I believe your answer is D. 77.
When you need to identify elements in an informative manner. It also provides the essential information needed to balance chemical equations.
1500$/750tickets=2$
(2.50$+1.50$)/2=4/2=2$ <span>weighted average
this mean 50 50
750/2=375
</span>375 adult tickets and 375 children's tickets
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)
