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

When the outliers are removed how does the mean change? Dot plot with one on 18, 2 on 38, one on 40, 3 on 44, one on 46, one on
Vitek1552 [10]
18,38,38,40,44,44,44,46,48....
the mean with the outlier (18) included is : 360/9 = 40

38,38,40,44,44,44,46,48
the mean with the outlier (18) excluded is : (360 - 18) / 9 = 342/9 = 38

so when the outlier is removed, the mean is 2 points less
