Reduce the fraction to lowest terms. y+5/2y+10A:1/4B:1/2C:2/5
1 answer:
The given fraction is:
We cannot take anything common from the numerator but from the denominator we can take out 2 as common because 2 is a factor of both the terms i.e. 2y and 10.
2y + 10 can be written as 2y +2(5) which can further be written as 2(y+5)
So, our fraction now becomes:
y+5 occurs in both the numerator and denominator and thus be cancelled out leaving behind:
Therefore, the given fraction in lowest term is equal to 1/2. So option B is the correct answer

Answer:
There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.
Step-by-step explanation:
is the number of different combinatios of x objects from a set of n elements, given by the following formula.
In this problem, we have that:
Total number of combinations:
Desired combinations:
It is 1 one 5(contamined) and 2 of 17(non contamined). So:
What is the probability that exactly 1 of the tested bottles is contaminated?
