The diagram of the right-angled triangle is shown below
Using the Pythagoras theorem
6² = a²+a²
36 = 2a²
18 = a²
a = √18 = 3√2
change to improper fractions
8 1/2 = (2*8+1)/2 = 17/2
2 1/4 = (4*2+1)/4 = 9/4
17/2 divided by 9/4
copy dot flip
17/2 *4/9
17/9 *4/2
34/9
change back to a mixed number
3 remainder 7
3 7/9
Answer:
0.956
Step-by-step explanation:
X is the random variable representing the number of successes in the experiment in question;
X is represented by a binomial distribution with 5 trials and 0.18 probability of success, X~B (5, 0.18);
The probability of r successes, P(X=r), is found using the formula shown in second pic;
Working is shown in the other pic.
