Answer:
129
Step-by-step explanation:
PEMDAS (parenthesis, exponents, multiplication / division, addition /subtraction.) I will use these as abbreviations.
8^2 + 9 (12/3*2) - 7
P: Start with P, and inside P go left to right with M/D
D: 8^2 + 9 (4*2) - 7
M: 8^2 + 9 (8) - 7
E: The next step is E, so I will do 8^2
64 + 9 (8) - 7
M/D: I will then multiply from left to right
64 + 72 - 7
A/S: Finall I will add and subtract from left to right.
A: 136 - 7
S: 129

1/6 Answer
The answer to this question would be: <span>The new survey’s margin of error will be between 50% and 100% the size of the original survey’s margin of error.
A bigger sample will result in a narrower margin of error which is a good thing because your data will become more accurate. But twice size will not improve the margin into the half. It definitely became lower than 100% though

Answer:
f(x)= x^2 - 2, the one in red.
Step-by-step explanation:
To move a quadratic function up/down, you change the value at the very end of the formula.
So instead of f(x)= x^2 + 1, you would do f(x)= x^2 - 2, to move it down 3. This would be the one in red.
The answer is 12 divide 168 by 14 to get 12.
