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
Answer:
y = 15
Step-by-step explanation:
x + y + z = 45 → (1)
Given
y = (x + z)
Multiply both sides by 2 to clear the fraction
2y = x + z ← substitute into (1)
2y + y = 45
3y = 45 ( divide both sides by 3 )
y = 15
Answer:
I think the answer should be Mat A cause it has more space.
Your answer would be 746.5.
