Answer: Simple random sampling
Step-by-step explanation:
Given: A market researcher obtains a list of all streets in a town. She randomly samples 10 street names from the list, and then administers survey questions to every family living on those 10 streets.
Since she randomly samples street names , therefore the type of sampling is simple random sampling.
- A simple random sample is a sample that is a subset of the population the researcher surveyed selected in a way such that all the individuals in the population has an equal chance to be selected.
Answer:
8x + 7y = 30 ( one solution)
8x - 7y = 2
-8x + 7y = -2 ( infinitely many solutions )
8x - 7y = 2
8x - 7y = 2
-8x + 7y = 2 ( zero solutions )
I put them into decimal form. You can order them from greatest to least based off of the decimals

Answer:
The answer to your question is V = 1046.60 u³
Step-by-step explanation:
Data
Volume = ?
radius = 6.3
π = 3.14
Formula
V = (4/3) πr³
Substitution
V = (4/3) (3.14)(6.3)³
Simplification
V = (1.333)(3.14)(250.047)
V = 1046.6017 u³
- Rounding to two decimal places just consider the six and zero
V = 1046.60 u³
