Answer:

You multiply 5 by the exponents and 4^0 is just 1, so 4^45•1=4^45. Hope this helped!

Nat2105 [25]
For this problem, it could be mistaken to be decay rate which is exponential. But this is actually logical to simple interest in economics.The difference would be, the principal amount and future amount are interchanged because it is decreasing. Using the formula for simple interest,

Year 1950 = Year 2010 (1 + rate*time)
The time would be 2010-1950 = 60 years

114.6 = x(1 + 0.066*60)
x = 23.1 million tons

Simplify the F = ABC + A’B + ABC
madam [21]

Well, from what I can tell, we just have to combine like terms, meaning that all of the terms that have the same variables can be combined:

F = (ABC + ABC) + A'B

F = 2ABC + A'B

If that's not what you meant, or if you have questions, feel free to let me know! :)

If one of the 50 states is chosen at random, then a standard die is rolled, Find the probability of getting a state that starts
Black_prince [1.1K]

Answer:

The final answer is 2/15 or 0.133

Step-by-step explanation:

The US States that start with an "N" are:

  1. Nebraska
  2. Nevada
  3. New Hampshire
  4. New Jersey
  5. New Mexico
  6. New York
  7. North Carolina
  8. North Dakota

The probability of selecting a state that starts with an N is 8/50

The probability of rolling at least a two is 5/6.

If we multiply the two probabilities together, we get 2/15.
