- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cosθ = adjacent over hypotenuse
- Inverse Trig
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Angle θ = ?
Adjacent Leg = 13
Hypotenuse = 20
<u>Step 2: Find Angle</u>
- Substitute in variables [cosine]: cosθ = 13/20
- Inverse Trig: θ = cos⁻¹(13/20)
- Evaluate: θ = 49.4584°
Answer:
p = 1 ; q = 10,000
Step-by-step explanation:
Number of distinct colored balls = 10
Number of balls picked with replacement = 4
Probability = (number of required outcome / number of total possible outcomes)
Distinct picks :
P(1st) = 1 /10
P(2nd) = 1/10
P(3rd) = 1/10
P(4th) = 1/10
Expected Numbe of distinct color:
P(1st) * P(2nd) * P(3rd) * P(4th)
1/10 * 1/10 * 1/10 * 1/10
= 1/10000
p/q = 1/ 10000
p = 1 ; q = 10,000
C because if you look at it 1 1/4 it passes 2 1/4 so you know it’s gonna be 1 something and 2 1/2 is one after 2 1/4 so to get to 3 1/4 that would be 3 so 1 1/4 is the answer... if that make sense if not I can write it out to you and send a picture of how it’s worked out
