Answer:
No
Step-by-step explanation:
Do they have common factors?
No which is why they are not able to be simplified further
so no
Answer:
We accept H₀ with the information we have, we can say level of ozone is under the major limit
Step-by-step explanation:
Normal Distribution
population mean = μ₀ = 7.5 ppm
Sample size n = 16 df = n - 1 df = 15
Sample mean = μ = 7.8 ppm
Sample standard deviation = s = 0.8
We want to find out if ozono level, is above normal level that is bigger than 7.5
1.- Hypothesis Test
null hypothesis H₀ μ₀ = 7.5
alternative hypothesis Hₐ μ₀ > 7.5
2.-Significance level α = 0.01 we will develop one tail-test (right)
then for df = 15 and α = 0,01 from t -student table we get
t(c) = 2.624
3.-Compute t(s)
t(s) = ( μ - μ₀ ) / s /√n ⇒ t(s) = ( 7.8 - 7.5 )*4/0.8
t(s) = 0.3*4/0.8
t(s) = 1.5
4.-Compare t(s) and t(c)
t(s) < t(c) 1.5 < 2.64
Then t(s) is inside the acceptance region. We accept H₀

Answer:
(3x + 2)(9x^2 - 6x + 4)
Step-by-step explanation:
Simple Question.
27x^3 + 8 = (3x)^3 + (2)^3
You can now apply the sum of the cubes formula:
x^3 + y^3 = (x + y)(x^2 - xy + y^2),
(3x)^3 + (2)^3 = (3x + 2)(3^2x^2 - 2*3x + 2^2)
= (3x + 2)(9x^2 - 6x + 4)
Solution: (3x + 2)(9x^2 - 6x + 4)
