List the descriptors used to interpret a scatter plot and provide a brief explanation for each

POSITIVE- a general increasing trend where the plotted points go in the general direction from bottom left to top right.

NEGATIVE- a general decreasing trend starting from top left decreasing to the bottom right.

NO CORRELATION- points are scattered everywhere and no trend can be seen

you can also have strong positive and negative depends how clear the trend is and if the direction is extremely clear.

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.
