Answer:
(A) Statistical samples are more representative of the population.
Step-by-step explanation:
The following is generally not true about statistical sampling as compared to non statistical sampling:
(A) Statistical samples are more representative of the population.
Statistical sampling refers to a type of statistical study whose sampling method is based on the way we select samples from the population to take part the study/survey.
Answer:
105°
Step-by-step explanation:
Measure of the third angle
= 180° - 18° - 57° (angle sum of triangle)
= 105°
You get the length and you times it by the width giving you the answer
Ok so to find which sides are congruent we need to know their lengths.
To find the length we need the distance formula between two point ->
√(X2-X1)∧2 +(Y2-Y1)∧2
Ok lets find the first side PQ
P(-1,3) Q(2,-1)
X1 Y1 X2 Y2
√(2-(-1)∧2 + (-1-3)∧2 = 5
Now PR
P (-1,3) R (5,3)
X1 Y1 X2 Y2
√(5-(-1))∧2 + (3-3)∧2) = 6
Now the last side QR
Q (2, -1) R (5,3)
X1 Y1 X2 Y2
√(5-2)∧2 + (3-(-1))∧2 = 5
From the above work we see that PQ and QR are congruent becuase they are equal PQ=QR
Also the opposite angles of these sides are congruent. Hope this helps :).
