1. Normal Distribution --> Z ~ (0,1^2)
2. Use normalcdf(lower bound, upper bound, μ, σ) function on a graphing calculator
P(Z≥103.53) = normalcdf(103.53, 1e99 [default], 80, 13)
P(Z≥103.53) ≈ 0.03
3. μ+σ ≈ 13.59% According to Z-distribution chart
80+13=93
So about 93 exceed only the top 16% (estimated answer not exact)
Answer:
7
Step-by-step explanation:
1. Subtract the 4x on both sides = -14 = -2x
2. Divide -2 on both sides to get -14/-2 = x
3. -14/-2 = 7 so 7 = x
The answer to the question is 21

Answer:
Width of the rectangular banner is 
ft.
Step-by-step explanation:
Area of the rectangular banner = 
square feet
= 
square feet
Area of rectangle is given by,
Area = Length × Width
Length of the banner = 
feet
From the formula,
W = 
= 
= 
= ft
Therefore, width of the rectangular banner is ft
