2. He can do 5 times 3 to get to the 15th shape and then say 2 more to get the 17th shape.
(The 17th shape would be triangle)
A = 1/2 (base * height)
A = 1/2 [(x^2 + 2x + 4)*(<span>2x^2 + 2x + 6)]</span>

Answer:
The minimum score an applicant must receive for admission is 392.
Step-by-step explanation:
Let the minimum score required be 'x₀'.
Given:
Mean score (μ) = 500
Standard deviation (σ) = 100
Percentage required for admission, P > 86% or 0.86
So, we are given the area under the normal distribution curve to the right of z-score which is 86%.
The z-score table gives the area left of the z-score value. So, we will find the z-score value for area 100 - 86 = 14% or 0.14
So, for value equal to 0.1401, the z-score = -1.08
Now, 
So, we find x₀ using the formula of z-score which is given as:

Therefore, the minimum score an applicant must receive for admission is 392.
