Answer:
C. Sample: listings in a local newspaper and on an Internet sitePopulation: all available apartments near the college
Step-by-step explanation:
The sample is the set of information Greg collects to do his estimation. The sample is necessarily a subset of the population. That is, in this case, the apartments listed in the local newspaper and the internet. He will estimate a mean rent for the sample and, with this result, estimate the population mean rent.
The population is the bigger set available for Greg to do the estimation, and the set he wants to estimate a parameter from (in this case, the mean rent).
In this case, the population is all the apartments near the college.
Answer:
94cm
Step-by-step explanation:
wingspan length
60 meters 70.5 m
----------------- = ----------------
80 cm x
Cross multiply
(60 m)x = (70.5 m)(80 cm)
Solve for x by dividing both sides of equation by 60 m:
x = (70.5 m)(80 cm) / (60 m) = 94 cm
The length of the model is 94 cm.
