You just add up all of the sides to find the x
Step-by-step explanation:
I have written the answer for you...You must know that diameter is twice the radius.
Cos θ=1/3
cos θ=sen (90-θ)
therfore:
sen (90-θ)=1/3
To chek
θ=arc cos 1/3=70.53º
sin (90-θ)=sin (90º-70.53º)=sin 19.47≈0.3333≈1/3
Answer:
0.1997 or 19.97%
Step-by-step explanation:
Have taken course online (H) = 23%
Have NOT taken course online (N) = 77%
Have taken course online and don't believe they provide same value (H&D) = 61%
Have NOT taken course online and don't believe they provide same value (N&D) = 73%
The probability that a student has taken a course online given that she does not believe that online courses provide the same educational value as one taken in person is;

There is a 0.1997 or 19.97% chance that she has taken an online course before.
Answer:
P = 1/216
the probability that you would roll 3 sixes is 1/216
Step-by-step explanation:
For a given dice, there are six possibilities.
We have;
1,2,3,4,5,6
The probability of rolling a six(6) is;
P(6) = 1/6
Then, the probability of rolling 3 sixes is a multiple of the P(6), given as;
P = P(6) × P(6) × P(6)
P = 1/6 × 1/6 × 1/6
P = 1/216
the probability that you would roll 3 sixes is 1/216
