A television station is interested in predicting whether or not voters are in favor of an increase in the state sales tax. It asks its viewers to phone in and indicate whether they support or are opposed to an increase in the state sales tax in order to generate additional revenue for education. Of the 2633 viewers who phone in, 1474 (55.98%) are opposed to the increase. The sample obtained is ____(A) all people who will vote on the sales tax increase on the data of the vote.(B) the 1474 viewers were opposed to the increase.(C) the 2633 viewers who phoned in.(D) all regular viewers of the television station who own a phone and have participated in similar phone surveys in the past.

Answer:
Every 10th product in the line is selected
Step-by-step explanation:
Convenience sampling also available sampling, or nearest in reach sampling.
it is a type of non-probability sampling that involves the sample being drawn from a population that is in reach or that is easily at hand.
example. A questionnaire being distributed to people met in a mall.
for the manufacturing company in question, the first 10 product in line were the first set of product the machine will produce (at hand).
it is normally use to test run the operation of the machine.
Final answer:
Convenience sampling in manufacturing is best described as selecting every 10th product in the line for testing. It is a simple, quick, and cost-effective way to identify potential issues.
Explanation:
In the context of manufacturing, convenience sampling represents a type of sampling where samples are chosen because they are readily available or easy to obtain. In the provided choice list, the best description of convenience sampling is 'Every 10th product in the line is selected'. This method is chosen for its simplicity and speed. While it may not provide a comprehensive result since it won't cover all the various different scenarios, it is a cost-effective and time-efficient way of identifying potential issues in machine operations.

Answer:
Range : [-6, ∞)
Step-by-step explanation:
Domain of any function on a graph is represented by the x-values (input values).
Similarly, Range of function is represented by the y-values or output values of the function on a graph.
Therefore, domain of the given absolute function will be (-∞, ∞) Or set of all real numbers.
Range of the function → [-6, ∞) Or {y | y ≥ -6}

(b) Loss of $4
Step-by-step explanation:
C(q) represents Cost of producing q units.
R(q) represents Revenue generated from q units.
P(q) represents Total Profit made from producing q units.
Marginal analysis is concerned with estimating the effect on quantities such as cost, revenue, and profit when the level of production is changed by a unit amount. For example, if C(q) is the cost of producing q units of a certain commodity, then the marginal cost, MC(q), is the additional cost of producing one more unit and is given by the difference
MC(q) = C(q + 1) − C(q).
Using the estimation
C'(q)≈[TeX]\frac{C(q+1)-C(q)}{(q+1)-q}[/TeX]=C(q+1)-C(q)
We find out that MC(q)=C'(q)
We can therefore compute the marginal cost by the derivative C'(q).
This also holds for Revenue, R(q) and Profit, P(q).
(a) If C'(50)=75 and R'(50)=88
51st item.
P'(50)=R'(50)-C'(50)
=88-75=$13
The profit earned from the 51st item will be approximately $13.
(b) If C'(90)=71 and R'(90)=67, approximately how much profit is earned by the 91st item.
P'(90)=R'(90)-C'(90)
=67-71= -$4
The profit earned from the 91 st item will be approximately -$4.
There was a loss of $4.

Answers
Step-by-step explanation:
Use shifts to write sine and cosine in terms of each other.
a) sin (x – 5°) = cos (35°)
sin (x – 5°) = sin (90° – 35°)
sin (x – 5°) = sin (55°)
x – 5° = 55°
x = 60°
b) sin (2x – 17°) = cos (x – 4°)
sin (2x – 17°) = sin (90° – (x – 4°))
sin (2x – 17°) = sin (90° – x + 4°)
sin (2x – 17°) = sin (94° – x)
2x – 17° = 94° – x
3x = 111°
x = 37°
c) sin (x) = cos (x)
sin (x) = sin (90° – x)
x = 90° – x
2x = 90°
x = 45°
