Answer:
Step-by-step explanation:
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
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

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?
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)
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 AThere 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 Cy = 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.5 – 4|1 + 2x| = -3

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)
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
A car travels 208 miles in 3 hours and 15 minutes. How many miles does it travel per hour?
Answer:
64 miles
Step-by-step explanation:
3 hours and 15 minutes = 3.25 hours (since 15 minutes is a quarter of an hour)
so 208 miles in 3.25 hours can be written as
208 miles / 3.25 hrs = 208/3.25 miles/hrs (or miles per hour)
=64 miles per hour

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
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)
