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 :)
Answer:
43 15/22 degrees
Step-by-step explanation:
The three angles add to 180 degrees
7x+6 +10x-8 + 5x+3 = 180
Combine like terms
22x +1 = 180
Subtract 1 from each side
22x +1-1 =180-1
22x = 179
Divide each side by 22
22x/22 = 179 /22
x =179/22
The smallest angle is
5x+3
5(179/22) +3
895/22 +3
40 15/22 +3
43 15/22 degrees
Answer:
=33/40
Step-by-step explanation:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
118÷53
Applying the fractions formula for division,
=11×38×5
=33/40
=33/40
2(4*3) + 5.7*3 + 2(5.7*4)= 86.7 mm^2 (i could be wrong)
