Answer:
x²+17x+66
Step-by-step explanation:
Step 1: x×(x+6)+11(x+6)
Step 2: x²+6x+11(x+6)
Step 3: x²+6x+11x+66
Answer: x²+17x66
Answer with explanation:
In Inferential Statistics,maximum number of times data is read to find or deduce the Correct Information about the data set ,with the help of Different Measures of variation or for the particular kind of information.And then the old Hypothesis about the Data set is being tasted and if found incorrect, remedial measures are taken, that is it can be altered and Correct Hypothesis is Structured.
→Data Set is about : Average life of Different Bulbs
→Measure of Variation : Mean
→Phase of inferential statistics: Data Analysis
Data Analysis ,that is with the help of mean,average life of bulb-lifetime data is gathered.
Answer:
a) See answer below.
b) Equal chance of being selected.
c) Accuracy
Step-by-step explanation:
a. How might the strategy of leaving out cell phones affect the goal of obtaining a random sample of voters of consumers?
This strategy might affect the goal of obtaining a random sample by not choosing the sample from all the population of the USA. People who don't have a landline an only have a cell phone will have zero chance of being selected and therefore the polls will not be accurate.
b. Which criterion of random sampling is most likely to be violated by the problems you identified in part (a)?
Equal chance of being selected, since the people who only have cell phones will not be selected for the poll, this criterion of random sampling will be violated.
c. Which attribute of estimated consumer preference is most affected by the problem you identified in (a)
Accuracy. The definition of accuracy is how close a value really is to its true value.
By not selecting the sample from all the population, the results of the poll will likely be biased and therefore they might not be close to the actual preferences of consumers or voters.
I think that # 15 is 10,000 + 400 + 50 + 6 and #16 is 100,000 + 80,000 + 70 + 5. It's really simple to figure out; just find the number in the place value and, for how many digits after it, substitute zeros (if that makes sense).
Hope this helps!
