Answer:
The correct answer is A
Step-by-step explanation:
The reasoning is that I just got it correct on Edgenuity :p
Judging on the question I realized to find the probability of finding a white paperclip would be a fraction.
The numerator of the fraction should be (9) white paperclips. The denominator of the fraction should be (20) the TOTAL amount of paperclips (white+green+red).
The fraction should be 9/20. or 45%
Answer:
Please see the attached pictures for the full solution.
Step-by-step explanation:
the lowest common denominator (LCD) is the lowest common multiple (LCM) of the denominator numbers (the ones at the bottom of the fractions).
finding the LCM of 9 and 12 using the prime factor method :
9 = 3×3
12 = 2×2×3
the LCM is the combination of the longest chains per prime factor. which means we have 2×2 and 3×3 as longest chains for 2 and 3.
LCD = LCM = 2×2×3×3 = 36
2/9 turns into x/36 by multiplying by 4/4 :
2/9 × 4/4 = 8/36
5/12 turns into x/36 by multiplying by 3/3 :
5/12 × 3/3 = 15/36
so, the third answer option is correct.
Using margin of error, it is found that increasing the sample size results in a smaller sampling error.
The equation for the <em>margin of error</em> is given by:
In which:
- c is the critical value according to the distribution used.
- s is the standard deviation, either of the sample or of the population.
From the equation, it can be noted that the margin of error is inversely proportional to the square root of the sample size, hence, increasing the sample size results in a smaller sampling error.
