C. The statement is not correct. Samples should be chosen randomly to ensure that each individual in the population has about the same probability of being chosen.
Step-by-step explanation:
Random sampling ensures that all the individuals in a population has a chance to be chosen to participate. This method also ensures that they get an unbiased result. Even with a large sample size, the selection of the sample is integral to ensure that the researcher gets an unbiased representation of the group.
Answer:
D The solution is 35, which represents the number of miles she runs each week.
Step-by-step explanation:
Given that Gisele trains 7 days a week, the total of miles she cycles and runs in a week can be divided by 7, or multiplied by 1/7 to find her daily average. Her total number of miles ran for the week combined with her cycling miles multiplied by 1/7 would average 20 miles daily. Since the run is the same each day, using the equation:
1/7(105 + r) = 20 will give the value of 'r' in the number of miles ran per week
105 + r = 140 (multiply both sides by '7')
r = 35 (subtract '105' from both sides)
