In a survey of 850 students in a school, 90% reported having pets at home. If the margin of error is ±3.4%, what is the interval that is likely to contain the exact percent of all people who have pets at home? a) between 90% and 93.4%
b)between 86.6% and 93.4
c) between 86.6% and 90%
d) between 3.4% and 90%

there are no figures how am i supposed to answer this question

step-by-step explanation:

step-by-step explanation:

if x = 2 you have to find x to finish the problem

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.
