The Copy Shop has made 20 copies of a document for you. Since the defective rate is 0.1, you think there may be some defective c

Pepsi [2]

Answer:

Binomial

There is a 34.87% probability that you will encounter neither of the defective copies among the 10 you examine.

Step-by-step explanation:

For each copy of the document, there are only two possible outcomes. Either it is defective, or it is not. This means that we can solve this problem using the binomial probability distribution.

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 combinatios 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

Of the 20 copies, 2 are defective, so $p = \frac{2}{20} = 0.1$ .

What is the probability that you will encounter neither of the defective copies among the 10 you examine?

This is P(X = 0) when $n = 10$ .

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

$P(X = 0) = C_{10,0}.(0.1)^{0}.(0.9)^{10} = 0.3487$

There is a 34.87% probability that you will encounter neither of the defective copies among the 10 you examine.

Write the ratio as a fraction in simplest form. 10.8 seconds : 36 feet (Show work)

vodka [1.7K]

Answer: Ratio as a fraction in simplest form is :

$\frac{27}{1}=27$

Step-by-step explanation:

Since we have given that

10.8 seconds : 36 feet

As we know that

$1\ second=\frac{1}{60}\ mile\\\\1\ second=90\ feet$

So, we use it :

10.8 seconds : 36 feet

$=10.8\times 90\ feet:36\ feet\\\\=972:36\\\\=27:1$

Hence, Ratio as a fraction in simplest form is :

$\frac{27}{1}=27$

A broken rectangular shaped window is being replaced. It measures 24 inches by 18 inches. How many square inches of glass are ne

olya-2409 [2.1K]

Sorry, I can't draw a picture, but I can help answer the question...

The way to determine the area of a square or rectangle is to multiply the base and the height, which in this case, is 24 and 18. So 24 times 18 is 432. Therefore, the amount of glass needed to repair the window is 432 inches squared.

Hope that helps!
