90 points for 2 multiple choice ! the steps below show the incomplete solution to find the value of x for the equation 5x − 2x − 3 = −2 + 17: step 1: 5x − 2x − 3 = −2 + 17 step 2: 5x − 2x − 3 = 15 step 3: 3x − 3 = 15 which of these is most likely the next step? 3x = 5 3x = 12 3x = 18 3x = 45 how many solutions can be found for the equation 3x − 2 = 3x + 5? zero one two infinitely many

The graph below could be the graph of which exponential function?

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
