A marketing company will conduct a survey to determine which grocery store is most popular in a city. Which group of people would be considered the best random sample? A. Every 100th household in the city B. Everyone 10th person walking in the mall C. Every 100th person from the telephone book D. Every 10th person outside of one grocery store

Option A

Step-by-step explanation:

Taking a random sample of every 100th household in the city is the best random sample for this survey as every household has to go for grocery shopping at least maybe one or twice a week. And a questionable survey or telephone survey can be used to determined which grocery store they go to and this was be able to estimate the most popular of the grocery stores without bias. The rest options especially b and d if used will produce bias which might tend to lean in favour of the mall wherein they are and not be a representative of the population's opinions.

the answer is. -82562234434584

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.
