The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.
Answer:
r = 24 ft
Step-by-step explanation:
Circumference is given by
C = 2 * pi *r
We know that C = 48 pi
48 pi = 2 * pi * r
Divide each side by pi
48 pi /pi= 2 * pi * r/pi
48 = 2 r
Divide each side by 2
48/2 = 2r/2
24 = r
D. 5root3
x = 15/root3 = 15root3/3 = 5root3
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.
hope this helps :)
