Answer:

Option B - 90 students at random during lunch

Step-by-step

An unbiased sample is defined as:

A sample is an unbiased sample if every individual or the element in the population has an equal chance of being selected.

Based on this, we can eliminate:

Option A) - It prevents non-eighth-graders of the school from being represented.

Option C) - Students in a hallway might take a particular class together/may be of the same grade. This gives them an unfair advantage.

Option D) - All students who are not in chorus are not represented in this set.

Solution 1 :-

Given expression ,

$\implies 13^{\frac{3}{4}}$

We know that, $a^{\frac{m}{n}} = \sqrt[n]{a^m}$

Therefore , this can be written as ,

$\implies \sqrt[4]{13^3}$

Solution 2:-

Given expression ,

$\implies \sqrt[3]{24^{10}}$

We know that, $a^{\frac{m}{n}} = \sqrt[n]{a^m}$

Therefore, this can be written as ,

$\implies 24^{\frac{10}{3}}$

Answer:

Total area = 237.09 cm²

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Field book of an agricultural land is given in the figure. It is divided into 4 plots. Plot I is a right triangle, plot II is an equilateral triangle, plot III is a rectangle and plot IV is a trapezium, Find the area of each plot and the total area of the field. ( use √3 =1.73)

From the figure attached,

Area of the right triangle I = $\frac{1}{2}(\text{Base})\times (\text{Height})$
