To find the terms, multiply by .5
5, .5 times 5 = 2.5, .5 times 2.5 = 1.25, .5 times 1.25 = .625, .5 times .625 = .3125
Answer:
Yes
Step-by-step explanation:
Remember in order for the rates to be proportional it has to have a constant rate of change and it has to go through the origin if graphed
For one this has a constant rate of change which is 3 dollars per 25 messages
Now we just have to find out if it would go through the origin (0,0)
To do so we subtract 3 dollars and then 25 messages
6-3=3
50 - 25 =25
then again 25-25=0
3-3=0
concluding that (0,0) is a solution
Thus meaning that this is a proportional relationship
Answer:
unbiased sample values
Step-by-step explanation:
Unbiased sampling involves eliminating any form of bias in the method of selection of participants in a study in order to draw a conclusion about the population.
Paul had introduced bias in the sampling that out to look at the number of hours a day the typical student studies by introducing the variable of studying during the final exam period.
Most likely all student will study during the final exam period. This will not truly represent the study pattern of the sample population and equal chance of selection of study hours of the students. Hence paul had violated the requirement of unbiased sample values for probability sampling by not doing a random selection or systematic random selection
