Answer:
Reject the null hypothesis.
Step-by-step explanation:
n1 = 16
n2 = 21
S.V1 = 5.8
S.V2 = 2.4
= 0.05
= Population Variance 1 ≤ Population Variance 2
= Population Variance 1 > Population Variance 2
Test statistic value = 5.8 / 2.4 = 2.417
Degrees of freedom is n - 1
15 and 20
Critical value is
= 2.2
2.417 > 2.2
we reject the null hypothesis as the critical value is greater than the test statistic.
Answer:
2x(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
If F(3) then 3=x. So all you would do is substitute 3 in for x
Answer:
G
Step-by-step explanation:
Red marble probably currently: 12/32 = 3/8
Guess and check (using the multiple choice answers):
F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5
G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5
H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5
J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5
K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5
