suppelementary angles are angles that add to 180
remember that a straight line is 180 degrees so some angles that are supplementary are 1 and 2, 5 and 6, 1 and 5, 6 and 2, 3 and 7, 4 and 8, 7 and 8, 3 and 4
vertical angles are across from each other when 2 lines cross, they are like 5 and 2, 6 and 1, 7 and 4, 8 and 3
Answer:
2
x
Step-by-step explanation:
The diagonal divides the square into 2 right angles with legs s and hypotenuse x
Using Pythagoras' identity on one of the right triangles, then
s² + s² = x²
2s² = x² ( divide both sides by 2 )
s² = 
( take the square root of both sides )
s = 
= 
Thus
perimeter = 4s = 4 × = 
Multiply numerator/ denominator by
perimeter = 
= 2 x
x = 6
Explanation:
use the pythagorean theorem which is <u>a^2 + b^2 = c^2</u>. 8 goes in either the a or b position and 10 is the longest side so it will go in the c position.
Answer:
Non-response bias
Step-by-step explanation:
Selection bias in a survey occurs when individuals are selected in a disproportionate way such that the samples obtained do not represent the true population to be studied or interviewed. An example of a selection bias that can occur from Random-digit dialing is the non-response bias.
Participants who are to be selected for surveys must be eligible or suitable for the purpose of the experiment. If the survey is trying to measure the effect of stress on parents, there is a possibility that through random-digit dialing, homes might be called at times when parents are on a work trip. This inability to get the response of eligible subjects for the survey is a form of selection bias.
