Answer:
Z- score is - 2.21
Step-by-step explanation:
Given that,
Mean = 21.1
Standard deviation = 4.8
sample size (n) = 50
sample mean = 19.6
we want to find, z-score corresponding to mean of 19.6
Z = =-2.21
Z-score is -2.21

Answer:
y = 3/4x +4
Step-by-step explanation:
From point A to point B, you show a rise of 3 units and a run of 4 units. (The rise is the difference in height of the first two squares; the run is the side length of the first square.) The ratio rise/run = 3/4 is the slope of the line you want.
The upper-left corner of the first square is the y-intercept of the line (4). So, in slope-intercept form, the equation of the dotted line is ...
y = mx + b . . . . . m = slope; b = y-intercept
y = 3/4x + 4
