The answer is No because the sample is not representative of the whole population. The standard deviation of the sample is not a good estimate of the variation of the salaries of the TV personalities in general because a single sample is not counted as a whole. Standard Deviation is a quantity that is calculated to indicate the extent of deviation of the population or group as a whole. Standard deviation also represented by the symbol σ means sigma in Greek letter or s in Latin letter. It is also the measurement of a set of data values that are used to quantify the amount of variation.
The side AB measures option 2.
units long.
Step-by-step explanation:
Step 1:
The coordinates of the given triangle ABC are A (4, 5), B (2, 1), and C (4, 1).
The sides of the triangle are AB, BC, and CA. We need to determine the length of AB.
To calculate the distance between two points, we use the formula 
where (
) are the coordinates of the first point and (
) are the coordinates of the second point.
Step 2:
For A (4, 5) and B (2, 1), (
) = (4, 5) and (
) = (2, 1). Substituting these values in the distance formula, we get

So the side AB measures
units long which is the second option.
The following are the choices on this question:
A.6
B. 39
C. 26
D. 12
The answer is option D. 12.
Check this out:
S=n² + n
S= 12² + 12
(you can get the square of 12 by multiplying 12 by itself: 12 × 12)
S=144 +12
S=156
ANSWER: y=7 is the equation Of the line that passes to through the point (-2,7) and Has a slope of zero.
Answer:
y - 7 = 4(x + 3)
Step-by-step explanation:
Write the equation of a line using the point slope formula. Substitute m = 4 and the point (-3,7) in the formula.
