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:
(25/100, 25/100, 80/100, 62.5/100, and 1/100) |-1/100--25/100--25/100--62.5/100--80/100-| is the order it should go or so on so forth
Answer:
a) 1/3
b) 12/44
Step-by-step explanation:
To find the answer to a you must simplify the fraction 16/48 which would give you 1/3.
To find the answer to b you must first subtract 16 from 48 and then add 12. You should get 44 so your ratio of passengers who got on the bus at the stop compared to the new total then on the bus would be 12/44.
