Consider the class average in an exam in a few different settings. In all cases, assume that we have a large class consisting of equally well prepared students. Think about the assumptions behind the central limit theorem, and choose the most appropriate response under the given description of the different settings Consider the class average in an exam of a fixed difficulty.
A. The class average is approximately norma
B. The class average is not approximately normal because the student scores are strongly dependent
C. The class average is not approximately normal because the student scores are not identically distributed

this might get deleted, sorry. it has to be an actual question. if you really wanted to give someone free points, ask a question like "why does the sky look blue, and the sun is yellow to our eyes? "

step-by-step explanation:

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

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.
