In a class there are 30 boys and 10 girls. what percent are girls?​
musickatia [10]

Answer:

I believe the answer would be 10%

Step-by-step explanation:

If you take 10% of 40 you get 4% however 40 is your total (100%) so therefore you would take the 4% multiply it by 2 and then you end up with 8% then you take 4% and divide it by 2 then add it on to your 8% then you end up with 10%

Hope this helps!

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p
Verizon [17]

Answer:

P(X = 17) = 0.3002

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

n = 18, p = 0.9

We want P(X = 17). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 17) = C_{18,17}.(0.9)^{17}.(0.1)^{1} = 0.3002

P(X = 17) = 0.3002

Do you inverse to slove
lys-0071 [83]

Answer: Yes, In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.
