Answer: 0.263169
Step-by-step explanation:
Since for every child there is two outcomes (either a boy or a girl), so it is a binomial distribution.
Let x = Number of boys
Given: probability that a child is a boy: p= 0.513
Binomial distribution formula :
Now, the probability that both children are boys=
The chance both children are boys = 0.263169
2 is 1/3 of 6 so it would be
200/1
Answer:
A. 15
Step-by-step explanation:
Ooh, look! This triangle is a Pythagorean triple! Without even needing to use a formula, I can tell that you are correct and the answer is A. 15.
It's based off of a 3-4-5 right triangle, because 9-12-15 simplifies to that if you divide every term by 3. It's basically just a bigger version of a 3-4-5 triangle! Isn't math cool:)
Answer:
13. 4 sqrt(3)
14. sqrt(7)/2
Step-by-step explanation:
13. sqrt(2) * sqrt(3) * sqrt(8)
We know sqrt(a) * sqrt(b) = sqrt(ab)
sqrt(48)
Look for perfect squares
sqrt(16*3)
sqrt(16) sqrt(3)
4 sqrt(3)
14. sqrt(14)/ 2 sqrt(2)
We know sqrt(a) / sqrt(b) = sqrt(a/b)
sqrt(14/2) / 2
sqrt(7)/2
