<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: Identify</u>
Leg a = 24
Leg b = 7 in
Leg c = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [Pythagorean Theorem]: 24² + 7² = x²
- Evaluate exponents: 576 + 49 = x²
- Add: 625 = x²
- [Equality Property] Square root both sides: 25 = x
- Rewrite/Rearrange: x = 25
y=4x-3(4,1)x2 (2-0) perpedkdkke
17+3=20
740/20=37 Classes
37 classes x 3 faculty members=111
Y<span>≥18
You want to get the y only on one side of the equation. To get rid of the -6 you have to add 6 to both sides to even out the equation.

+6 +6

Relative frequency is the number of times that the train is late between the total of journeys, so only multiply 0.15*100 =15 times
