Step-by-step explanation: Probability indicates that the event <u><em>WILL </em></u>occur. Odds (in ratio) on the other hand indicates and reflects a prospect that there will be a non-occurrence of the events. It all depends on the connotation.
You need to know atleast 2 of three sides from a triangle, or 1 side and 1 angle of a triangle. Then you can use trigonometry to find the angle needed.
Answer:
22n - 11
Step-by-step explanation:
An = a1 + (n-1)*d
n = term to find = 30
a1 = first term = 20
d = common difference = 2
a30 = 20 + (30 - 1) * 2
a30 = 20 + 29 * 2
a30 = 20 + 58
a30 = 78
sn = (n (a1 + a30)) / 2
s30 = (30(20 + 78) / 2
s30 = (30(98) / 2
s30 = 2940/2
s30 = 1470 <===
= 1 3/20 or in decimal it's 1.15
hope this helps
