5/6

Since it is given that it is small, only worry about the small coins.

There are 18 total small coins and 15 of them are gold so 15/18 is the probability or when simplified = 5/6

Azim wants to buy a tablet computer that is priced 180.50 if the sales tax rate on the computer is 8% how many dollars and cents
madreJ [45]

Answer: 98.1%

Explanation:

A 10% sale means that the post-sale price of the item is now 90%, or 0.9 of the original cost of the item. We then apply 9% sales tax by multiplying the 0.9 by 109%, or 1.09. 0.9 * 1.09 = .981, so the total cost of the item is 98.1% of the original pre-sale sticker price.

For percentage problems that do not deal with a specific starting number, it is always helpful to plug in 100 for the starting number. Here, we would then have a post-sale price of 90 dollars, and if we calculate the sales tax for the 90-dollar item it would be 90 * 0.09 = $8.10. THis gives us a total cost of 90 + 8.10 = $98.10, or 98.1% of the original 100-dollar price.

Only ____6%_______% of customers rated the Delta flight Fair or Poor.

b. The online survey questionnaire enabled respondents to explain any aspect of the flight that Failed to meet expectations. Would this be helpful information to a manager looking for ways to improve the overall customer satisfaction on Delta flights? Explain.

Allowing survey respondents to explain their 5-point scale responses would provide helpful information to managers looking for ways to improve customer satisfaction on Delta flights. The ____6______% respondents indicating that the flight failed to meet expectations would have the opportunity to provide detailed information about their expectations.

Step-by-step explanation:

a) Data and Calculations:

                  Rating Frequency     Percent Frequency

Excellent                18                       ____36%___

Very Good            25                       ____50%___

Good                       4                       ____  8%___

Fair                          1                        ____  2%___

Poor                        2                       _____4% __

Total                     50                               100%

b) Percentage Frequencies are obtained as follows:

Excellent = 18/50 * 100 = 36%

Very Good = 25/50 * 100 = 50%

Good = 4/50 * 100 = 8%

Fair = 1/50 * 100 = 2%

Poor = 2/50 * 100 = 4%

c) Good, very good, and excellent = 47/50 * 100 = 94%

d) Fair or Poor rating = 3/50 * 100 = 6%

 

e) Moreover, dissatisfied customers can be sources of great information on the performance of a good or service.  Though, with only 6% of customers giving a dissatisfaction rating with the Delta flights, it is still important to dive deep to unearth the reasons for their dissatisfaction as this may provide valuable information to improve the services.  Usually, this class of customers is the most sincere in most cases, unless their dissatisfaction can be proved to be attitudinal on their own part.

Plz help ASAP! Ineed part C this is due tonight lol (a) How many cups of flour are there in 4 servings? How many cups of flour a
Arte-miy333 [17]

Answer:

1 1/4 cups of flour

Step-by-step explanation:

First find the amount for 1 serving.

So you divide the amount of 1 1/2 or 1.50 by 4

1.50/4=.375

Now do .375*7= 2.625 cups of flour

Now you need to subtract the amount you already have which is 4 cups.

2.625-1.50= 1 1/4 cups of flour is what you need left
