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.
Answer:
Solution given:
letA=(10,-4)
B=(-2,-4)
centre[C](h,k)=
radius=
units
we have
Equation of a circle is;
(x-h)²+(y-k)²=r²
(x-4)²+(y+4)²=36
or.
x²-8x+16+y²+8y+16=36
x²-8x+8y+y²=36-32
x²-8x+8y+y²=4
