The outlier would be the one with (17, 72) coordinates. If interpreted, the child is 17 years old and the number of pages the child reads in a week is 72. He appeared the outlier because his data was too far from the pattern of data relative to the sample.
Answer:
31
Step-by-step explanation:
since it is perpendicular line you have to change thing signs of the equation.
x y
(-1,4)
replace the (-1) with x and (4) with y
y=1/2x+b
4=1/2(-1)+b
4=-1/2+b
4+1/2=b
9/2=b
therefore, the perpendicular line is y=1/2x+9/2
Answer:
100N
Step-by-step explanation:
BC 80+20=100. THEN ADD THE N AND YOU GET 100N
Answer:
v ≈ (3.28512, 20.74146)
Step-by-step explanation:
v = 21(cos(81°), sin(81°))
v ≈ (3.28512, 20.74146) . . . . (x, y) components
The notation varies among authors. The vector can be written as ...
(r, θ) = (21, 81°)
r∠θ = 21∠81°
r cis θ = 21 cis 81°
v = 21·e^(i·9π/20)
(x, y) ≈ (3.28512, 20.74146)
v = 3.28512i +20.74146j . . . . perhaps this is the vector notation you want (i and j are unit vectors in the x- and y-directions, respectively)
