In standard normal distribution, the cutoff for the 95th percentile is about z\approx1.64. So the cutoff height would be x such that

\dfrac{x-180}7=1.64\implies x\approx191.48

cm.

Using the Principle of Mathematical Induction, prove that . n ^2 − n is even for n ≥ 1​
Tamiku [17]

Base case: if <em>n</em> = 1, then

1² - 1 = 0

which is even.

Induction hypothesis: assume the statement is true for <em>n</em> = <em>k</em>, namely that <em>k</em> ² - <em>k</em> is even. This means that <em>k</em> ² - <em>k</em> = 2<em>m</em> for some integer <em>m</em>.

Induction step: show that the assumption implies (<em>k</em> + 1)² - (<em>k</em> + 1) is also even. We have

(<em>k</em> + 1)² - (<em>k</em> + 1) = <em>k</em> ² + 2<em>k</em> + 1 - <em>k</em> - 1

… = (<em>k</em> ² - <em>k</em>) + 2<em>k</em>

… = 2<em>m</em> + 2<em>k</em>

… = 2 (<em>m</em> + <em>k</em>)

which is clearly even. QED

Simplify the expression and show work.
nasty-shy [4]

Answer:

72/149

Step-by-step explanation:

Just to clarify, the curly braces mean the same thing as normal parenthesis.

(12 + 5^2) = (12 + 25) = 37

(-7-15)^2 = (-22)^2 = 484

6^3  = 216

(12 + 5^2) - (-7-15)^2 = 37 - 484 = 447

6^3 / ((12 + 5^2) - (-7 - 15)^2) = 216 / 447 = 72/149

A rectangular
igor_vitrenko [27]
A = length x width

15,000 = (w + 30) x w
15,000 = w^{2} + 30w
0 = w^{2} + 30w - 15,000

Use quadratic formula to find that  w= -15 + or - 5\sqrt{609}. Because distance cannot be negative, the width is -15 + 5\sqrt{609}meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
