Arithmetic sequence
Step-by-step explanation:
A sequence is described as an arithmetic sequence when there is a common difference between the numbers
A sequence is a geometric sequence when there is a common ratio between the numbers
12,10,8
10-12= -2
8-10= -2
10/12= 0.83
8/10= 0.8
Hence the sequence is an arithmetic sequence with a common difference of -2
Answer:
Response Bias
Explanation:
Response bias occurs when participants in a research study have a tendency to reply falsely to research surveys. It is mainly caused by poor survey design, example ambiguous use of likert scale in survey questions. In this case, participants have a pre-recorded response to survey questions which would not accurately represent the population as participant replies are likely to be false.
Answer:
240 ml of 1.5% solution and 360 ml of 4% solution should be used.
Step-by-step explanation:
Since a lab assistant needs to create a 600 mL mixture that is 3% hydrochloric acid, and the assistant has solutions of 1.5% and 4% in supply at the lab, to determine the number of milliliters of the 1.5% solution and the number of milliliters of the 4% solution that must be used, the following calculations must be performed:
50 x 0.015 + 50 x 0.04 = 0.75 + 2 = 2.75
40 x 0.015 + 60 x 0.04 = 0.6 + 2.4 = 3
600 x 0.4 = 240
Therefore, 240 ml of 1.5% solution and 360 ml of 4% solution should be used.
