Answer:

-35 degrees F

When mixed in equal parts with water (50/50), antifreeze lowers the freezing point to -35 degrees F and raises the boiling temperature to 223 degrees F. Antifreeze also includes corrosion inhibitors to protect the engine and cooling system against rust and corrosion.

Irina18 [472]

The probability that the error occurred when Engineer 2 made the mistake is 0.462 on the other hand the probability that the error occurred when the engineer 1 made the mistake is 0.538

Explanation:

Let $E_{1}$ denote the event that the 1st engineer does the work.so we write

$P(E)_{1}$ =0.7

Let $E_{2}$ denote the event that the 2nd engineer does the work .So we write

$P(E)_{2}$ =0.3

Let O denote the event during which the error occurred .so we write

$P(O/E_{1} )$ =0.02(GIVEN)

$P(O/E_{2} )$ =0.04(GIVEN)

The probability that the error occurred when the first engineer performed the work is $P(E_{1} /O)$

The probability that the error occurred when the first engineer performed the work is $P(E_{2} /O)$

Now we need to find when did the error in the work occur so we will compare the probability of the work done by engineer 1 and engineer 2

lets find the Probability of the Engineer 1

Using Bayes theorem,we get

$P(E_{1} /O)$ =0.02*0.7/0.02*0.7+0.04*0.3 = 0.014/0.026=0.538

lets find the Probability of the Engineer 2

$P(E_{2} /O)$ =0.04*0.3/0.02*0.7+0.04*0.3=0.012/0.026=0.462

Since ,0.462<0.538 so it is more prominent that the Engineer 1 did the work when the error occurred

Answer:

In these present generation, every day a new technology is coming. People are adopting these technologies very fast. If we think ," we have learned C language , now why to worry about java " . Then that is called you are bounding yourself to a technology. You are not ready for the growth.

With the invent of new technologies, if we have basic idea of how it works, we can simply implement it. At the end of day , it doesn't really matter how many lines of code you have written , it is just about efficiency. How Efficiently you are writing your code.

So, When Efficiency is the only thing that matters to the organizations , they are ready to take up new technologies and they will try to work-out with them. This is the trend in IT .Every month a new technology comes, respective people will be trained on that and they will implement/migrate the existing projects into new efficient model.

If we really learn and implement things using advance technologies , people will get an exposure to new technologies as well as the organization will get good impact on them , for spending resources on learning new technologies in the market. Apart from that , everyone will be happy for adopting new stack of technologies for them.

If we observe the existing technologies:

Programming languages are :

C, JAVA, PYTHON,R , SCALA

web development technologies:

HTML,CSS , JAVASCRIPT, ANGULAR,REACT , BOOTSTRAP , NODE.JS, MongoDB....etc

databases skills:

SQL, oracle,mySQL, postgres and so many cloud databases also available.

So, there are plenty of opportunities that are available . There are life time courses available to learn new technologies.

LEARN..RELEARN....UNLEARN

this is the motto of many organizations. They simply learn one technology and they'll forget it . If something new comes, they'll learn and implements it.This is the current trend in software industry.
