Answer:
Step-by-step explanation:
Plugin x = 0 & y = -2 in the LHS of the equation. After substituting, if you get the RHS, then this point is the solution of the equation.
x - 2y = 0 - 2*(-2)
= 0 + 4
= 4 = RHS.
(0,-2) is solution of the equation.
We are given
<span>μ > 1180
</span><span>α = 0.02
</span><span>σ = 201.71
x = </span><span>1198.79
n = 200
The null hypothesis is </span>μ ≤ 1180 while the alternative hypothesis is μ > 1180
The test statistic is 1.32 which means that the confidence internval is 98%. Getting the z-score
z = (x - μ) / σ
z = (1198.79 - 1180) / 201.71
z = 0.093
For a normally distributed population, the z-score of 0.093 has a p-value of
p = 0.46
For side length s, the area of a square is given by
... A = s²
Then the side length can be found to be
... s = √A = √(506.25 ft²) = 22.5 ft
The perimeter is the sum of the lengths of the four equal sides.
... P = 4s = 4·(22.5 ft) = 90 ft
Stevan will need 90 ft of fence to complete the job.
Actually, the answer is 1/12 because using the recorpial, you would do 2/3*1/8 getting 1/12
