Answer:

The thief has a 0.11% probability of hitting the pin code on the first try.

Explanation:

Simply, if the ATM card has a 3-digit code that can be repeated, and the board has 9 numbers (for example, from 1 to 9), we must start from the smallest number that could be formed with these numbers to the highest number that these numbers could also compose, which in the case would be 111 and 999. Then, 889 different numbers could be formed (it is the distance between 111 and 999), with which the possibility of hitting the key to the first attempt would be 1 in 889 times, or 1/889.

To take the probability to a percentage, we must know that 889 / 8.89 gives 100. Therefore, dividing 1 / 8.89 we will know the percentage of probabilities of hitting the key on the first attempt: 1 / 8.89 = 0.11.

This shows us that the thief has a 0.11% probability of hitting the key on the first try.

Rufina [12.5K]

The equation for facilities cost (fc) as a function of student credit hours is 350000 + .60 per credit hour

<h3>How are facility costs calculated?</h3>

Ongoing operating expenses for the facility consist of property taxes, utilities, site maintenance and landscaping, insurance, and facility maintenance and repair costs. Add up the total amount spent on each expense category to determine its cost. Breaking down building costs reveals how much it really costs to run a business. More importantly, there's information about potential savings. Examples include building and equipment depreciation, operation and maintenance, administrative assistance, library services, and student services.

The variable cost per student credit hour = change in cost/change in credit hours

= [530000 - 500000] / [300000 - 25000]

= 30000 / 50000= $ .60 per credit hour

Fixed cost at highest activity = 530000 - [300000 * 0.6]

= 530000 - 180000

= 350000 Cost function

= 350000 + .60 per credit hour

Leto [7]

Answer:

Total cost per unit is $77

Explanation:

Fixed manufacturing overhead per unit = Total fixed manufacturing overhead ÷ Number of units

= $478,800 ÷ 34,200 = $14 per unit

Fixed selling and administrative expenses per unit = Total Fixed selling and administrative expenses ÷ Number of units

= $171,000 ÷ 34,200 = $5 per unit.

Total cost per unit = Direct material + Direct labor + Variable manufacturing overhead + Fixed manufacturing overhead + Variable selling expenses + Fixed selling expenses

Total cost per unit = $15 + $5 + $11 + $14 + $5 + $5 = $55 per unit.

Markup = 40% of total cost = $55 × 40% = $22

Therefore, total selling price per unit = Cost per unit + Markup

= $55 + $22 = $77 per unit.
