To find the curve of best fit, you will need to do exponential regression. Press STAT, then right arrow to highlight CALC, and then press 0:ExpReg . The correlation coefficient is r, which is 0.994 in this case. That means that the equation is a 99.4% match to the data.
Answer:
x = 128
Step-by-step explanation:
Adjacent angles - Angles right next to each other. They share a common vertex
Vertical angles - angles that are vertically aligned with each other.
The angle that has a measure of 128 degrees and x are vertical angles
If you didn't know vertical angles are congruent so because one angle equals 128 degrees the other equals 128 degrees
x = 128
A parabola graph is a graph where the line is curved. A linear graph is a graph where the line is straight.
Answer:
x=39, y = 5 and z = -4.
Step-by-step explanation:
x + y - 5z = 24
y + z = 1
z = -4
Plug z = -4 into the second equation:
y + -4 = 1
y = 5.
Now plug x = -4 and y = 5 into the first equation:
x + 5 - 5*4 = 24
x = 24 - 5 + 20
x = 39.
