Petra notices that there are a number of issues with a new fiber optic connection whose status appears to be going up and down c
DanielleElmas [232]

Fiber Internet is the wired choice of our present times. It has replaced traditional copper-based facilities.

<h3></h3>

How fiber optics are connected?

  • Fiber to the curb (FTTC) means your fiber connection goes to the nearest pole or utility box—not an actual concrete curb. After that, coaxial cables will send signals from the “curb” to your home. This means your connection is made up of part fiber-optic cables, part copper wires.
  • Twisted pair cabling simply refers to a wiring whereby two conductors that are gotten from a single circuit will be twisted together so that their electromagnetic compatibility can be enhanced.
  • This type of network cable is commonly used to connect office computers to the local network and it is used for Ethernet networks. A circuit is formed from the pair of wires which can be used in the transmission of data.
  • Fiber optic internet is a data connection carried by a cable filled with thin glass or plastic fibers. Data travels through them as beams of light pulsed in a pattern. Fiber optic internet speeds are about 20 times faster than regular cable at 1 Gbps.

Write a function call it isEvenPositiveInt which takes an integer x and return true if x is positive and also even. Note isinsta
Anna11 [10]

Answer:

The program to this question as follows:

Program:

def isEvenPositiveInt(x): #defining method isEvenPositiveInt

   if x>0: #checking number is positive or not

       if x%2==0: #check true condition

           return True #return value True

       else:

           return False #return value False

   return False #return value False

print(isEvenPositiveInt(24)) #calling method and print return value

print(isEvenPositiveInt(-24)) #calling method and print return value

print(isEvenPositiveInt(23)) #calling method and print return value

Output:

True

False

False

Explanation:

In the above Python program, a method "isEvenPositiveInt" is defined, that accepts a variable "x" as its parameter, inside the method a conditional statement is used, which can be described as follows:

  • In the if block the condition "x>0" is passed, that check value is positive, if this condition is true, it will go to another if block.
  • In another, if block is defined, that checks the inserted value is even or not, if the value is even it will return "true", otherwise it will go to the else part, that returns "false".

You trained a binary classifier model which gives very high accuracy on thetraining data, but much lower accuracy on validation
kompoz [17]

Answer:

a. This is an instance of overfitting.

Explanation:

In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.
