Answer:

Option d. 3/50 is the correct option.

Step-by-step explanation:

Total number of balls given in a box is 10. Out of which different balls are

Green = 3, Red balls = 5, Blue = 2.

One ball was randomly drawn so probability of getting a green ball will be = 3/10

Now the ball was replaced so total number of balls remains the same

Then the probability of getting a blue will be = 2/10

Therefore the probability of both the events simultaneously = (3/10)×(2/10)=6/100 = 3/50

Option d. 3/50 is the answer.

Step-by-step explanation:

The first arrow on the number line starts from 0, moves downwards 9 units from 0.

We would write this as -9.

Also, the next arrow starts moves from -9, 2 units downwards.

We would write this as -2

The addition equation would be:

Y=? What is Y? Please help me!
kumpel [21]
Answer:   y = 6 mi.  .
______________________________________________
Explanation:
______________________________________________
Area of a triangle = (½) * (base) * (height) ;

or,  A = (½) * b * h ;  or,  A = b*h / 2 ;
_____________________________________
Given:  A = 24.3 mi ² ;
           b = 8.1 mi 
___________________
Find the height, "h" ;  (in units of "miles", or , "mi" ).
__________________________
   Plug in the known values into the formula:

24.3 mi ² = (½) * (8.1 mi) *(h) ;
_____________________________
Solve for "h" (height) ;
_____________________________
(½) * (8.1 mi) = 4.05 mi  ;
______________________________
Rewrite: 
____________________________
24.3 mi² = (4.05 mi) *(h) ;  Solve for "h" ;
_________________________________________
 Divide each side of the equation by "(4.05 mi)" ; to isolate "h" on one side of the equation ; and to solve for "h" ; 
__________________________________________
   24.3 mi²  / 4.05 mi  = (4.05 mi) *(h)  / 4.05 mi ;
                                 
              →  6 mi  = h ;  ↔  h = 6 mi. 

              →      h = y = 6 mi.
