Answer:
x = 
Step-by-step explanation:
Add 8 to both sides;
4|4x - 3| = 4 4|4x - 3| = -4
Divide both sides by 4;
4x - 3 = 1 4x - 3 = -1
Add 3 to both sides;
4x = 4 4x = 2
Divide both sides by 4;
x = 1 x = 
8x2+6x-2
I think! because 8,6, and 2 are all divisible by 2
and 3. Factor the quadratic
2(4x-1)(x+1)
Answer:
we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.
Step-by-step explanation:
H0 : μ = 582
H1 : μ < 582
Test statistic :
T = (xbar - μ) ÷ σ/√n
Xbar = 515 ; n = 20 ; σ = 120
T = (515 - 582) ÷ 120/√20
T = -67 / 26.832815
T = 2.50
Pvalue at t score = 2.50 ; df = 19 is 0.0187
At α = 0.0187
Pvalue > α ; Hence, we fail to reject the Null
Hence, we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.
Answer:
Perimeter = 36m
Step-by-step explanation:
Area = l x w
65m = 13m x w
5m = w
Perimeter = 2(l + w)
Perimeter = 2(13m + 5m)
Perimeter = 36m
