Answer:
12000
Step-by-step explanation:
1 kilo = 1000 grams 
12 kilo = ? grams 
1 x 12 = 12
1000 x 12 = 12000
 
        
             
        
        
        
Answer:
The probability is: 0.8889.
Step-by-step explanation:
Conditional Probability
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.
 is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Approved
Event B: Qualified
Probability of a person being approved:
80% of 75%(qualified)
30% of 25%(not qualified). So

Probability of a person being approved and being qualified:
80% of 75%, so:

Find the probability that a person is qualified if he or she was approved by the manager.

The probability is: 0.8889.
 
        
             
        
        
        
Answer:
There are two rational roots for f(x)
Step-by-step explanation:
We are given a function

To find the number of rational roots for f(x).
Let us use remainder theorem that when
f(a) =0, (x-a) is a factor of f(x) or x=a is one solution.
Substitute 1 for x
f(1) = 1-2-5+6=0
Hence x=1 is one solution.
Let us try x=-1
f(-1) = 1-2-5+6 =0
So x =-1 is also a solution and x+1 is a factor
We can write f(x) by trial and error as

We find that  factor gives two irrational solutions as
 factor gives two irrational solutions as
±√3.
Hence number of rational roots are 2.
 
        
                    
             
        
        
        
Since X is any number of hours, finding the distance traveled would be represented as 65x. To find the remaining, you would need to subtract, so it'd look like this: 986-65x. The best thing to do with problems like these is to take it slowly, and highlight the important parts if possible!
