Answer:
1/3
Step-by-step explanation:
The number of people over 40 is 20 + 30 + 35 = 85.
So the probability is 85/255, which reduces to 1/3.
The absolute value of -5 is 5 (absolute value being how many units to 0)
So we really have 5 - 45 ÷ 3 =
Order of operation says to do the division first (there are no parentheses or exponents). So now we have 5 - 15= and the answer to that is -10.
Answer:
False
True
False
False
Step-by-step explanation:
1. We have to get the sum as follows :

= 
= 
= 
= 
So, this is false.
2. We have to get the sum as follows :

= 
= 
= 
= 
So, this is true.
3. We have to get the difference as follows :

= 
= 
= 
= 
So, this is false.
4. We have to get the difference as follows :

= 
= 
= 
= 
So, this is also false. (Answer)
