Answer:
Domain = for all x pertaining to reals minus x = 2 and x = -3
Step-by-step explanation:
For this expression to exist, the denominator must be different from zero, so
applying quadratic equation
![\frac{-b+-\sqrt{b^{2}-4ac}}{2a}=\frac{-1+-\sqrt{1^{2}-4.1.-6}}{21}=\\\frac{-1+-\sqrt{1+24}}{2}=\frac{-1+-5}{2}=](https://tex.z-dn.net/?f=%5Cfrac%7B-b%2B-%5Csqrt%7Bb%5E%7B2%7D-4ac%7D%7D%7B2a%7D%3D%5Cfrac%7B-1%2B-%5Csqrt%7B1%5E%7B2%7D-4.1.-6%7D%7D%7B21%7D%3D%5C%5C%5Cfrac%7B-1%2B-%5Csqrt%7B1%2B24%7D%7D%7B2%7D%3D%5Cfrac%7B-1%2B-5%7D%7B2%7D%3D)
x1=(-1+5)/2=2, x2=(-1-5)/2=-3 so, (x-2)(x+3)≠0
Dm=(∀ x ∈ IR - (-3 ∧ 2))
Domain = for all x pertaining to reals minus x = 2 and x = -3
Answer:
Alternate Hypothesis: The true weight of the piglets is greater than or equal to 39 lbs.
Step-by-step explanation:
Hypothesis testing is more like a binary process in which only one (Either Null or Alternate Hypothesis can be true) and we have to infer that whether our Null hypothesis is true or false.
The hypothesis testing involves following 4 general steps:
- State the 2 hypothesis by making sure that they don't overlap with each other
- Develop the analysis plan or any statistical method to know whether the Null hypothesis should be accepted or rejected
- Execute the developed plan and analyze the data
- In the end, after analyzing the data accept or reject the null hypothesis
As in the given question, if a number (X) is less than another number (Y) then it can't be less, equal or greater simultaneously.
