Add the number and that should be your numbers

Answer:
That probability is 0.1838 or 18.4% or enter 18.4
Step-by-step explanation:
mean 35 sd 5
20 is 3 sd s to the left of the mean
30 is 1 sd to the left.
The empirical rule has 68% within 1 sd or 34% on one side
It has 95% within 2 sd or 47.5% on one side
It has 99.7% within 3 sd or 49.85% on one side
Therefore between 3 sd and 1 sd on one side is 49.85-34=15.85% or enter 15.9
mean of 48 sd 7
between 48 and 55 is between -1 and 0 sd or 34% enter 34. The last one doesn't seem to post easily:z=(x-mean)/sd or z< (1217-1481)/293 or z <-264/293 or -0.901,
That probability is 0.1838 or 18.4% or enter 18.4
Step-by-step explanation:
the graph should start on (-3) on the y-axis from there go up 2 and over one and that should be your next point on the graph.
you didn't show the graphs but to figure out if the color goes on the top or bottom... do
point (0,0)
plug into equation y<2x-3
(0)<2(0)-3
0<-3 (false)
wouldn't include the point (0,0)
hope this helps
