Answer:
99
Step-by-step explanation:
The mean = 90 days
standard deviation = 20 days
P(Z < z) = 68 %
getting the value of z-score from the standard normal table of 0.68
z = 0.47
P(Z < 0.47) = 0.47 * 20 + 90 = 99
Step-by-step explanation:
I used a co-ordinate graph and place the ticket booth at the origin then I chose difference of four but you can choose any and place three events equidistant from the origin by using the X- and Y- axis to easily determined a distance of 4 from the origin .
(0-4, 0) =( 4,0)
(0+4, 0) = (4 ,0)
(0, 0+4) = (0, 4)
if the both are placed first u would need to find the equation of a circle that contains all three points and place the booth at centre
you do this by creating the system of 3 equations inputting the x,y coordinates of each booth and solving for h,k,r
equation of a circle (X-H) 2 +( Y-K) 2 = r2
Hope It helps
:DD have a nice day
Answer:
-3/4x
Step-by-step explanation:
Down 3, right 4. We know it's negative because it's declining, and going down till you reach the x-coordinate of the point gives us -3, and going right 4 units to the location of the point.
