Answer:
4(a-2)+a=4a-2 No solution
Step-by-step explanation:
This would never be true. Try plugging in <em>a</em> as 1.
4(1-2)+1 isn't equal to 4(1)-2.
- 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.

There is no postulate that can shows that these triangles are congruent, SSA is not usable and does not show congruence.
Clearly, wether we're talking about tiles, plants, pages, e-mails, friend or files, the math won't change! :)
Percentages are just special fractions, since they have denominator 100. So, for example, 64% of 75 is given by

So, you divide the number by 100 and then you multiply by the percentage you want. As a last example, 20% of 70 is

And so on with all the others
