Fast Auto Service provides oil and lube service for cars. It is known that the mean time taken for oil and lube service at this

garage is minutes per car and the standard deviation is minutes. The management wants to promote the business by guaranteeing a maximum waiting time for its customers. If a customer's car is not serviced within that period, the customer will receive a discount on the charges. The company wants to limit this discount to at most of the customers. What should the maximum guaranteed waiting time be

Answer: 19.93 minutes

Explanation:

This is the complete question

Fast Auto Service provides oil and lube service for cars. It is known that the mean time taken for oil and lube service at this garage is 15 minutes per car and the standard deviation is 2.4 minutes. The management wants to promote the business by guaranteeing a maximum waiting time for its customers. If a customer's car is not serviced within that period, the customer will receive a 50% discount on the charges. The company wants to limit this discount to at most 2% of the customers. What should the maximum guaranteed waiting time be? Assume that the times taken for oil and lube service for all cars have a normal distribution

The solution is attached below

The contact between the breccia and the underlying granite is an example of a(n):____.
3241004551 [841]

Correct option is (b): angular unconformity

The contact between the breccia and the underlying granite is an example of angular unconformity

Breccia is a type of  sedimentary rock which is composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix.

In the Italian language ,Breccia word means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, igneous breccia, impact breccia, tectonic breccia and hydrothermal breccia.

Granite is a coarse-grained intrusive igneous rock  which is composed of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground

2. Sunshine Bakery bakes 660 loaves of bread each day and estimates that 10% of the bread will go stale before it is
Alisiya [41]

Answer:

$0.79

Explanation:

The Bakery bakes 660 loaves of bread

The cost of baking one bread= $0.46

The total cost of baking all loaves of bread

= $0.46 x 660

=$303.60

The desired mark up is 55% of cost

=55% of $303.60

=55/100 x $303.60

=0.55 x $303.60

= $166.98

Desired revenues = $166.98 +$303.60

=$470.58

The number of sellable breads= 660 - (10% of 660)

=660-66

=594

Desired income is $470.58; sellable output is 594.

price per bread should be

=$470.58/594

=$0.79222

Price per bread = $0.79

Ziegler Inc. has decided to use the high-low method to estimate the total cost and the fixed and variable cost components of the
telo118 [61]

Answer:

a. $175.50 and $11,060,000

b. $31,242,500

Explanation:

The computation of the fixed cost and the variable cost per unit by using high low method is shown below:

Variable cost per units = (High total cost - low total cost) ÷ (High units produced - low units produced)

= ($32,120,000- $25,100,000) ÷ (120,000 units - 80,000 units)

= $7,020,000 ÷ 40,000 units

= $175.50

Now the fixed cost equal to

= High total cost - (High units produced × Variable cost per unit)

= $32,120,000 - (120,000 units × $175.50)

= $32,120,000 - $21,060,000

= $11,060,000

Now the estimated total cost is would be

= Fixed cost + expected units of production × variable cost per unit

= $11,060,000 + 115,000 units × $175.50

= $11,060,000 + $20,182,500

= $31,242,500

pickupchik [31]

The correct answer is - allows managers to use the normal distribution as the basis for building some control charts.

<u>Explanation:</u>

It is the theorem that allows inference from a random sample. It says that:

• The sample mean will likely be towards the population mean within a margin of error

• The margin of error is a multiple of the standard error, which is the standard deviation divided by the square root of the sample size. The multiple is determined by the degree of statistical confidence you’re looking for, and the normal deviate corresponding to that — 1.65 for 90% confidence, 1.96 for 95% confidence, etc.
