Answer:
P(cell has at least one of the positive nickel-charged options) = 0.83.
P(a cell is not composed of a positive nickel charge greater than +3) = 0.85.
Step-by-step explanation:
It is given that the Nickel Charge Proportions found  in the battery are:
0 ==> 0.17
.
+2 ==> 0.35
.
+3 ==> 0.33
.
+4 ==> 0.15.
The numbers associated to the charge are actually the probabilities of the charges because nickel is an element that has multiple oxidation states that is usually found in the above mentioned states.
a) P(cell has at least one of the positive nickel-charged options) = P(a cell has +2 nickel-charged options) + P(a cell has +3 nickel-charged options) + P(a cell has +4 nickel-charged options) = 0.35 + 0.33 + 0.15 = 0.83.
Or:
P(a cell has at least one of the positive nickel-charged options) = 1 - P(a cell has 0 nickel-charged options) = 1 - 0.17 = 0.83.
b) P(a cell is not composed of a positive nickel charge greater than +3) = 1 - P(a cell is composed of a positive nickel charge greater than +3) 
 = 1 -  P(a cell has +4 nickel-charged options)  '.' because +4 is only positive nickel charge greater than +3       
= 1 - 0.15
=  0.85
To summarize:
P(cell has at least one of the positive nickel-charged options) = 0.83!!!
P(a cell is not composed of a positive nickel charge greater than +3) = 0.85!!!
 
        
             
        
        
        
Answer:
A
Step-by-step explanation:
rational numbers are numbers that can be expressed as fractions.
e.g. 1 , 1/2, 2/7
 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
In the original expression =  37.4 - 54.9 = -17.5 
So, we have to solve all the equations but 1 of them has to equal to -17.5
A) -54.9 + (-37.4) = -92.3
    Remove parentheses
    = -54.9 - 37.4
Subtract the numbers
     -92.3
B) 54.9 - 37.4 = 17.5
 Since 54.9 is greater than 37.4 just subtract normally
  4   14
   5  4.   9                < ------- Line up the decimal points like this
-  3  7.   4                <---------  Subtract the decimals
-----------------
    1   7   .    5       <---------- This is the final answer to B.                     
  
C)  37.4 - (- 54.9) = 92.3
    Change the sign to addition
         =37.4 + 54.9
   Add the numbers normally
   54.9
+ 37. 4
--------------
   92.3
D)  37.4 + (-54.9) = -17.5
    Change the sign to subtraction
       =    37.4 - 54.9
Subtract them normally (but as you can see you are subtracting a smaller number from a larger number so heres a trick that you can use switch the equation by putting the larger number in first like this....)
54.9 - 37.4 = 17.5 (REMEMBER the answer is not 17.5 because the original equation of D is reversed  37.4 - 54.9 so in this case your answer should be
 - 17.5)
37.4 - 54.9 = -17.5
Your final answer is D because it matches 37.4 - 54.9.
Hope this helps!
 
        
                    
             
        
        
        
In a meter there are 100 cm.
In 100 cm there are 1000 mm. 
Therefore in 1 meter you have 1000 millimeters. 
Then to find out how many millimeters you have in 14 meters, you just multiply 14 by 1000 to give you 14000 mm.
Final answer= 14 m of gold wire is the equivalent to 14000 mm of wire.
