The answer should be, b = 1
8x³-64x²+x-8 is factored by grouping
8x²(x-8)+1(x-8)
(8x²+1)(x-8) is your answer
-4, -1, 1, 3, 3.9, 3.999,
Answer:
Appendix
Step-by-step explanation:
Answer: 95% confidence interval would be (26.01,29.39).
Step-by-step explanation:
Since we have given that
n = 50
Mean = 27.7
Standard deviation = 6.12
We need to construct 95% confidence interval for the population.
so, z = 1.96
So, it becomes,
Hence, 95% confidence interval would be (26.01,29.39).
