Answer:
The probability of picking a purple marble, and then, not replacing picking an orange marble is approximately 20%
Step-by-step explanation:
First we know that there are 20 marbles in the bag, so the probability of picking a purple marble is 11/20. If we take a purple marble out, there will only be 19 marbles remaining in the bag. So the probability of picking an orange marble would be 7/19. Now, all we need to do is multiply the 2 fractions, and we will get 77/380 which equals to which is approximately 20% .

Answer:
6536.25
Step-by-step explanation:
Given that :
Number of friends = 4
Cost of movie ticket = 725 each
At concession stand:
Pop corn = 850
Number of popcorn = 2
Large soda = 575
Number of large sodas = 3
Discount given = 15%
Amount spent on movie ticket :
725 * 5 = 3625
Amount spent at concession stand :
Cost of popcorn + cost of large soda
(850 * 2) + (575 * 3) = 3425
15% discount on purchase :
Discount = ((1-0.15) * 3425) = 2911.25
Total amount spent :
3625 + 2911.25
= 6536.25
Answer:
27.2 cm
Step-by-step explanation:
14 cm / 2.5 = 5.6 cm, and
20 cm / 2.5 = 8 cm.
Then the new perimeter would be P = 2L + 2W, or, in this case:
P = 2(8 cm) + 2(5.6 cm) = 27.2 cm
