A data scientist is writing a Machine Learning (ML) algorithm using a large data set.

Olenka [21]

The product of the data scientist, who writes a Machine Learning (ML) algorithm using a large data set, is called a data-driven model.

A data-driven model generates insights and increases the efficiency of decision-making.

This implies that decisions are made based on the insights that the model by the Machine Learning algorithm produces.

Thus, Machine Learning algorithm or code helps entities to make insightful business decisions to increase efficiency and effectiveness.

Develop an sec (single error correction) code for a 16-bit data word. generate the code for the data word 0101000000111001. show

Kipish [7]

Answer:

code = 010100000001101000101

Explanation:

Steps:

The inequality yields $2^{k} - 1 > = M+K$ , where M = 16. Therefore,

The second step will be to arrange the data bits and check the bits. This will be as follows:

Bit position number Check bits Data Bits

21 10101

20 10100

The bits are checked up to bit position 1

Thus, the code is 010100000001101000101

Acceleration is the rate at which an object changes its velocity. It is typically represented by symbol a and measured in m/s2 (

Natalija [7]

Answer:

Pseudocode:

INPUT velocity

INPUT time

SET velocity = 0.44704 * velocity

SET acceleration = velocity / time

SET acceleration = round(acceleration, 1)

PRINT acceleration

Code:

velocity = float(input("Enter a velocity in miles per hour: "))

time = float(input("Enter a time in seconds: "))

velocity = 0.44704 * velocity

acceleration = velocity / time

acceleration = round(acceleration, 1)

print("The acceleration is {:.2f}".format(acceleration))

Explanation:

*The code is in Python.

Ask the user to enter the velocity and time

Convert the miles per hour to meters per second

Calculate the acceleration using the formula

Round the acceleration to one decimal using round() method

Print the acceleration with two decimal digits
