Answer:
We conclude that a researcher used simple random sample.
Step-by-step explanation:
We know that select a sample of five children from a class of 30, a researcher puts each child’s name on a slip of paper, then shuffles the papers in a hat and randomly picks five names.
We conclude that a researcher used simple random sample.
Because every children has an equal chance of being included in the sample.
By just looking at ur whole numbers...12 + 3 + 5 = 20...and thats not even counting ur decimals..so by adding ur decimals, u know that it will be over 20.
You want log √(9/25). Recognizing that √9 = 3 and that √25 = 5, we get
log 3/5, which by rules of logs comes out to log 3 - log 5.
To four decimal places:
log 3 - log 5 = 0.4771 - 0.6990, or -0.2218.
Answer:
10 tickets = 30$
20 = 60$
30 = 90$
40 = 120$
50 = 150$
Depend on the comparison. if u want to see greater or less then use = < > or the difrent subtract . add if finding the total.
