3 - 7 = -4
Why?
7 is a bigger number than 3 which makes the answer a negative number.
-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9
that is a number line and if you start from 3 and go back 7 spaces it would be -4.
In conclusion,
-4 is the absolute value of 3 - 7.
A graphing calculator finds the regression line to be
y = 5.5x + 52
Answer:
Percent error = 4.29%
Step-by-step explanation:
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
Given the following data;
Experimental value = 67
Theoretical value = 70
Substituting into the equation, we have;
Percent error = 4.29%
Replace x with 10 and simplify the fraction.
40/10 = 4/1 = 4
The answer is 4
So the first one is -0.5 and second is -0.5 the third one is -0.5 and the fourth is -0.25 so I would say that is D
