salaries of nurses in southern california are normally distributed with a mean of $6250 and a standard deviation of $250. what i

cestrela7 [59]

Step-by-step explanation:

z-score of X = 6150

$\frac{6150 - 6250}{250} = - 0.4 \\$

z-score of X = 6350

$\frac{6350 - 6250}{250} = - 0.4$

P(X<6150) + P(X>6350)

=P(z<-0.4) + P(z>-0.4)

=0.3446+0.3446

=0.6892

The following graph shows data regarding the population of a town in thousands. At what rate was the population changing?

Elina [12.6K]

Notice those two points on the "linear graph", the first point is at (1965 , 140) and the second point is at (1990 , 100).

the rate or average rate of change, namely the slope will then be

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 1965}} &,&{{140}}~) 
% (c,d)
&&(~{{ 1990}} &,&{{ 100}}~)
\end{array}
\\\\\\
% slope = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{100-140}{1990-1965}\implies \cfrac{-40}{25}\implies -\cfrac{8}{5}$
