Anita can clean 1/8 portion of the pool in 1 hour

Chao can clean 1/6 portion of the pool in 1 hour

Both of them working together can clean 1/8 + 1/6 = 7/24 portion of the pool in 1 hour

Therefore, it will take both of the working together 1/(7/24) = 24/7 or 3 3/7 hours to clean a typical pool.

Answer:

CASI

Step-by-step explanation:

In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

Sample survey questions are usually read from a computer screen. In a computer-aided personal interview (CAPI), the interviewer reads the questions and enters the responses. In a computer-aided self interview (CASI), the interviewer stands aside and the respondent reads the questions and enters responses. One method almost always shows a higher percent of subjects admitting use of illegal drugs.

This is because they get to interact with a computer rather than a human interviewer.

Someone pls help me thanks
oksano4ka [1.4K]

Answer:

expression: 3(d+35)

simplified expression: 3d + 105

Step-by-step explanation:

The first drone costs d. This means the expression = d

The second drone costs d and an additional $35. Expression = d + 35

The third drone costs 3 times as much as the previous one. Expression = 3(d+35)

To simplify it, you just distribute. Hope this helps :)
