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
Answer:
It would be x < 4.
Step-by-step explanation:
Your answer would be x < 4. This is because with this inequality, x would always be less than 4.
Know This:
<em>If it was less than or equal to 4 feet, it would of been x ≤ 4.</em>
Tips:
<em>Less or equal to: x ≤ 4</em>
<em>Less than: x < 4</em>
<em>More or equal to: x ≥ 4</em>
<em>More than: x > 4</em>
<span>The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus:
x^2 - 36 = 5x
x^2 - 5x - 36 = 0
x^2 + 4x - 9x - 36 = 0
x(x + 4) - 9(x + 4) = 0
(x - 9)(x + 4) = 0
x - 9 = 0 or x + 4 = 0
x = 9 or x = -4
Therefore, the positive solution of x^2 - 36 = 5x? is 9.</span>
Answer:
x=any real number
Step-by-step explanation:
5 ( 1 + X) = 5x + 5
5x+5=5x+5
