Suppose​ that, when taking a random sample of three​ students' GPAs, you get a sample mean of 3.90. This sample mean is far high
vesna_86 [32]

Answer:

Your sample most likely is biased, but simply getting a high number does not 100 percent mean your answer was biased. It could be a pure coincidence that you picked students with high GPAs. However, it is likely that your answer is biased. You may have sampled kids that are in advanced classes. You may have sampled students that were in some sort of honors club. You may have sampled students that were all hanging out in the library, a place that most people come to study and prepare for classes. So again, while your higher than normal answer could have been a coincidence, you most likely had a biased sample.

Explain why triangle pqs is isosceles
barxatty [35]

Answer    

By using the exterior angle property

The measure of exterior angle is equal to the sum of two opposite interior angles.  

In ∠QSR is exterior angle.

∠SPQ and ∠SQP are the opposite  interior angle of the exterior angle ∠QSR .

Thus

∠QSR  =  ∠SPQ + ∠SQP

As given in the diagram

∠QSR  =  2x  , ∠SQP = x

Put in the above

2x = x + ∠SQP

∠SQP = 2x - x

∠SQP = x

Thus

∠SPQ =  ∠SQP = x

By using the property

if two angles are equal in a triangle than their opposite sides are also equal .

Thus

PS = SQ

Two sides of triangle are equal .

therefore Δ PQS is a isosceles triangle .

mark the statements that are true. A. an angle that measure 170 degrees is an obtuse angle B. an angle that measures 95 degrees
luda_lava [24]

Answer:

hello and thank u for asking questions

the correct answers are...

A. is correct because an obtuse angle is an angle that measures over 90°

B. is incorrect because the acute angle is less than 90°

C. is correct because a reflex is "Reflex angles are angles measuring greater than 180 degrees and less than 360 degrees. The measure of a reflex angle is added to an acute or obtuse angle to make a full 360 degree circle"

D. is incorrect because if it is less than 2 but greater than 4 that does not make any sence

hopes this help pls mark brainiest and have a great and wonderful rest of your day
