Answer:
The distance is 4.
Step-by-step explanation:
The shortest distance from the point (4,2) to the line y=-2, in this case, would be a straight line perpendicular to y=-2.
For each and every value of "x" on the line, y = -2. The shortest distance occurs at y(4) = - 2.
At this point the distance is:

The distance is 4.
20 degrees-> acute since less than 90
27 degrees-> acute since less than 90
133 degrees-> obtuse since more than 90
Answer:
20
Step-by-step explanation:
Answer:
-2.5
Step-by-step explanation:
Here in this question, we are interested in calculating the z-score for a student that had a particular mark at the test
To calculate the z-score, we need to use a mathematical formula
Mathematically;
z-score = (x - mean)/SD
From the question;
x = 76
mean = 86
standard deviation SD = 4
Plugging these values in the equation, we have;
z-score = (76-86)/4 = -10/4 = -2.5
