Step-by-step explanation:
P = 6+6+5x-3 + 5x -3 = 10x+6
A = 6(5x-3) = 30x -18
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.

Question 1)
Given the points
Finding the slope between (3, 5) and (3, -6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-6 - 5] / [3 - 3]
= -11 / 0
= undefined or ∞
Thus, the slope of the line = m = undefined.
Note: The undefined slope means the line is vertical.
Question 2)
Given the points
Finding the slope between (-6, 2) and (8, 2)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 2] / [8 - (-6)]
= 0 / 14
= 0
Thus, the slope of the line = m = 0.
Note: The zero slope means the line is horizontal.
