A researcher wishes to design a fully blocked experiment with groups of subjects representing every possible combination of 1 explanatory variable (control versus treatment) and 4 other variables (male versus female, old versus young, healthy versus ill, and normal weight versus overweight) for a total of 5 variables. How many blocks will be in her experiment ?

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
