The equation is:
h  + c = 345 \\  \\ c = 2h
Replace c with 2h:
h + 2h = 345 \\  \\ 3h = 345
Divide both sides by 3:
h = 115

The following is an account for a production department, showing its costs for one month:
deff fn [24]

Answer:

option (b)  $9,360

Step-by-step explanation:

Given:

Goods in Process Inventory

Balance = $6,300

Direct materials = $22,500

Direct labor = $17,100

Overhead = $11,700

The cost of units in ending goods in process inventory = $5,490

The cost of started and completed units = $42,750

Now,

The cost of total Goods in Process Inventory will be

= Balance + Direct materials + Direct labor + Overhead

= $6,300 + $22,500 + $17,100 + $11,700

= $57,600

also,

Cost of units to be transferred out

= cost of total Goods in Process Inventory - ( cost of units in ending goods in process inventory )

= $57,600 - $5,490

= $52,110

Thus,

Cost of Completed Goods in Beginning Inventory

= Cost of units to be transferred out - cost of started and completed units

= $52,110 - $42,750

= $9,360

Hence, the answer is option (b)  $9,360

URGENT PLEASE HELP Select the correct solution set. x + 17 ≤ -3 {x | x ≤ -20} {x | x ≤ 14} {x | x ≥ -20}
grigory [225]

Answer:

The correct answer is the first solution set.

Step-by-step explanation:

If we substitute -20 into the equation we get

-20+17≤-3

-3≤-3

So,the inequality is right.

We can check the second one

14+17≤-3

31≤3 The inequality is false.

We can check the last one

-20+17≤-3

-3≤3 It works however there is a difference between the first one and the last one and that is the sign.For the first one there x≤-20 meaning the greatest number x can be is -20.For the last one x≥-20 which means -20 is the least value x can be.

If we substitude -21 into the equation we get

-21+17≤-3

-4≤-3

The inequality is false because -4 is not smaller than -3.

So,the right answer is the first solution set.

The electric cooperative needs to know the mean household usage of electricity by its non-commercial customers in kWh per day. A
Montano1993 [528]

Answer: (14.4, 17.2)

Step-by-step explanation: We are to construct a 98% confidence interval for mean household usage of electricity.

We have been given that

Sample size (n) = 872

Sample mean (x) = 15.8

Population standard deviation (σ) = 1.8

The formulae that defines the 98% confidence interval for mean is given below as

u = x + Zα/2 × σ/√n...... For the upper limit

u = x - Zα/2 × σ/√n...... For the lower limit

Zα/2 = critical value for a 2% level of significance in a two tailed test = 2.33

By substituting the parameters we have that

For upper tailed

u = 15.8 + 2.33 × (1.8/√872)

u = 15.8 + 2.33 (0.6096)

u = 15.8 + 1.4203

u = 17.2

For lower tailed

u = 15.8 - 2.33 × (1.8/√872)

u = 15.8 - 2.33 (0.6096)

u = 15.8 - 1.4203

u = 14.4

Hence the 98% confidence interval for population mean usage of electricity is (14.4kwh, 17.2kwh)
