Which of the following would most likely be viewed as an example of primary data? you search the internet for information about a particular topic you collect data using a questionnaire you design and send out online you use census data collected by the government you buy data on consumers from a marketing research company

You collect data using a questionnaire you design and send out online

Step-by-step explanation:

Primary data is the process of collecting data directly from the original source rather than from investigations/ researches done by other people.

1. Search the internet for information about a  topic is not an example of primary data because internet is full of data gathered by many different people.

2. You collect data using a questionnaire you design and send out online: This would be an example of primary data because you are designing the questionnaire for your research and will send it to the people you need.

3. You use census data collected by the government: This is not primary data because the data was first collected by the government.

4. You buy data on consumers from a marketing research company: Again, this data was collected by another company so it's not an example of primary data.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
