You have to power all the values in the brackets, like such:
(-3ab^3)^4 = (-3)^4 * a^4 * (b^3)^4 = 81*a^4*b^12
Answer: 367,750
Step-by-step explanation:
If the value increases by 6750 every year.
334000-280000 = 54000/8 = 6750
334000 + (6750 x 5) = 367,750

corrected question:A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random. For each of the following, find the probability that: a) both marbles are blue b) both marbles are the same color c)the marbles are different in color
Answer:
Step-by-step explanation:
<u><em>The probability was done with replacement.</em></u>
Probaility of an event happening
number of blue marbles= 2
number of green marbles=5
total number of marbles=7
(a) probability that both marbles are blue = pr(first is blue)*pr(second is blue)


(b)probability that both marbles are the same color =pr(first is blue)*pr(second is blue) + Pr(first is green)*Pr(second is green)



(c)Probability that the marbles are different in colors=pr(first is blue)*pr(second is green) + Pr(first is green)*Pr(second is blue)



Answer:
b
