Which is a solution to the following system of inequalities?
4x - 3y<9
x+3y>6

А(-2, 1)

B(3, 1)

C(0,4)

D(1,1)

Answers

Answer:

B.

Step-by-step explanation:

its the same as saying..

4x - 3y = 9

x + 3y = 6

add both equation together

5x = 15

i.e X = 3

substitute x= 3 in equation 2

3 + 3y = 6

3y = 3

divide both sides by 3

y = 1

In March of 2018, a survey asked 801 US adults whether they had at least one subscription to a video-streaming service. Of the 801 participants in the survey, 457 indicated they subscribed to at least one video-streaming service. What is the correct 95 percent confidence interval for the proportion of all US adults who would say they subscribe to a video-streaming service?

Answers

Answer:

The 95% confidence interval for the proportion of all US adults who would say they subscribe to a video-streaming service is (0.5362, 0.6048).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Of the 801 participants in the survey, 457 indicated they subscribed to at least one video-streaming service.

This means that [tex]n = 801, \pi = \frac{457}{801} = 0.5705[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5705 - 1.96\sqrt{\frac{0.5705*0.4295}{801}} = 0.5362[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5705 + 1.96\sqrt{\frac{0.5705*0.4295}{801}} = 0.6048[/tex]

The 95% confidence interval for the proportion of all US adults who would say they subscribe to a video-streaming service is (0.5362, 0.6048).

Problem 2

An online retailer advertises the following shipping and handling fees for every order:


Order Amount ($)

0 – 49.99

50 – 75.99

76+

Shipping and Handling ($)

3.95

11.95

5.95


The sales tax in Arizona on online orders is 5.6%. Use this information to answer the following questions.

**Assume that the shipping and handling is added after the sales tax is applied to the order.

Part a)

Using the information above, write an equation that represents the total cost as a function of the order amount in a customer’s “cart”. (Remember: Identify your input and output variables, and use proper notation – I recommend you handwrite your function and add a picture in to this document)



Part b)

Genevieve, who lives in Prescott, has a cart total of $74.50. How much will her total cost be? (Remember: Show all your work for full credit)


Part c)

Rafael, who lives in Tucson, paid $89.20 for his items. How much was his cart total? (Remember: Show all work, and make sure you get all of the answers)

Answers

Answer:

Let the 'cart' total is x and total payment is y.

The sales tax is 5.6% added to the 'cart' amount and then shipping and handling fee added.

Part A

There are three intervals as below and function added accordingly:

0 < x ≤ 49.99      ⇒ y = x + 5.6% + 3.95 = 1.056x + 3.9550 ≤ x ≤ 75.99    ⇒ y = x + 5.6% + 11.95 = 1.056x + 11.95x ≥ 76                  ⇒ y = x + 5.6% + 5.95 = 1.056x + 5.95Part Bx = 74.50, this falls in the second intervaly = 74.50*1.056 + 11.95 = $90.62 (rounded )Part C

y = 89.20, this is close to the number we got in part B and we assume it is same - the middle interval.

89.20 = 1.056x + 11.951.056x = 89.20 - 11.951.056x = 77.25x = 77.25 / 1.056x = 73.15 (rounded )

-----------------------------------------

Note. Shipping and Handling charges seems incorrectly ordered. If so the answers above all should change accordingly.

17 out of 20 lung deserves are curable; what is the percentage of lung diseases that are curable? Yes, but how did you get that answer

Answers

Answer:

85%

Step-by-step explanation:

This problem can be solved by dividing the number of cured cases by the total number of cases (17/20). In order to verify this you can see what number 20 can be multiplied in order to get 100 (5). You can then multiply this by 17 in order to get the number of cured cases out of 100 (the definition of percent)

You need 4 ounces of cooked sausage per person once the raw sausage is cooked its yields50% how many pounds of raw sausage do you need to make to feed 50 people

Answers

Step-by-step explanation:

step 1. 4/.5 x 50 = 400 ounces needed

step 2. 400 ounces (1 lb/16 oz) = 25 lbs.

25 pounds of raw sausages are required to feed 50 people.

Cooked sausage per person = 4 ounces

Amount of cooked sausage required =

(Number of ounce per person × number of persons)

(4 × 50) = 200 ounces of cooked sausage

Yield of sausage once cooked = 50% of raw of sausage

Hence, to obtain 200 ounces of cooked sausage,

Then ; the amount of raw sausage required will be :

(200 ounces) ÷ 50% = 200 ÷ 0.5 = 400 ounces

Converting ounces to pounds :

1 ounce = 0.0625 pounds

400 ounce = (400 × 0.0625) = 25 pounds

Hence, 25 pounds of raw sausages are required
