Louise just received word that she scored 87% on a geometry test. Louise is also in an advanced calculus course. Is Louise's mark on her geometry test an accurate predictor of how well students in the geometry class will perform on the same test?

Not at all, we cannot say because we do not have enough data.

Step-by-step explanation:

The fact is we only have the score of one individual out of a population. This sample is not enough to aid in drawing a conclusion. Basically, the more samples we get from the population, the closer to accuracy we get. Therefore, we will need more scores from the geometry test to predict more accurately than with just the score of Louise.

Moreover, Louise is taking an advanced calculus course, so we can infer that she is quite apt when it comes to Mathematics.

Other students may have performed well and they also may not have, but we can not tell with just the score of an individual.

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.
