Answer: .1.) 28.8
9.) 150 ft
8.) 630 ft
10.) 5'10"
Step-by-step explanation:. Ratios set up as fractions. 12/25 :x/60
cross multiply. 12 × 60 = 720. Divide by denominator if left side.
720/25 = 28.88
Answer: Inferential.
It is inferential because the survey takes its conclusion(inference) from a sample of the country's population and generalized it on the entire population.
If the results of a survey were claimed to indicate that 7.8% of adults in this country who own digital cameras plan to replace their cameras in the next 12 months. would you say this statement is descriptive or inferential, why?
Step-by-step explanation:
It is inferential because the survey takes its conclusion(inference) from a sample of the country's population and generalized it on the entire population. this claim requires an inference to the population. For example, you might stand in a mall and ask a sample of 200 people if they like shopping at ShopRite. You could make a bar chart of yes or no answers (that would be descriptive statistics) or you could use your research (and inferential statistics) to reason that around 50-75% of the population (all shoppers in malls) like shopping at ShopRite.
