Answer:
w= -0.163265306122449
Step-by-step explanation:
49w = -8
divide both sides by 49
w= -8/49 = -0.163265306122449
check answer by multiplying -0.163265306122449 by 49
49 * -0.163265306122449 = -8

yes it is i got a hundered on my test
Answer:
0.101
Step-by-step explanation:
Given that :
Standard deviation, s = 0.2
Sample variance, s² = 0.0653
Sample size, n = 10
Population variance = σ² = 0.04
We use the Chi square distribution :
(n - 1)s² / σ²
For P(s² ≥ 0.065)
(n - 1)s² / σ² = (10 - 1)*0.0653 / 0.04
(n - 1)s² / σ² = 0.585 / 0.04 = 14.625
P(s² ≥ 14.625) = 0.101 ( chi squee calculator).
