<u>Trigonometry</u>
[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = 8
Leg <em>b</em> = 4
Hypotenuse <em>c</em> = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [Pythagorean Theorem]: 8² + 4² = x²
- Evaluate exponents: 64 + 16 = x²
- Add: 80 = x²
- [Equality Property] Square root both sides: √80 = x
- Rewrite: x = √80
- Simplify: x = 4√5
Answer:
B
Step-by-step explanation:
11 13 18 19 22 25 29 32 37 37 38
find the median (25)
with 11,13,18,19,22 find the middle for that (18) Q1
with 29,32,37,37,38 find the middle for that (37)Q3
Q3-Q1
37-18=19
The correct answer is:
[B]: "

" .
__________________________________________________________Consider choice [A]: 
;
=

;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [A]" .
__________________________________________________________Consider choice [B]: 
;
=

;
= "-2" ; Yes!
→ Let us proceed with the final answer choice ;
__________________________________________________________Consider choice [C]:

;
=

;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [C]" .
