Answer:

a) 0.667

b) Yes

Explanation:

Data provided in the question:

Mean = 0.04 chip

Standard deviation, s = 0.003 chip

Lower Specification Limit, LSL  = 0.034

Upper Specification Limit, USL = 0.046

Now,

a) Capability Index = ( USL - LSL ) ÷ ( 6 × s )

or

Capability Index = ( 0.046 - 0.034 ) ÷ ( 6 × 0.003 )

= 0.667

b) Cpk = min( [( USL - Mean) ÷ ( 3s ) , ( Mean - LSL) ÷ ( 3s ))

or

Cpk = min( ( 0.046 - 0.04) ÷ (3 × 0.003 ),  ( 0.04 - 0.034 ) ÷ ( 3 × 0.003 ))

or

Cpk = min( ( 0.046 - 0.04) ÷ (3 × 0.003 ),  ( 0.04 - 0.034 ) ÷ ( 3 × 0.003 ))

or

Cpk = min( 0.667, 0.667 )

Therefore,

Cpk = 0.667

as Cp and Cpk are equal

Hence, it is ideal condition and process is capable

Since Anytime Pizza is open 24 hours a day, its pizza oven is constantly on and is, therefore, always using natural gas. However
netineya [11]

Answer: Mixed cost

Explanation:

The cost of the natural gas is a mixed cost. A mixed cost is the cost that combines two types of costs (fixed costs and variable costs). A mixed cost is made up of a fixed cost that doesn’t change when production volume changes and also the variable cost that changes when production volume changes.

Mixed costs are also known as semi variable cost. The natural gas is used constantly with the expense incurred on it continuous, therefore it's a fixed cost. Also, when there is no pizza, the usage of natural gas decreases so it's a variable cost. Since it has attribute of fixed and variable cost, it's a mixed cost.

elena-14-01-66 [18.8K]

Answer:

c. $12,175,000.

Explanation:

Given: Merchandise sold by Lang company= $12520000.

           Sales return and allowances= $270000.

           Discount= $140000.

While calculating net sales, freight out charges is not included as it an selling expense and it should be included while calculating Gross profit of the company.

Here, we have to find the last year net sales for Lang company.

∴ Net sales= sales\ revenue- (sales\ returns\ and\ allowances + sales\ discount)

⇒ Net sales = 12520000-(270000 + 75000) = 12520000 - 345000

∴Net sales= \$ 12175000

Lemur [1.5K]

Answer:

C. Statute of limitations.

Explanation:

Statute of limitations are laws which states the time limit of when legal proceedings must be initiated between concerned parties from the date in which alleged offence was perpetrated.

In statue of limitations, the time limit for somebody is wronged to initiate legal action is not fixed in all jurisdiction. It means that depending on the nature of the alleged offense under statute of limitation, time allowed to institute legal actions varies.

Example of statue of limitation is that for certain states, the time limit to initiate legal case say on fraud is two years. It means that one must bring up the case in a court of law within the stipulated two years period. Once the two year grace elapse, one can no longer sue for fraud in the court of law.

Although there is no time limit for certain offence like murder case, sex offence with minor etc.

As in the case above, the judge threw away the case because according to the law of statute of limitation, a party that is wronged can only sue the wrong doer within the stipulated time as spelt out within the jurisdiction where the alleged offence was committed.

Naddika [18.5K]

Answer:

The rate is greater than 8%

Explanation:

Given

\small I = 1,000 \left (\left (1+\frac{r}{100} \right )^{n}-1 \right )

<em>Missing part of question</em>

I =210

n =2

Required

Is r > 1

We have:

\small I = 1,000 \left (\left (1+\frac{r}{100} \right )^{n}-1 \right )

Substitute values for r and I

210 = 1,000 \left (\left (1+\frac{r}{100} \right )^{2}-1 \right )

Divide both sides by 1000

0.210 = \left (\left (1+\frac{r}{100} \right )^{2}-1 \right )

Add 1 to both sides

1.210 = (1+\frac{r}{100} \right ))^{2}

Take square roots of both sides

\sqrt{1.210} = 1+\frac{r}{100}

1.1 = 1+\frac{r}{100}

Subtract 1 from both sides

0.1 = \frac{r}{100}

Multiply both sides by 100

r = 10

10 > 8

<em></em>

<em>Hence, the rate is greater than 8%</em>
