The answer should be D, nonverbal communication. One's willingness to do, say, or think something does not have to be communicated directly. It can be shown through other actions or behaviors.
Stock x and stock z and stock f are all 8% of 12%

dy\dx multiplied by dx\dt will give you dy\dt and dy\dx=-2 and dx\dt=3
Answer:
At a point X = 1.5 and Y = 4, the two lines will intersect
Explanation:
Given,
Two lines will intersect at the point with co-ordinates (X, Y) that will satisfy both the equations.
Hence,
y = 4x - 2 - Eq 1
y = 7 - 2x - Eq 2
Solving Eq 1 & 2, we get -
Eq 1 -Eq 2 will give
0 = 6X -9
6X = 9
X = 1.5
Y = 7 - 2*1.5 = 7-3 = 4
At a point X = 1.5 and Y = 4, the two lines will intersect
Answer:
A. Standard deviation is always a non-negative number.
Explanation:
The true statement about standard deviation is that, standard deviation is always a non-negative number.
A standard deviation is calculated by taking the square root of variance and as such the value of standard deviation is always a positive number and not a negative number.
Additionally, the variance of a sample population is calculated by the summation of all the squared distances obtained from the mean divided by the total number of samples. Hence, all the values of the variance are always positive (non-negative) numbers because they are squared. Consequently, the standard deviation would as well always be a non-negative number.
