unit = 855460 - 651960 / 730000 - 545000  = $1.1per unit
  • The total fixed cost will be = 855460 - (1.1 * 730000) = $52460

The cost estimating equation will be,

  • Total cost at x number of unit = 1.1x + 52460

The cost of manufacturing supplies for the month of July will be,

  • Total cost (July) = 1.1(660000) + 52460   = $778460

elena-s [515]

Answer:

D. A checking account comes with a credit card.

Explanation:

A checking account is opened to facilitate regular bank transactions such as deposits, withdraws, cash transfers, payments, among others. There are no limits to the number of transactions that one can perform per period. Bank's fee and charges are applicable per transaction. To facilitate payments, withdrawals, and deposits, banks provide debit cards to customers.

Savings accounts are designed to help customers accumulate funds for future use. Banks limit withdrawals and offer interest payments to encourage customers to save. Savings accounts have fewer charges and don't come with debit cards.
