9x + 27 = -72
- 27 = - 27
9x = - 99
9x/9 = -99/9
x = -11
If

and

are mutually independent, then

and

.
If

and

are independent, then

. Ditto for

and

.
The inclusion/exclusion principle says that

Since

and

are mutually exclusive, their intersection is the empty set. It then follows that

also is the empty set, so the last probability is also 0.
Plug in what we know:

Answer: n < 6
Step-by-step explanation:
multiply both sides.
4 + n/3 < 6
move the constant to the right.
12 + n < 18
calculate.
n < 18 - 12
solution:
n < 6
So 4:30 and then the second one is 15:75
Hi there!
To Round of the number given, first you have to find the ten thousands place on the given number. Started from ones, tens, hundreds, and moving on, the number in the ten thousands place would be 7 in your case.
Now, looking to the number on the right of 7 which is 8, it is bigger than 5, and therefore, we round up 7 and let 8 go to zero.
Applying this, your answer would be 4,280,003
Hope this helped!
