The random variable K has a geometric distribution with mean 16. Which of the following is closest to the standard deviation of
sdas [7]

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:

\mu=\dfrac{1}{p}    (1)

\sigma=\dfrac{\sqrt{1-p}}{p}   (2), where p is the probability of success in each trial.

Since \mu=16  (Given)

Then from (1) ,

\dfrac{1}{p}=16\\\Rightarrow\ p=\dfrac{1}{16}=0.0625

Put value of p in (2),

\sigma=\dfrac{\sqrt{1-0.0625}}{0.0625}=\dfrac{\sqrt{0.9375}}{0.0625}  

=\dfrac{0.968245836552}{0.0625}

=15.4919333848\approx15.49

Hence, the standard deviation of random variable K is closest to 15.49.

Therefore , the correct answer is d. 15.49 .

Consider the situations in the table below ^^^
netineya [11]

Answer:

  ACBD

Step-by-step explanation:

Increases, gains, earnings, upward motion are all represented by positive numbers. Decreases, losses, spending, downward motion are all represented by negative numbers. Here are the sums:

A: -33.57 +14.98 = -18.59

B: 7 2/5 -3/5 = 7 +(2/5 -3/5) = 7 -1/5 = 6 4/5

C: 3 1/6 +2 1/2 = (3+2) +(1/6 +3/6) = 5 4/6 = 5 2/3

D: 23.66 -15.84 = 7.82

__

Least to greatest, their order is ...

  A (-18.59), C (5 2/3), B (6 4/5), D (7.82)

Help... anyone????????
katovenus [111]
Since they both have 3x terms subtract the second from the first to get rid of the x terms...

  3x+2y=10
-3x+y=-13
__________
3y=-3

y=-1, which makes 3x+2y=10 become: 3x-2=10 so

x=4

So the solution is the point (4, -1)
