X+y=10
y=x-6
x + (x-6) = 10
2× - 6 = 10
2× = 4
x=2
(2, -4)
Answer:
There is not enough evidence to support the claim that the bags are under filled.
Step-by-step explanation:
Given :
Population mean, μ = 433
Sample size, n = 26
xbar = 427
Variance, s² = 324 ; Standard deviation, s = √324 = 18
The hypothesis :
H0 : μ = 433
H0 : μ < 433
The test statistic :
(xbar - μ) ÷ (s/√(n))
(427 - 433) / (18 / √26)
-6 / 3.5300904
T = -1.70
The Pvalue :
df = 26-1 = 25 ; α = 0.05
Pvalue = 0.0508
Since Pvalue > α ; WE fail to reject the Null and conclude that there is not enough evidence to support the claim that the bags are underfilled
Answer:
x=3+3y/2
Step-by-step explanation:
In base 12, A represents 10 and B represents 11. So
7B6A (base 12) = 7*12^3 + 11*12^2 + 6*12^1 + 10*12^0
7B6A (base 12) = 12,096 + 1,584 + 72 + 10
7B6A (base 12) = 13,762 (base 10)
