Steps to solve:
(4.7 x 10^4)(6.4 x 10^15)
~Combine like terms
(4.7 x 6.4)(10^4 x 10^15)
~Simplify
30.08 x 10^4+15
30.08 x 10^19
~Divide by 10 to get a number less then 10
30.08/10 x 10^19
3.008 x 10^20
Therefore, the answer is A) 3.008 x 10^20
Best of Luck!
Answer:
0.2752512
Step-by-step explanation:
The formula you are looking for is the binomial probability:
n!
P (X) = ------------ * (P)^X * (q)^n - X
(n- X)! X!
For your particular problem:
n=7
X=2
q = 1-p = .8
7!/(5!*2!)*(.2)^2*(.8)^5 = 0.2752512
Hope this helps, have a nice day/night! :D
Answer:5 or 5 degrees
the box means 90 degree so if you divide 45 with 90 you get 2
2 divided by 10 = 5
CD = 16.5
To find the distance between two points, use this formula:
point C can be info set 1: (10, -1) x₁ = 10 y₁ = -1
point D can be info set 2: (-6, 3) x₂ = -6 y₂ = 3
Substitute the information into the formula
Simplify inside each bracket
Square the numbers
Add inside the root
Enter into calculator
Rounded to the nearest tenth, the first decimal
The distance CD is 16.5.
Given
Required
Approximate (to the nearest 100th)
This means that, we approximate at the second digit after the decimal.
So:
i.e,
Number = 39.79 [Begin approximation] 949748
The first digit after [Begin approximation] is then approximated using the following rule:
Since 9 falls in category, the number becomes:
