Answer:
An appropriate method is to generate a simple random sample of all single-family homes in the city or a stratified random sample by taking a simple random sample from each of the ten district neighborhoods.
Step-by-step explanation:
A sampling procedure that gives an assurance that each item or person in the population has the same chance of being included in the sample is known as a simple random sample.
A sample obtained by dividing the population elements into strata and then selecting a random sample directly and independently from each stratum is known as a stratified random sampling.
Simple random or stratified random sample may be used by the real estate appraiser to predict appraised value from various characteristics of size, age, number bath rooms etc.
With respect to the simple random sample method, the real estate appraiser needs to obtain a random sample of single family homes and then study or predict the required characteristics.
Whereas, for the stratified random sampling method, he has to consider each of the given neighborhood districts (10) as stratums and generate a simple random sample from each of the stratum. Then, from the generated sample he would be able to study or predict the required characteristics.
The population given in this case study is finite and identifiable. Thus, it is enumerative.

In your shoes I'd be doing all I could to solve these problems myself. What would happen if no one helped you with these?
We are told that the base of the ladder is 3 ft from the building foundation. Thus,
opp side 3 ft
sin 49 deg = ------------ = --------
hyp hyp
then hyp = (3 ft) / (sin 49 deg) = (3 ft) / (0.755) = 3.98 feet Rounding this off, we get (ladder length) = 4.0 ft. (ans).
Now that we know the length of the hyp (length of the ladder), we can find
the height of the top of the ladder off the ground using the cosine function:
(3.98 ft)(cos 49 ) = height = (3.98 ft)(0.656) = 2.6 ft
Answer:
its divided by 3
Step-by-step explanation:
so 3 is the answer
