Answer:

0.2308 or 23.08%

Explanation:

Mean (μ) = $12.50

Standard deviation (σ) = $3.25

Assuming a normal distribution, for any given fare X, the z-score is calculated as:

z = \frac{X-\mu }{\sigma}

For X = $15.00, the z-score is:

z = \frac{15.00-12.50 }{3.25}\\ z=0.7692

A z-score of 0.7692 corresponds to the 77.91-th percentile of a normal distribution. Therefore, the probability that a fare exceeds $15.00 is:

P(X>\$15.00) = 1-0.7692 = 0.2308

The probability that a specific fare will exceed $15.00 is 0.2308.

Nataly_w [17]

Answer:

The stockholders that purchase the stock on the record date or any date after the ex-dividend date, will not be entitled to receive the dividend. In this case, the ex-dividend date was July 11th, and both Ted and Kate purchased the stocks before that date.
  3. The date of payment: the actual date when the dividends are distributed, in this case, August 1st.
