Answers and Step-by-step explanations:
(a)
We need to figure out the amount (or total cost) for each size candy given that they sell a certain number of each box. For the small box, we're given the cost is $4.70, while the large box is $7.00.
We buy x of the small box, so the total amount should be 4.70 * x, or just 4.70x. We buy y of the large box, so the total amount should be 7.00 * y, or just 7y.
So on the table, the top value should be 4.70x, and the bottom value should be 7y.
(b)
The total number of boxes sold was 45 boxes. Remember that x boxes were small and y boxes were large. Since the number of small boxes plus the number of large boxes is equal to the total of 45, we can write:
x + y = 45
(c)
The total cost was $269, so we can write this as the sum of the amounts that we found in part (a):
4.70x + 7y = 269
Answer:
Step-by-step explanation:
P(A) = Probability of drawing a green marble from a bag of two blue marbles, two green marbles, and three purple marbles
= 2 (green) / 7 (total of two, two and three)
= 2/7
P(B) = Probability of rolling a number less than 3 from a standard six-sided number cube
= 2 (1 and 2 less than 3) / 6 (1 through 6)
= 1/3
P(A) and P(B) are calculated to be two real numbers and do not depend on each other. So event A and B are independent.
