Charles wants to find out if the students in foreign language classes spend more time in class speaking in English or in the for

eign
language they are studying. Charles first gets class lists of all students taking foreign language classes. He then chooses 10
students from each different language class to survey. Which best explains why the sample he chose may not be a
representative sample?
The sample size is not large enough to represent the population.
The sample was not chosen at random.
The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.
The way the sample was chosen does not sample students from each different language class.​

Nata [24]

Answer:

(sqrt(x) +1)(sqrt(x)-2)

Step-by-step explanation:

x - 2 \sqrt{x}  +  \sqrt{x}  - 2 \\  \sqrt{x} ( \sqrt{x}  - 2) + 1( \sqrt{x}  - 2 ) \\ ( \sqrt{x}  + 1)( \sqrt{x}  - 2)

Straight angles Are extremely important in geometry. When two lines intersect , they form multiple angles. In the diagram below,
rusak2 [61]
When two straight lines intersect, the vertical opposite angles intersect. the other two angles are also equal. Let the known angle be x, then the other two adjacent angles are obtained subtracting twice of x from 360 and dividing the result by 2.

Therefore, the table can by filled as follows:

Row 1:

Given <GEF = 120°

<FEM is adjacent to <GEF, thus
\angle FEM= \frac{360-2(120)}{2} \\ \\ = \frac{360-240}{2} = \frac{120}{2} =60^o

<MEH is vertically opposite to <GEF and thus is equal to <GEF. Thus <MEH = 120°

<HEG is vertically opposite to <FEM and thus is equal to <FEM. Thus <HEG = 60°.



Row 2:

Given <MEH = 150°

<MEH is vertically opposite to <GEF and thus is equal to <GEF. Thus <GEF = 150°

<FEM is adjacent to <GEF, thus
\angle GEF= \frac{360-2(25)}{2} \\ \\ = \frac{360-50}{2} = \frac{310}{2} =155^o

<HEG is vertically opposite to <FEM and thus is equal to <FEM. Thus <HEG = 30°.



Row 3:

Given that <FEM = 25°

<FEM is adjacent to <GEF, thus
\angle GEF= \frac{360-2(25)}{2} \\ \\ = \frac{360-50}{2} = \frac{310}{2} =155^o

<MEH is vertically opposite to <GEF and thus is equal to <GEF. Thus <GEF = 155°

<HEG is vertically opposite to <FEM and thus is equal to <FEM. Thus <HEG = 25°.



Row 4:

Given that <HEG = 45°

<HEG is adjacent to <GEF, thus
\angle GEF= \frac{360-2(45)}{2} \\ \\ = \frac{360-90}{2} = \frac{270}{2} =135^o

<HEG is vertically opposite to <FEM and thus is equal to <FEM. Thus <FEM = 45°

<MEH is vertically opposite to <GEF and thus is equal to <GEF. Thus <GEF = 135°.
