Answer:
this would represent a strong negative
Step-by-step explanation:
on a correlation line you have strong negatives,weak negatives,none,weak positives, and strong positives.Since the coefficient is a hand negative, focus on the left side. A weak negative is -0.5 greater than or equal to so since -0.94 is less than -0.5 it advances on to the next category of the correlation line, thus resulting in the correlation coefficient to be a strong negative.
Width = 45 inches
Height = 36 inches
Area = 45 • 36 = 1620 inches squared
The resultant force in this item, is that which connects the heads of the magnitude of the given vectors. The magnitude of the resultant force can be calculated through the Pythagorean theorem which states that the square of the resultant force should be equal to the sum of the squares of the smaller forces. That is,
A² + B² = C²
Investigating the vector values,
A² + B² = (3.5 lb)² + (6.2 lb)² = 50.69 lb²
C² = (9.1 lb)² = 82.81 lb²
Since the Pythagorean theorem is not satisfied by the given set of forces then, the forces are not in right angle.
The answer to the question is letter C.
Answer:
f(12) = - 20
Step-by-step explanation:
To evaluate f(12), substitute x = 12 into f(x), that is
f(12) = - 2(12) + 4 = - 24 + 4 = - 20
