Answer:
1) Mean 2) Standard deviation 3) symmetric
Step-by-step explanation:
The addition of a negative is basically the same as subtraction.
Since your adding -35 to 90, your just taking away 35 from 90.
You would set up the problem like this:
90 + – 35
Or you could write it out like this:
90 – 35
Either way, 90 + – 35 = 55
Remember, -(-x)=x because the negatives cancel out
so
when p=-6 and q=7
p+(-q)-3
-6+(-7)-3
-6-7-3
-13-3
-16
