Answer:
B
Step-by-step explanation:
3*5 is 15 and since its a negative 5 your answer will be negative
The mean doesn't have outliers, and if you're looking for a perfect middle of your data, the median is the best.

Answer:
3x +y -18 = 0
Step-by-step explanation:
The equation of the perpendicular line can be formed from the given equation by swapping the x- and y-coefficients, and negating one of them. The constant in the new equation will be the constant necessary to make the line pass through the given point.
__
<h3>swapped coefficients</h3>
3x +y +c = 0 . . . . . now both coefficients are positive
<h3>new constant</h3>
We want c such that the equation is satisfied at the point (x, y) = (9, -9):
3(9) +(-9) +c = 0
27 -9 +c = 0
c = -18
<h3>equation of perpendicular line</h3>
The equation of the desired line is ...
3x +y -18 = 0
Answer:
13°
Step-by-step explanation:
The trigonometric ratio formula can be used in calculating the angle of elevation (x°) of the sun, as the person makes a right angle with the ground.
The height of the person would be the opposite length = 6 ft, the shadow of the person would be the adjacent length = 26 ft
Therefore, according to the trigonometric ratio formula, we would calculate angle of elevation (x°) as follows:
x = tan-¹(0.2308)
x = 12.996
x ≈ 13° (to the nearest whole degree)
The angle of elevation of the sun = 13°
