Scientists take scientific measurements carefully in order to ensure their reliability and validity. which of the following is an example of measurement bias in scientific measurement?
a. a scale that reads zero when nothing is on it
b. a stopwatch that stops immediately when the stop button is clicked
c. a balance that always reads .01 g
d. measuring your height in your bare feet

the correct answer is option C my guy

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
