In a circle centered at O, there are two chords, AC and EF, both measuring 9.07.
OD and OB are the perpendiculars from the center O to the chords AC and EF, indicating their distance from the center.
The theorem concerning circles states that chords of equal length are equidistant from the center.
This means that OD and OB are equal.
Thus, the correct answer is Option A.
The full query is as follows: A sports store manager had a ski set sold at a specific price, implementing markdowns that led to a one-day sale price of $325. Determine the original selling price considering a 10% markdown followed by an additional 30% discount.
Let X represent the numbered marbles.
P(21≤ X ≤27) = 0.4332

P( 0 ≤ z ≤ 6/σx) = 0.4332; for this case, Z stands for the z-score
1.5 = 6/σx
solving for σx gives us 4
