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
Answer: 89
89 times 89 is 7921. Since 7921 is a 4 digit perfect square, it has 89 as its root. Square root of 7921=89
Answer:
2√6
Step-by-step explanation:
1. First, let's solve for the base of the triangle with the help of the Pythagorean Theorem (a^2 + b^2 = c^2).
2. Now, let's find the factors of 24 and see which one is a perfect square:
- 1, 2, 3, 4, 6, 8, 12, 24
- As you can see, the factor that's a perfect square is 4, so in order for it to multiply to 24, the other one has to be 6.
Therefore, the answer is 2√6.
