5x + 15y = 1200. x. | y
___________
105 | 45
30. | 100
60. | 60



5(x) + 15y = 1200. 5(x) + 15y = 1200. 5(x) + 15y = 1200.
5(x) + 15(45) = 1200. 5(30) + 15y = 1200. 5(x) + 15(60) = 1200
5x + 675= 1200. 150 + 15y = 1200. 5x + 900 = 1200
5x = 1200 - 675 15y = 1200 - 150. 5x = 1200-900
5x = 525 15y = 1050. 5x = 300
x= 525÷5. y= 1050÷15. x = 300÷5
x= 105. y = 100 x = 60

Stella [2.4K]

Answer:

8 different combinations are possible.

Step-by-step explanation:

Here, we have 2 different combinations for each time.

And the player comes out to bat 3 times.

So, total number of combinations are:

2^{3} i.e. a total of 8 number of times.

Let a hit is termed as 'H' and an out is termed as 'O'.

Total combinations are:

{HHH, HHO, HOH, HOO, OHH, OHO, OOH, OOO}

Kindly have a look at the tree diagram attached in the answer area.

In starting, there are 2 combinations possible, i.e. 'O' and 'H'.

After 'O' , 2 possible i.e. 'O' and 'H'.

After 'H' , 2 possible i.e. 'O' and 'H'.

and so on....
