Answer:
3-pack= 135 cupcakes
6-pack= 270 cupcakes
9-pack= 405 cupcakes
Step-by-step explanation:
Let's say that 3-pack = a, 6-pack =b and 9-pack = c
The company’s leaders want to divide the cupcakes so that 3-pack, 6-pack and 9-pack packages produced are the same. This translate to an equation of:
a=b=c
The factory has 810 cupcakes in total. The equation will be:
a*3 + b*6 + c *9= 810
3a + 6b + 9c = 810
If we substitute the 1st equation into the second(we can put b=a and c=a), the equation will become
3a + 6b + 9c = 810
3a + 6(a) + 9(a) = 810
18a= 810
a=45
Using the first equation, we know that we have 45 packages of each kind.
If there are 45 packages of 3-pack, the number of cupcakes go into 3-package will be: 3*45= 135 cupcakes
If there are 45 packages of 6-pack, the number of cupcakes go into 6-package will be: 6*45= 270 cupcakes
If there are 45 packages of 9-pack, the number of cupcakes go into 9-package will be: 9*45= 405 cupcakes
Answer:
for the first card selected, just multiply the number of cards of that kind over the total amount (30) by the new number of cards of that kind over the new total amount (29)
sample space is 10+6+9+5=30
7. 10/30*9/29=0.103
8. 6/30*5/29
9. 9/30*6/29
10. 5/30*9/29
11. 21/30*20/29
12. 19/30*18/29
