Answer:
23/50
Step-by-step explanation:
4x + 5y + x - 5xy - 3y
5x + 5y - 5xy - 3y
5x + 2y - 5xy
Mean: Add all the numbers and divide by the amount of numbers.
20 + 0 + 7 + 10 + 11 + 0 + 25 + 15 + 1 = 89
89/9 = 9.889 (rounded)
Mean = 9.889 (rounded)
Median: Reorder from least to greatest, and the middle number is the median.
0, 0, 1, 7, 10, 11, 15, 20, 25
The middle number is 7
Median = 7
Mode: The number that shows up the most.
Mode = 0, which shows up one time more than all the other numbers
Range: Subtract the greatest number with least number
25 - 0 = 25
Range = 25
hope this helps
Answer:
The answer to this question is D: None of the above
Step-by-step explanation:
From the example given in the question, this is a bad way of data sampling. The example in the question is a typical Voluntary response sample. In this type of sampling, the researcher creates a request as the case may be in the example through television, and ask for members of a population to join. Thus people then choose to be part of the sample or not. In this type of sampling, the respondents tend to have alike opinion in contrast to the rest of the population. This therefore makes voluntary response sample kind of bias.
