Salutations!
<span>Are obtuse angles always, sometimes, or never equal to 180°?
Obtuse angles are angles </span>whose measure is greater than 90° and less than 180°. Its not always the case that an obtuse angle should be exact 180 °. So I reckon t would be sometimes, as its not always 180 °.
Hope I helped.
Step-by-step explanation:
f(x)=2x+1
g(x)=2x-7
now,
- f-g(x)=f(x)-g(x)
- 2x+1-2x+7
- 8
(f-g)(x)=8
hope it helps.
Answer:
Step-by-step explanation:
Given that for X the amount of credit card debt for U.S. adults under 35, is
having mean as 8724 dollars.
For this point estimate to be unbiased and most accurate we must ensure that
i) The sample represents the population
ii) Samples are drawn at random
iii) Sample sizes are sufficienly large.
Hence we see that C is not right as college students cannot represent the entire population. Tv poll cannot be said to be random since there may be a significant population who was not aware about this poll. A and B are right but B is better with more sample size.
