Recently, a random sample of 25–34 year olds was asked, "How much do you currently have in savings, not including retirement savings?" The following data represent the responses to the survey. Approximate the mean and standard deviation amount of savings. The sample mean amount of savings is $ ?

y=mx+b is the final answer!   : )

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.

maya’s expression will generate the wrong sum because she violated the commutative property.
