Help PLEASE! Review the equation used in writing a partial fraction
decomposition.
Which system of equations can be used to determine
the values of A and B?
- 15x + 10
(5x - 2)
А B
5x - 2 (5x - 2)2
+
5A = - 15
2A + B = 10
SA = -15
-24 + B = 10
SB = -15
A-2B = 10
5B = -15
A + 2B = 10

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
