irakobra [83]

Answer:

This is a response bias

Step-by-step explanation:

Response bias is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions. These biases are prevalent in research involving participant self-report, such as structured interviews or surveys. Response biases can have a large impact on the validity of questionnaires or surveys.

This is exactly what happens here in the excercise, the result of the poll do not match the vote count, both results do not match, therefore, we can see that a lot of people lied in the poll or simply did not answer it very well.

What is the length of line segment BC?​
Nezavi [6.7K]

Answer:

d. 10.53 units

Step-by-step explanation:

This question could be answered by Pythagoras Theorem which is :

a^{2} +b^{2} =c^{2} In every triangle c is always the hypotenuse ( which is the longest line in the triangle/ the line where the right angle sign is pointing to )

a or b could be either one of the other lines of the triangle it doesn't matter.

First you find AC which is simply by adding the two 5.2 values which is 10.4 units.

BC can be written as b in our Pythagoras equation and if you first substitute it you will have:

10.4^{2} + b^{2} = 14.8^{2}

To find b you rearrange everything to the other side except b

b=\sqrt{14.8^{2}-10.4^{2}  }

And if you type that in the calculator you get

BC= 10.53 units (2 decimal place)

Hope it is right, and ask any questions if unsure :)))
