Margin of error, e = Z*SD/Sqrt (N), where N = Sample population
Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96
Therefore,
0.23 = 1.96*1.9/Sqrt (N)
Sqrt (N) = 1.96*1.9/0.23
N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263
Minimum sample size required is 263 students.
Complementary angles are angles who sum to 90 degrees. So, since one angle is 13 degrees, naturally the other must equal 77. Good luck! c:
A clock is 12 hours.
11 hours and 38 minutes is 22 minutes short of being a full 12 hours.
In 12 hours the time would be 5:35 again, so now subtract 22 minutes from the time:
5:35 - 22 minutes = 5:13
In 11 hours and 38 minutes, the time will be 5:13
Answer:
The answer to your question is: 2, 4, 5, 1 , 3
Step-by-step explanation:
The first line is the second
(3x² - 6)² - (3x²)² = 36(1 - x)(1 + 1)
The second line is the forth
9x⁴ - 36x² + 36x² - 9x⁴ = 36(1 - x)(1 + x)
The next line is the fifth
36 - 36x² = 36(1 - x)(1 + x)
The next line is the first
36(1 - x²) = 36(1 - x)(1 + x)
The last line is the third
36(1 - x)(1 + x) = 36(1 - x)(1 + x)
