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)



The x-coordinate of the vertex represents the LOWEST horizontal DISTANCE from the left side of the ride.
<span>Substitute the value of y which is 125,000 in the equation x - 62,500 = 0.25y. The product of 0.25 and 125,000 is 31,250. Transpose 62,500 to the other side of the equation. Add 62,500 to 31,250. The number of votes Maya received which x represent is 93570,</span>
Answer:
$95.48 was his commission
Step-by-step explanation:
First we need to find what the retail cost of the chest is. If it's marked up 150%, we use 763.84 + 1.5(763.84) which gives us a retail price of $1909.60. If Ben makes 5% on the sale as his commission, then we take 5% of 1909.60 which, in algebraic terms, looks like this: .05(1909.60) which is $95.48
Answer:
