Given:
mean, μ = 11 lb
Std. deviation, σ = 2.1
Let x = the weight that separates the top 5% of the crop.
The z-score is
z = (x - μ)/σ
= (x - 11)/2.1
From standard z-table for normal distribution,
P(z=1.645) = 0.95
Therefore
(x - 11)/2.1 = 1.645
x - 11 = 1.645/2.1 = 0.7833
x = 11.783
Answer: 11.8 lb (nearest tenth)
I am pretty sure it is c because it inot a rihght triangle and or it does not have an hypoteneus
Multiply the first equation by 2 to give
10x + 2y = 20
2x - 2y = 4 Adding to elininate y
12 x = 24
x = 2
Plug x = 2 into 2x - 2y = 4
4 - 2y = 4
y = 0
so the answer is
(2,0)
