Answer:
A jewellery shop is having a sale.
A bracelet is reduced to £240.
a) What is the original price?

Answer:
import numpy as np
a = int(input ("Enter a"))
b = int(input ("Enter b"))
c = int(input ("Enter c"))
d = int(input ("Enter d"))
c1 = int(input ("Enter c1"))
c2 = int(input ("Enter c2"))
array1 =[[a, b],[c, d]]
A = np.array (array1)
B = np.array ([c1, c2])
X = np.linalg.inv (A).dot (B)
print (X)
Explanation:
let ax + by =c1
cx + dy =c2
We have used the above NumPy library that has the methods for matrix calculation, and here we have used matrix multiplication, and the inverse of a matrix to find the value of x and y.
We know AX=B
X = inv A. B
And this we have used above. We can calculate inv A and do matrix multiplication using NumPy. And thus we get the above solution.
Answer:
a. IEEE
Explanation:
The organization with the acronym 'IEEE' is commonly known as the Institute of Electrical and Electronics Engineer. The organization is responsible for the standardization and implementation of various important modes such as the XTS-AES. This is widely used for data encryption and it is a major part of the AES algorithm.

Answer:
The correct answer is C. One reason why a business may want to move entirely online is to focus on a global market.
Explanation:
The fact that a business wishes to move entirely towards the online sales modality implies that there is a desire to expand the possibilities of selling its products beyond the physical place where it has its store.
It is a reality that starting an online business implies that the offered product can be purchased anywhere in the world, thanks to advances in technology and transportation that allow the product to be purchased and delivered in a matter of days, thanks to the advances produced by globalization.
Therefore, the fact that the store goes from physically to online selling makes its potential customers go from being the ones who know the store and live close to it to everyone in the world with access to internet.
