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:

10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

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:

10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36 is the number of different combinations of x objects from a set of n elements, given by the following formula.

10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

In this question:

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

92 fibers means that 10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

Sample of 10 means that 10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

No polymeter B which means that 10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

17 fibers of polymeter B which means that 10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

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

This is P(X = 0).

10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

10. A random sample of 10 fibers is taken from, №17887389, 08.07.2021 13:36

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
