Answer:

0.5 or 50%

Step-by-step explanation:

For any given value of 'x' representing the time between arrivals of two customers. If 0 < x <120, then the cumulative distribution function is:

\frac{x-0}{120-0}=\frac{x}{120}

Therefore, the probability that the time between the arrivals of two customers will be more than 60 seconds is determined by:

P(X>60) = 1 -\frac{60}{120}\\P(X>60) = 0.5

The probability is 0.5 or 50%.

Answer:

  D.  $432.84

Step-by-step explanation:

The average daily balance is the weighted sum of the balances. The weight in each case is the number of days the account had that balance.

  adb = (7×745.00 +10×585.15 +7×245.20 +7×90.75)/(7+10+7+7)

  = 13,418.15/31

  = 432.84
