Answer: 99.73%
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Let X be the random variable that represents the data values.
Formula for Z-score : 
For x=94, we have
For x=106, we have
The probability that the samples are between 94 and 106:-
Hence, the percent of the samples are expected to be between 94 and 106 = 99.73%
Answer: I prefer long division because that is the method I understand
Step-by-step explanation:
I prefer long division because that is the method I understand .for example
(x^2+3x+2) ➗ (x+2)
x+1
|````````````````````````
x+2 x^2+3x+2
-(x^2+2x)
````````````````````````````
x+2
- (x+2)
````````````````````````
0
`````````````````````````
therefore (x^2+3x+2) ➗ (x+2)=x+1
Answer:
x = 7/2 ± 3/2*(i√3)
Step-by-step explanation:
The equation is
(x - 5)^2 + 3(x - 5) + 9 =0
Let A = (x-5)
The equation becomes now
(A)^2 + 3(A) + 9 =0
We then apply the quadratic formula
A = [-(3) ± √((3)^2-4(1)(9)) ]/ (2(1))
A = -3/2 ± 3/2*(i√3)
Now, we revert the substitution
(x-5) = -3/2 ± 3/2*(i√3)
x = 7/2 ± 3/2*(i√3)
Answer:
choice b
Step-by-step explanation:
when x is + or - 6 or x = 0
the domain will be 0
so choose choice b
