<span>Assuming a normal distribution the noise level is below 44dB 90% of the time. Looking up the standard deviation that goes along with .01 on a normal distribution chart, we find that 2.33 standard deviations is the answer. Given the standard deviation of six we turn this in to deviation in decibels from the mean: 6*2.33 = 13.98 Add this to the mean to get 30+13.98=43.98 which we round to 44dB</span>

Misterio Company uses a standard costing system. During the past quarter, the following variances were computed:
kotykmax [81]

Answer:

1. Total hours allowed = 40,000

  Actual direct labour hours worked = 52,000.

2. Standard hourly rate = $10

   Actual rate = $10.2

3. Actual output= 20,000 units

Explanation:

The variable overhead efficiency variance in hours= variable overhead efficiency variance in Dollar/Variable overhead standard rate

= $24,000/$2= 12,000 hours unfavorable

Let the actual hours be V

Let the standard hours for the actual output achieved be = V

The actual hours worked = 130% of the standard hours allowed

Actual hours =130% × V = 1.3V

1.3V - V= 12,000

V=12000/0.3=40,000

Total hours allowed = 40,000

Actual labour hours= 130%× 40,000=52,000

Total hours allowed = 40,000

Actual direct labour hours worked = 52,000.

Standard labour rate =

Labour effciency variance in Dollar /Labour efficiency variance in hours

= 120,000/12,000=$10

Standard hourly rate = $10

Rate variance = (Actual rate - standard rate)× Actual hours

Let the actual rate be = Y

      10,400   = ( Y - 10) × 52,000

10,400= 52000Y- 520,000

Y= (520,000 + 10,400)/52,000=10.2

Actual rate = $10.2

Standard labour hours for actual output = Actual output × standard hours

Let the actual output be = m

40,000 = m × 2

m= 40,000/2= 20,000 units

Actual output= 20,000 units

The night before a midterm exam, you decide to go to the movies instead of studying for the exam. You score 60 percent on your e
Aleks [24]

Answer:

10% of exam score

Explanation:

Opportunity Cost is the cost of next best alternative, foregone (sacrifised)  while making a choice.

Example : If a person has option to have an apple or an orange, & choses to have apple. The opportunity cost of having an apple is the sacrifised orange.

Given : A night before mid time exam, spent while watching movies - later lead to fall in exam grade from 70 % to 60%

The opportunity cost of movies watched, is the sacrifised grade of exam, which would have gotten, if the time would have spent in studying. The corresponding grade lost = 70% grade achievable - 60% grade achieved. Hence, the opportunity cost = 10% of exam score.
