A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that
snow_tiger [21]

Answer:

12800 + 100x \le 24000

A maximum of 112 number of 100 - kilograms can be loaded in the container.

Step-by-step explanation:

Given that:

Weight of each crate = 100 kg

The greatest weight that can be loaded in the container = 24000 kg

Weight already loaded in the container = 12800 kg

To find:

The inequality to determine the value x i.e. number of 100 - kilograms that can be loaded in the shipping container?

Solution:

Weight already loaded = 12800 kg

Let the number of 100 - kilograms that can be loaded in the container = x

Weight of x = 100x kg

This combined weight nor be greater than the capacity of the container.

OR we can say, it must be lesser than or equal to greatest weight that can be loaded into the container.

12800 + 100x \le 24000

100x \le 24000 - 12800\\\Rightarrow 100x \le 11200\\\Rightarrow x \le 112

i.e. a maximum of <em>112</em> number of 100 - kilograms can be loaded in the container.

In 2012, Red Rose tea randomly began placing 1 of 12 English porcelain miniature figurines in a l00-bag box of the tea, selectin
Mandarinka [93]

Answer:

n = 144 bags

Step-by-step explanation:

Given:-

- English porcelain miniature figurines in total = 12

- 1 figurine is to be placed in a 100-bag box

Find:-

On the average, how many boxes of tea must be pur-chased by a customer to obtain a complete collection consisting of the 12 nautical figurines?

Solution:-

- We will denote a random variable (X) as the number of figurines in (n) number of bags purchased.

- The probability (p) of finding a figurine in a single bag is ( success ):

                                 p = 1 / 12

- The random variable (X) can follow a binomial distribution with parameters n = number of bags purchased, and p = probability of selecting a bag with a figurine.

                                X ~ B ( n , 1/12 )

- The average number of bag "n" that need to be purchased to find all 12 figurines available:

                               E ( X ) = 12

                               n*p = 12

                               n = 12 / p

                               n = 12 / ( 1 / 12) = 12^2

                               n = 144 bags

- A total of average n = 144 bags need to be purchased to find all the 12 figurines.
