Answer:
The larger number is 69 and the smaller number is 35.
Step-by-step explanation:
Find the equations. Here x will be the larger number and y will be the smaller number.
x + y = 104
x = 2y -1
Substitute:
(2y -1) + y = 104
3y = 105
y = 35
x = 2(35) - 1
x = 70 - 1
x = 69
The larger number is 69 and the smaller number is 35.

a. 9:00 AM is the 60 minute mark:

b. 8:15 and 8:30 AM are the 15 and 30 minute marks, respectively. The probability of arriving at some point between them is

c. The probability of arriving on any given day before 8:40 AM (the 40 minute mark) is

The probability of doing so for at least 2 of 5 days is

i.e. you're virtually guaranteed to arrive within the first 40 minutes at least twice.
d. Integrate the PDF to obtain the CDF:

Then the desired probability is

A=3 and B=1. comment if you would like me to explain how I did it.
140.66
you divide $422 by 3 to get $140.66
Answer:
A. ![(-\infty, -4]\ or\ (2,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-4%5D%5C%20or%5C%20%282%2C%5Cinfty%29)
Step-by-step explanation:
Given:
The inequality is given as:

Now, consider the first inequality

Here, 'x' is less than or equal to -4. The values that are less than -4 are -5, -6, -7... so on. The inequality used is 'less than or equal to'. This means that -4 is included in the solution. So, we use a square bracket (closed interval) at the other end.
The inequality in notation form is thus, ![(-\infty,-4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-4%5D)
Now, consider the other inequality 
The values of 'x' are greater than 2. The values that are greater than 2 are 3, 4, 5... and so on. Also, 2 is not included in the solution. So, we use open interval on either side.
Therefore,
in interval notation form is 
There is a conjunction 'or' used in the inequality. Therefore, the answer is:
A. ![(-\infty, -4]\ or\ (2,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-4%5D%5C%20or%5C%20%282%2C%5Cinfty%29)
