Aresearcher is interested in the effects of humidity on the eating behavior of rats. a group of 25 rats is housed in a controlled environment and the researcher measures the amount of food consumed by each rat with the humidity set at 20% and again with the humidity set at 80%. for this study a. identify the population, b. identify the sample

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

thus, the first answer choice, y = sec x, is the correct one
