The lifespan of a pair of shoes is normally distributed with a mean of 24 months and a standard deviation of 6 months. What is the
probability that a new pair of shoes won't last longer than 18 months?
a)8%
b)50%
c)23%
d)16%
e)34%

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

there is no points to select.

step-by-step explanation:

noncoplanar points are points that do not lie on the same line.
