Use relative frequencies calculated for rows or columns to describe possible association between the two variables, Jeremy asked a sample
of 40 8th grade students whether or not they had a curfew. He then
asked if they had a set bedtime for school nights, He recorded his data in
this two-way frequency table. Is there evidence that those who have a

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock

the answer is 9 because the question is telling how much it be together.
