Tan ( a + b ) = [ tan a + tan b ] / [ 1 - (tan a)*(tan b) ];
let be a = 2x and b = x;
=> tan 3x = [ tan 2x + tan x ] / [ 1 - (tan 2x)*(tan x) ] => (tan 3x)*[ 1 - (tan 2x)*(tan x) ] =
tan 2x + tan x => tan3x - tan 3xtan 2xtanx = tan 2x + tan x => <span> tan 3x−tan 2x−tanx = tan 3xtan 2xtanx.</span><span />
They are not inverse functions of one another. For f(x) and g(x) to be inverses of each other, f(g(x)) = x. In this case, pi(x+2/pi)-2 = pi* x, which is not x.
Answer:
Yes, the given analysis involves a statistical test. Population parameter of interest = '% of community people living in mobile homes' (MH)
- H0 : MH = 0.09
- H1 : MH > 0.09
Step-by-step explanation:
Hypothesis testing is a statistical test, of testing an assumption (statement) about population parameter.
Null Hypothesis [H0] is a neutral statement of 'no difference' about a population parameter; stating variable is no different than its mean.
Alternate hypothesis [H1] is the 'specific difference' stating hypothesis about a population parameter; contrary to the null hypothesis.
To determine if there is evidence for the claim that the percentage of people in the community living in a mobile home is greater than 9% :
This analysis can be done by using statistical test : one sided 't' test. The population parameter of interest would be '% of community people living in mobile homes' (MH)
- H0 : MH = 9% → MH = 0.09
- H1 : MH > 9% → MH > 0.09
