The caty
Answer:
Greater fraction is

Step-by-step explanation:
we are given two fractions
and 
First fraction:

Second fraction:

We can simplify it


To compare them , firstly we should make common denominator
denominators are 7 and 5
so, common denominator is

now, we can make each denominator as 35





so, we can see that both fractions have common denominator =35
and greater numerator is 30
so,
Greater fraction is

Answer:
90.91% probability that a car needs an oil change given that it has a certain factory defect
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this problem, we have that:
Event A: having a factory defect.
Event B: needing an oil change.
The probability that a car has a certain factory defect is 825.
So 
The probability that a car has a certain factory defect and needs an oil change is 750.
So 
What is the probability that a car needs an oil change given that it has a certain factory defect

90.91% probability that a car needs an oil change given that it has a certain factory defect
Answer:
15
Step-by-step explanation:
If you replace each answer choice with the varibale, (x) then 15 would be the only choice that fits properly.
Equation:
20-x = 35-(2x)
when replacing 15 with x this is your new equation...
20-15 = 35-(2x15)
5 = 35-30
5=5
