We need to find the center and the radius of
The general circle equation is the following
where
(h,k) is the center and
r is the radius
1. rearrange the equation
2. Add 25 on both sides
3. Factor
Now we have an equation that is very similar to the circle equation, so let's compare them
Center -> (h,k) = (5,-11)
radius -> r = 5
Answer:
Answer is
Step-by-step explanation:
It is 29 in place of 27 . and Its a geometric series with first term 27 and common ratio
and general formula for given sequence is given by
so plugging the value of a and r ,we get

Answer: d. 15.49
Step-by-step explanation:
Given : The random variable K has a geometric distribution with mean 16.
Formula for Mean and standard deviation in geometric distribution:
(1)
(2), where p is the probability of success in each trial.
Since (Given)
Then from (1) ,
Put value of p in (2),
Hence, the standard deviation of random variable K is closest to 15.49.
Therefore , the correct answer is d. 15.49 .
