Now; assuming X = no of complaints received in a week
Required:
To find P(77 < X < 120)
Using a Gaussian Normal Distribution (
108, 
= 20)
Using Z scores:
As a result X = 77 for N(108,20) is approximately equal to to Z = -1.75 for N(0,1)
SO;
Here; X = 77 for a N(108,20) is same to Z = 0.6 for N(0,1)
Now, to determine:
P(-1.75 < Z < 0.6) = P(Z < 0.6) - P( Z < - 1.75)
From the standard normal Z-table:
P(-1.75 < Z < 0.6) = 0.7257 - 0.0401
P(-1.75 < Z < 0.6) = 0.6856
Answer:
Point C occurs on the line x = 1
Point D occurs on the line y = -2
The intersection of both lines occurs at the point E = (1,-2)
The difference between the x coordinates of points D and E is 1 + 1/4 units
The difference between the y coordinates of points C and E is 1 unit
Let point F be the point that is 1/4 the distance from point C to point D
To find the x-coordinate F subtract the difference between the x coordinate of points C and E from the x-coordinate of C:
1 - (1 + 1/4) = -1/4
To find the y-coordinate of F subtract the difference between the y-coordinates of D and E from the y-coordinate of C
2 - 1 = 1
The coordinates of point F are (-1/4, 1)
Therefore, the y value of the point that is 1/4th the
Answer:
reflect across the y-axis; rotate 180° counterclockwise about the origin - first choice
The answer to the question is
