An article in quality engineering ["designed experiment to stabilize blood glucose levels" (1999–2000, vol. 12, pp. 83–87)] described an experiment to minimize variations in blood glucose levels. the treatment was the exercise time on a nordic track cross-country skier (10 or 20 min). the experiment was blocked for time of day. the data were as follows:

sorry i dont know my friend

answer: huh

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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.
