Raul is practicing for baseball tryouts. he wants to find out how far he can hit a baseball. he hits the ball 10 times and measures the distance the ball travels each time. part a which measure should raul use to learn the average distance he hit the ball?
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257
The answer is 20
Step-by-step explanation:
what is double of 10
20
10 times 2 equals 20
Arcsin (2/5) = arctan(2/√21)
now as tan (arctan (x) ) = x
hence tan (arctan (2/√21)) = 2/√21 = 0.436
