Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process

Use a square + b square = c square a and b are the short sides of a triangle and c is the largest side of a triangle.
Answer:
y = (-1/5)x + 1
Step-by-step explanation:
The slope of this perpendicular line is the negative reciprocal of the slope of the given line y = 5x + 4: -1/5.
Applying the slope-intercept form of the equation of a line, we get:
2 = (-1/5)(-5) + b, or:
2 = 1 + b
Therefore, b = 1 and the desired equation is:
y = (-1/5)x + 1
