Step-by-step explanation:
Graph out the equation and look for the x and y intercept.
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
5/9 * 3/2 = (5*3)/(9*2) = 15/18 = 5/6
