For the answer to the question above,
For<span> a) Mean time required for the entire process = (40+25) = 65 minutes
b) Variance time required for the entire process = (2^2+1^2) = 5 minutes
Standard deviation time required for the entire process = sqrt(5) = 2.236 minute.
I hope my answer helped you

Answer:
Step-by-step explanation:
The real part does not have i as a multiplier. It is 23.3.
The imaginary part* is the coefficient of i: 44.
_____
* There is some disagreement as to whether the imaginary part includes i or not. One source says the imaginary part is the part that has i as a factor (44i). Another source says the imaginary part is the real number that multiplies i (44). Above, we have used the latter definition. Please consult your curriculum materials for the definition you should use.
Answer:
There are four addition properties that help to add whole numbers :
For any whole number a, b, and c ;
1. <u>Closure property of addition </u>- 
For example:
2+3=5
4+3=7
We can conclude that if we add any two whole number , we get another whole number.
2. <u>Associative property of addition</u>- when any whole number or variable are added, then that can be grouped in different way without changing result
For example:
2+(3+4)=(2+3)+4
3.<u> </u><u>Commutative property of addition</u>- when any whole number or variable are added, then the order changed without changing the result.
For example: 2+3=3+2
4. <u>Identity property of addition</u>- when 0 is added to a whole number or variable , the result is the same variable or number.
For example: 3+0=0+3
0 is called an Identity for addition of whole numbers.
Answer: B. -2/3 the amount of water decreases every 3 minutes!
Step-by-step explanation:
B because it starts with 14 gallons with 0 minutes and the slope goes go down 2 and run 3 so therefore, the answer is B because from 14 gallons and 0 minutes it goes to 3 minutes 12 gallons and 6 minutes and 10 gallons so it decreases 2 gallons everything 3 minutes!
