What is the question?????
Answer:5,700
because:
380 time 15 is equal to:
5,700
770:5 or 154:1
154 km per hour
Answer:
Try 300
Step-by-step explanation:
Because one full order would be 20 dollars and 20 times 15 equals 300
Answer:
Decrease the sample size.
Step-by-step explanation:
Margin of error is:
ME = CV × √(σ / n)
where σ is the population standard deviation, or:
ME = CV × √(p (1 − p) / n)
where p is the proportion.
In each case, the margin of error is directly proportional to the critical value, and inversely proportional to √n.
Lowering the confidence level will lower the critical value, which will decrease the margin of error. Decreasing the sample size will increase the margin of error.
