\\ \rm\rightarrowtail s=\dfrac{1.8+2.4+3}{2}

\\ \rm\rightarrowtail s=\dfrac{7.2}{2}=3.6cm

Apply heron s formula

Area:-

\\ \rm\rightarrowtail \sqrt{s(s-a)(s-b)(s-c)}

\\ \rm\rightarrowtail \sqrt{3.6(3.6-1.8)(3.6-3)(3.6-2.4)}

\\ \rm\rightarrowtail \sqrt{3.6(1.8)(0.6)(1.2)}

Len [333]

Answer:

B. 30

Step-by-step explanation:

A line is 180 degrees, so when we have 100, we subtract that from 180 to get the interior angle of 80.

A triangle has a sum of 180, so we just subtract 80 and 70 from 180 to get 30.

Hope this helps

  • 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.
