Answer:
ok so this is kinda hard to explain but. what I got out of it was since you are doing you know adding pos with neg so listen when you add something like a pos and a neg you put the pos on top right then you take and put the neg on bottom then you cross out how ever many negatives are there until there is no more negatives left right but that means your also gonna have to cross out how ever many neg there are with positives and if there are more negatives than positives your answer will be negative as well then you just count how many positives arent crossed out and then that would be your answer ect.

Answer is 2
because from -2 plus 2 = 0
Answer:
0.8188 or 82%
0.0000643
Step-by-step explanation:
Given that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .0278 in.
If x is the dimension then X is N(0.0276, 0.0001)
Or
is Normal (0,1)
a) Fraction of shelf depths are in specifications
=
b) For 98% to be within the specifications,

Margin of error = 
For 98% critical value Z two tailed is 2.33
Hence std error = 
So sigma should be = 0.0000643
Answer:
first option
Step-by-step explanation:
3x - 7y and - 7y + 3x are equivalent expressions
3x is positive and - 7y is negative
As long as the signs on their coefficients do not change then they can be reversed, that is
3x - 7y = - 7y + 3x
Zach is 14 bc...
-4 years older(+4) than twice (x2) Mayas age.
-Maya is 5
- the correct order is 5x2+4
-5x2=10, 10+4=14
