Answer:
X = 262 days
Step-by-step explanation:
For Normal Distribution N( 0,1) we have z table and we can find z score for value of 15 % or 0,15. As 0,15 is not in the table we extrapolate then
0,1492 ⇒ 1,4
0,1515 ⇒ 1,3 0,15 ⇒ x 0,1515 - 0,15 = 0,0015
Δ = 0,0023 ⇒ 0,1
By rule of three
If 0,0023 ⇒ 0,1
0,0015 ⇒ x
x = 0,0652
Therefore the value between 1,3 and 1,4 is:
1,4 - 0,0652
z (score ) = 1,3348 and as we are looking for values below the mean ( that is at the left of the bell shape curve we need to change the value to a negative one z = - 1,3348
Now when N ( 278 , 12 ) is normalized to N ( 0 , 1)
z( score ) = ( X - μ ) / σ
- 1,3348 * 12 = X - 278
X = 278 - 16,0176
X = 278 - 16
X = 262 days
Answer:
i think it is -c+40
Step-by-step explanation:
i hope that this helps
The two equations represent parallel
When put into y=mx+b form, they both result in the equation y= -4/5x + 4/5
This causes them to overlap, meaning that they are parallel to one another.
Answer:
D)
Step-by-step explanation:
The given equation is
Before, solve this equation, we have to get rid off the radical sign.
So we move the second term on the other side.
Since we have to radical of 4, we need to raise the power to 4 on both sides
Thank you.
