Because angleCBD＋angleBDC＋angleC＝180
so angleCBD＋angleBDC＝180－angleC＝180－82＝98
because BC＝DC
so angleCBD＝angleBDC
so 2 angleCDB＝98
so angleCDB＝49
so y＝29

Considering that the value of 126.07 is valid for the population, it is a parameter.
<h3>What is the difference between a statistic and a parameter?</h3>
- If the measure is defined only for the sample, it is a statistic.
- If the measure can be defined for the population, it is a parameter.
In this problem, the mean blood pressure is calculated for all employees, which means that it is valid for the population, hence it is a parameter.

The picture is really blurry, i can't see the questions
Answer: First Option | 2 x 10^1
Reason: After doing 6.4 divided by 3.2, you get 2, and finally you subtract 10³ by 10². And after that subtraction, you get 10^1, Therefore the answer is the first option.
