if you add 55% and 45% the total is 100% so 45/100 are girls. 35% of the girls scored and A so 35/45 is the probability that it is a girl chosen or 7/9. the probability is 7 out of 9.
Answer:
j=38
Step-by-step explanation:
j/-2 +7=-12, subtract 7 from both sides of the equation and you get j/-2 = -19, then you multiply j/-2 by -2/1 and multiply -19 by -2/1 to get j= 38
1 + 1x
OR
1 + x
They mean the same thing! Hope this helps!
Answer:
90
Step-by-step explanation:
it is 90 because in the first slot there can be any 10 numbers and in the second slot the set can contain any of the remaining 9 numbers and then we can multiply these two numbers together to find the total amount of sets.
hope this helps :)
Consider the given equations:
The first equation is as:

So, 
= 
Multiplying the given fractions, we get as
= 
Now, consider the second equation as:

Multiplying by '3' to both the sides of the equation, we get


So, the number which best completes both the equations is
.
