Answer:

The distance from one base to the next is 90 ft. You can make a right triangle with two sides being 90 ft and the long side being the distance between home and second. Then you use the pythagorean theorem to find that distance.

90^2 + 90^2 = d^2

d = sqrt (16200) = 127.28 ft

At Brian’s Bookstore, 0.3 of the shelves hold mysteries, 25% of the shelves hold travel book and 7/20 of the shelves hold childr
elena-s [515]

Children books covers the most shelf space in the store

<em><u>Solution:</u></em>

From given,

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 25 %

Shelves hold children’s books = \frac{7}{20}

To find: Type of book that covers the most shelf space in the store

You cannot compare values which are in different forms, so you need to convert.

Let us convert the given values into decimal form

Shelves hold travel book = 25 %

Percentage can be converted to decimal by dividing by 100

\rightarrow 25\% = \frac{25}{100} = 0.25

Shelves hold children’s books = \frac{7}{20}

\rightarrow \frac{7}{20} = 0.35

<em><u>Which type of book covers the most shelf space in the store?</u></em>

Now we have converted them into decimal form

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 0.25

Shelves hold children’s books = 0.35

0.35>0.3>0.25

We can clearly see that, 0.35 is the highest decimal

Therefore, children books covers the most shelf space in the store

10. A random sample of 10 fibers is taken from a collection of 92 fibers that consists of 43 fibers of polymer A, 17 fibers of p
vazorg [7]

Answer:

0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B

Step-by-step explanation:

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

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)!}

In this question:

Fibers are chosen without replacement, which means that we use the hypergeometric distribution.

92 fibers means that N = 92

Sample of 10 means that n = 10

No polymeter B which means that x = 0

17 fibers of polymeter B which means that k = 17

a. What is the probability that the sample does not contain any fibers of polymer B

This is P(X = 0).

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}

P(X = 0) = h(0,92,10,17) = \frac{C_{17,0}*C_{75,10}}{C_{92,10}} = 0.1150

0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B

In a lot (collection) of 100 light bulbs, there are 5 defective bulbs. an inspector inspects 10 bulbs selected at random. find t
Vedmedyk [2.9K]
Probability of finding no defective bulb
=95/100*94/99....86/91
=95!/(85!) / (100!/90!)
= 110983/190120
=>
Probability of finding at least one defective bulb
=1-110983/190120
= 79137/190120
= 0.41625 (to 5 decimal places)
