Suppose that the amount of a weekly grocery bill of all households in a metropolitan area is distributed with a mean of $140. In a random sample of 49 households selected from this metropolitan area, the sample standard deviation is $35. (Use applet!) a. What statistic is used to analyze this situation? b. Find the statistic and probability that average amount of grocery bill of such a sample will be: i. more than $145, ii. less than $140, iii. between $132 and $148

false

step-by-step explanation:

it is c, trust i got your back lol

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.
