➷ (12/20) = 0.6
(8/20) = 0.4
The experimental probability of the coin landing heads up is 0.6. 
B) The theoretical would be considering it a fair coin. 
1/2 = 0.5
The theoretical probability would be 0.5

Answer:
3 feet
Step-by-step explanation:
12 inches = 1 foot
36 inches = 36 / 12 = 3 feet
 
        
             
        
        
        

<u>We </u><u>have </u><u>given </u><u>in </u><u>the </u><u>question </u><u>that</u><u>, </u>
- <u>The </u><u>sum </u><u>of </u><u>2</u><u> </u><u>numbers </u><u>is </u><u>equal </u><u>to </u><u>1</u><u>1</u><u> </u>
- <u>The </u><u>difference </u><u>between </u><u>two </u><u>numbers </u><u>is </u><u>1</u><u>9</u><u> </u><u>.</u>

- <u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>value </u><u>of </u><u>x </u><u>and </u><u>y</u><u>. </u>

Let the two numbers be x and y 
<u>According </u><u>to </u><u>the </u><u>question</u><u>, </u>


<u>Solving </u><u>eq(</u><u> </u><u>1</u><u> </u><u>)</u><u> </u><u>we </u><u>get </u><u>:</u><u>-</u><u> </u>


<u>Subsituting </u><u>eq(</u><u>3</u><u> </u><u>)</u><u> </u><u>in </u><u>eq</u><u>(</u><u>2</u><u>)</u><u> </u><u>:</u><u>-</u>









<u>Now</u><u>, </u><u> </u><u>Subsitute </u><u>the </u><u>value </u><u>of </u><u>y </u><u>in </u><u>eq(</u><u> </u><u>3</u><u> </u><u>)</u><u> </u><u>:</u><u>-</u>




Hence,  The value of x and y are 15 and (-4)  .
 
        
             
        
        
        
A is greater . That's the one
        
                    
             
        
        
        
The solution to the problem is as follows:
<span>√28 = √(4 * 7) = √4 * √7 = 2√7. 
</span>
<span>√64 = 8
</span>
Therefore, √28 + √64 = <span>2√7. + 8
