Answer:
There are 30 students in the class
Step-by-step explanation:
we can write a ratio as:
8:10 as 24:x
Writing this as an equation gives:
8
10
=
24
x
We can now solve for
x
while keeping the equation balanced:

Step-by-step explanation:
From a, the original number is 100x the new number.
So,if the new number is 1unit --> the original is 100x 1unit --> 100units
Add the two numbers together --> 1unit + 100units --> 101 units
We also know that the difference between the two numbers is 136.62
So 100units - 1unit --> 136.62
99units -> 136.62
1unit --> 1.38
101units --> 139.38

Answer:
0.14
Step-by-step explanation:
When the game starts, either thee will be a hit or a miss.
The probability of hit = 0.3
Probability of miss = 0.7
Further, after a hit, the probability of hit = 0.3
And the probability of miss= 0.7
Continuing in this way, if we get 2 continuous miss, the game will terminate.
Hence,
the probability of game to terminate = Probability of first miss + Probability of second miss
= 0.7 +0.7
= 0.14
