Relative frequency is frequency / total number
So if we know it lands yellow 28 and the total is 50
Relative frequency = 28/50 or 0.56 or 56%
9514 1404 393
Answer:
$68.00
Step-by-step explanation:
Let s represent the opening price. Then the closing price is ...
s - 3.25% × s = $65.79
s(1 -0.0325) = $65.79 . . . . collect terms
0.9675s = $65.79 . . . . . . . simplify
s = $65.79/0.9675 . . . . . . .divide by the coefficient of s
s = $68.00 . . . . . the opening stock price
the multiplication of fractions is very straightforward, numerators across and denominators across, now, let's firstly convert the mixed fraction to improper fraction.
