Let W represent the number of attempted experiments to get one experiment that is not successful. The random variable W has a geometric distribution with mean 4 and standard deviation 3.5. Which of the following is the best interpretation of the standard deviation?
A single value randomly selected from the distribution of W will vary from 4 by 3.5 attempted experiments.
B A single value randomly selected from the distribution of W will vary from 3.5 by 4 attempted experiments.
C Values of W typically vary from 4 by about 3.5 attempted experiments, on average.
D Values of W typically vary from 3.5 by about 4 attempted experiments, on average.
E The standard deviation of a random sample of values selected from the distribution of W will be 3.5 attempted experiments.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
