<span>The minus sign of the z-score shows that the score is below the mean.
6 points below the mean means the difference of the score and mean is -6
z = (X-Mean)/SD
-0.50 = -6 / SD
SD = -6/-0.50 = 12
The population standard deviation = 12</span>
This triangle can be classified as an Acute Scalene Triangle.
It is an Acute triangle because all of its sides are acute (less than 90 degrees)
It is a Scalene triangle because all of its sides are of different lengths.
To find the missing angle degree we must subtract 61 and 78 from 180. We subtract them from 180 because all angles of a triangle add up to 180 degrees.
180 - 61 - 78 = 41.
So the missing angle (x) = 41 degrees.
Hope I helped!
Answer:
3
Step-by-step explanation:
the roots of a polynomial are the points on the x-axis where the polynomial intersects the x-axis
As can be seen from the graph there are 3 points of intersection.
roots are x = - 6, x = - 2 and x ≈ - 1
