The gallup poll uses a procedure called random digit dialing, which creates phone numbers based on a list of all area codes in america in conjunction with the associated number of residential households in each area code. give a possible reason the gallup poll chooses to use random digit dialing instead of picking phone numbers from the phone book.

Random dialing saves time and can cover the region better than the phone book.

Step-by-step explanation:

Not all phone numbers in the region are in the phone book, so dialing through the phone book would be limited, and it would take a long time to dial the numbers on each call. With that Gallup would take longer to complete his work and do a limited job.

On the other hand, random digit dialing would randomly generate phone numbers and select people to participate in Gallup's work much faster, which would allow Gallup to get more calls and work faster and more efficiently.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
