Answer:

17.11%

Step-by-step explanation:

since 43.2 months is the mean, and the standard deviation is 7.7 months

that means if we take the z score:

z=(36-43.2)/7.7

now that we know how many standard deviations you are away from the mean: -0.9351

using the zscore table you can find the proportion, or you can use the calculator if you have one that can do that.

you get 0.1711 which in percentages is 17.11%

Answer:

16) $y=\frac{1}{4}x +5$

17) y = -x - 4

18) y = -2x - 1

19) y = -2x

20) $y=\frac{-5}{3} -3$

Step-by-step explanation:

With the two points you find the slope using $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
