Answer:
D. No, he chose members that were not part of the population
Step-by-step explanation:
A random sample is a sampling technique in which each sample has an equal chance of being chosen. For example, blindly selecting five names from a hat filled with named sheets of paper is a random sample.
Daniel's sample is not random because each sample did not have an equal probability of being chosen. All names he does not recognize are immediately eliminated from being chosen. With this, we can eliminate choices A and B.
Daniel did not chose names from the town he was collecting data for. He chose ones from his own neighborhood. It wasn't in the population he was focusing on.
Therefore, the best answer is D.

Answer:
Dilation
Step-by-step explanation:
Given
Main function: f(x)
Resulting function: 5f(x)
Required
Which transformation exists between both functions
The general explanation is that:
When a function f(x) is multiplied by a constant k, the resulting function g(x) is a dilation of f(x).
Mathematically, if the following relationship exists between f(x) and g(x)
g(x) = k.f(x)
Then g(x) is a dilation of f(x) and k is the constant of proportionality or dilation ratio
In this case:
g(x) = 5f(x)
So, the transformation that answers the question is dilation.
Answer: 9 houses
Step-by-step explanation:
Step 1:
Since 2/3 of the houses were sold last month, 1/3 of them were left.
45 * 1/3 = 15 houses left last month
Step 2:
Since 2/5 of the remaining houses were sold this month, 3/5 of them were left
15 * 3/5 = 9 houses left to be sold
there's your answer hope this helps :)
