Mathematics

First you would distribute the -12 to x and 5.
You would get -12x-60=144. Now solve for x.
Add 60 on both sides. (Do the inverse)
You get -12x=204
Then divide by -12 on both sides.
Answer: x=-17

First, you distribute -12 to the (x+5) leaving you with the equation 144 = -12x-60. Then you cancel out the 60 by adding 60 to both sides of the equation. After that your equation will be 204 = -12x. Last you divide both sides by -12 to cancel out the 12 and get your answer (x = -17).

Find the sample variance and standard deviation of: <br><br>21, 12, 3, 9, 11<br><br><br>s2=?
olga nikolaevna [1]

Answer:

42. 2

6.496

Step-by-step explanation:

Given the data :

21, 12, 3, 9, 11

Variance :

S² = Σ(x - m)² ÷ (n - 1)

n = sample size = 5

m = sample mean = Σx / n

m = (21 + 12 + 3 + 9 + 11) / 5

m = 11. 2

(21-11.2)² + (12 -11.2)² + (3 - 11.2)² + (9-11.2)²

+ (11-11.2)² / (5 - 1)

S² = 42.2

Standard deviation, s = sqrt(42.2) = 6.496
