Answer and Explanation:

The computation is shown below:

b. The upper specification limit is

= 4 + 0.08

= 4.080 mm

c. The Lower specification limit is

= 4 - 0.08

= 3.920 mm

d. The process capability index is

= min ((Upper specification limit - Mean) ÷ (3 × Standard deviation)), ((Mean - Lower specification limit)÷ (3 × Standard deviation))

= min (0.08 ÷ (3 × 0.02)), (0.08 ÷ (3 × 0.02))

= min (1.333, 1.333)

So it would be 1.333

e. Upper specification = 4.08 mm

Mean line = 4.0 mm

Now,

The upper specification lies at a distance = Upper specification - Mean line

= 4.08 mm - 4.0 mm

= 0.08 mm

upper specification =Upper specification lies ÷ One standard deviation

= 0.08 mm ÷ 0.02 mm

= 4 mm which is standard deviations from the mean

Mary Smith took a car loan of $25,000 to pay back in 48 monthly installments at an interest rate of 8%. Compute the loan balance
Naya [18.7K]

Answer:

$9,233.

Explanation:

The balance of the loan after the 32th payment can be determined after constructing a loan amortization schedule for this car loan. To construct the amortization schedule, we need to first calculate the monthly instalments (PMT) as this is the missing parameter for our time value of money.

I am using a financial calculator here to calculate the monthly instalment :

PV = $25,000

P/YR = 12

I = 8%

N = 48 (years)

FV = $0

PMT = ?

Therefore, the monthly instalment PMT is  $610.32.

But, we need the balance immediately after the 32th payment, so we construct an amortization schedule - now that we have all the parameters.

On a financial calculator enter 1 INPUT 32, SHIFT AMORT.

Pressing the equal sign gives the principle then interest and finally the balance of this loan after the 32th payment. The balance you should get if you follow this procedure carefully is $9,233.

Hard qualitative criteria

Explanation:

The qualitative requirements in marketing begin with a quick-term target, in which the qualitative standards: architecture, online distribution platforms, customer satisfaction and e-loyalty are also included.

Briefly, the process of gathering large amounts of data by polls, surveys and voting techniques relates to quantitative market research. Qualitative market research, alternatively, involves trying to determine customer motivation through close analysis ––typically in a tiny group or face-to-face encounter.
