2. A large appliance company estimates that the variance of the life of its appliances is 3. You work for a consumer advocacy group and are asked to test the claim at a = 0.05.
You find that the sample of the lives of 27 appliances has a variance of 2.8.

if their are choices you should list them. The givens are pretty specific though.

W = E * I is the answer

E (voltage) = W/I is a more refined answer. <<< answe

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.

the answer is c.
