C because if the denominator equals x-2 that means that the horizontal asymptote happens at x=2. And because the numerator and denominator have the same degree then you divide leading coefficients to get the vertical asymptote at y=-2

Find the distance between (2,7) and (-6,-2)

stepladder [879]

Answer: $\sqrt{145}$

Step-by-step explanation:

1. use the distance formula!

$distance = \sqrt{(x_{2} - x_{1})^{2} +{(y_{2} - y_{1})}^2$

2. then using the distance formula with (2, 7) and (-6, -2) you get...

$distance= \sqrt{2 -(-6)^2 +(7 - (-2)^2}$

$distance= \sqrt{8^2 +9^2}$

$distance= \sqrt{64 +81}$

$distance= \sqrt{145}$

$\sqrt{145}$ is the simplest radical form

For a data consisting of 9 observations, the sum of 9 values is 360 and the sum of squares of deviation taken from the mean is 2

maxonik [38]

Answer:

4 ; 32

Step-by-step explanation:

Given that :

Number of observations, n = 9

Let observations = X

ΣX = 360

The mean, (m) is calculated using the formula :

m = ΣX / n

m = 360 / 9

m = 4

Σ(X - m) = 288 (sum of square of deviation )

Variance is calculated using the formula :

[Σ(X - m) / n]

Variance = Sqrt(288 / 9)

Variance = 32
