solution is first os all find median 
median is( 45+61)/2=53
find median of no in left of 53
it is 37
find median of no in right of 53
it is 64
now interquartile range=64-53=27
 
        
             
        
        
        
Answer:
-24
Step-by-step explanation:
Easy way: 42 - 18 = 24, then translate it to negative 24 because your numbers are negative.
A little bit harder way: -42 + (-18) or -42 + 18 = -24
 
        
             
        
        
        
P of selecting point on the shaded region   = shaded area/whole area 
<span>P( selecting point on the shaded ) = ( the four shaded circles ) / the whole square </span>
<span>P of  selecting point on the shaded  = ( 4 * ( π * r^2 ) )/ x^2 </span>
<span>P of selecting point on the shaded = ( 4 * ( π * (x/4)^2 ) )/ x^2 </span>
<span>P of  selecting point on the shaded  = ( 4 * ( π * x^2/16 ) )/ x^2 </span>
<span>P of  selecting point on the shaded = ( π * x^2/4 )/ x^2 </span>
<span>P of  selecting point on the shaded = x^2( π/4 )/ x^2 </span>
<span>P( selecting point on the shaded ) = π/4 ≈ 0.7854 ≈ 79%
 =80% 
D is right option hope this helps</span>
