Two rules for creating a pattern are given below. Each rule begins with a number called the input ar creates a number called the output.

20 Input

10 output

Step-by-step explanation:

Here, we want to select the input and output that works

From the diagram, the correct answer is 20 and 10

Let us look at how the rule is followed;

divides input by 2

20/2 = 10 which is the output

Subtract 10 to get output

20-10 = 10

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
