Answer:
the answer is slope be it give U just the formula
The expressions 100×10 and the more complicated
(100 - 4a)(10 + a)
are calculating annual (expected) revenue. In 100×10 the 100 is the number of decks and the 10 is the price per deck. In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck. So a must be the amount the price increases.
Answer: amount of price increase, last choice

- a) An observation.
- b) A variable.
- c) A population parameter.
- d) A sample statistic.
Given that a survey asked the question, "Do you think a vaccination should be mandatory to enter shopping areas?" to a random sample of 1068 Jordanians, and the results showed that 71.2% responded that vaccination should mandatory, to determine which of the following is an observation, a variable, a sample statistic (value calculated based on the observed sample), or a population parameter, the following statistical reasoning must be performed:
(a) A Jordanian that was asked the question.
-An observation, as the person questioned is part of the study and therefore, it is an individual observation that makes up the trend.
(b) The response of the Jordanian.
-A variable, since it is one of the two possible answers that the survey has.
(c) 71.2%.
-A population parameter, because it represents a specific percentage with respect to the total population.
(d) The percentage of all Jordanians who agreed with the statement that vaccination should be mandatory to enter shopping areas.
-A sample statistic, since it is a statistical element that arises from the survey.

The point among the answer choices which is not in the solution set of the inequality is; (-1, 3).
<h3>Which point is not included in the solution set of the inequality?</h3>
It follows from the task content that the vertex of the two-variable inequality in discuss is; (1, 2).
On this note, it follows that; the two variable inequality described by a parabola opening upward can be written by means of its vertex as;
y >= (x - (1))² + 2
y >= (x-1)² + 2.
By testing points among the answer choices, the point which is not part of the solution set is; (-1,3).
This follows from the fact that; at x=-1;
The value of y is;
y >= (-1-1)² +2
y >= 6
Hence, since the value of y= 3 which is less than, 6, it follows that the point (-1,3) is not in the solution set.
Remarks: The answer choices in the complete question are as follows;
(–1, 3)
(0, 4)
(1, 5)
(2, 4)
