Answer:
hey
Step-by-step explanation:
so chile anyways, stan you
The outcome A="At least one" means {1,2,3,4,5......n} where n is the maximum possible outcome.
The only other outcome (B) left (i.e. the complement of the above event "at least one") is (B)={0}.
Therefore, by Kolmogorov's second axiom, A and B are complements, and
P(A)+P(B)=1
therefore
P(A)=1-P(B), or in words,
Probability of outcomes of "at least one" is the complement of the outcome of "0" item.
Answer:
Step-by-step explanation:
3/4 inch to 1 mile = 1 3/4(or 7/4 in) to x miles
make a proportion
(3/4) (7/4)
-------- = ------- cross multiply
1 x
(3/4)(x) = (7/4)(1)
3/4x = 7/4
x = (7/4) / (3/4)
x = 7/4 * 4/3
x = 7/3 or 2 1/3 miles <===
All angles are the same and all side lengths are equal/congruent

- [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°
