Answer:
Mean
Step-by-step explanation:
The mean is usually used when the dot plots, or histograms, are symmetrical and have no outliers.
Plug x = 4 into the equation and solve for y
3(4) - y = 4
y = 8
The point is (4, 8)

Answer:
cot(θ) = 4/5
Step-by-step explanation:
In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...
(x, y) = (r·cos(θ), r·sin(θ))
From the various trig definitions and identities, we also know that ...
cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y
For the given (x, y) = (-4, -5), the cotangent is ...
cot(θ) = -4/-5 = 4/5
9 + 7 - 10 = 6 I don’t see the choice above but this is the correct answer.
