Answer:
Option a is right
Step-by-step explanation:
Given that as part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at random concerning their monthly credit card balance.
Sample average = 2573
Variance = 4252
Sample size = 35
STd deviation of X = ![\sqrt{4252} \\=65.21](https://tex.z-dn.net/?f=%5Csqrt%7B4252%7D%20%5C%5C%3D65.21)
Score of student selected at random X=1700
Corresponding Z score = ![\frac{1700-2573}{65.201} \\=-13.38](https://tex.z-dn.net/?f=%5Cfrac%7B1700-2573%7D%7B65.201%7D%20%5C%5C%3D-13.38)
Rounding of we get Z score = -13.4
option a is right
To create a line that is perpendicular to the one given, completely invert the slope.
y = -3/2x + 9
The answer to your question is 175.84 bc C=2(pi)r and if you plug in the numbers it equals 175.84... B hope that helped :)
