A her of 40 horses has 9 white and some black horses. What is the ratio of white to black horses?​
solmaris [256]

Answer:

The number of white horse to white horse is 9 : 31

Step-by-step explanation:

Given as :

The Total number of horses = 40

The number of white horses = 9

Let the number of black horses = x

So, x + 9 = 40

Or x = 40 - 9 = 31

∴ The number of black horses = 31

Now,  The ratio of while to black horses = number of white horse : number of black horse

Or, number of white horse : number of black horse = 9 : 31

Hence The number of white horse to white horse is 9 : 31   Answer

BaLLatris [955]

Using the binomial distribution, it is found that the true statement related to the number of cans of cat food the company expects to be dented is given by:

B. The factory can expect to have an average of 50 cans dented in a day.

<h3>What is the binomial probability distribution?</h3>

It is the probability of exactly<u> x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

In this problem, we have that there are 1000 cans, each with a probability of 1/20 of being dented, hence:

n = 1000, p = 1/20 = 0.05.

The expected value is then given by:

E(X) = np = 1000 x 0.05 = 50.

Researching the problem on the internet, the correct option is given by:

B. The factory can expect to have an average of 50 cans dented in a day.
