Answer:
Not simplified: 12:30
Simplified: 1:5
Step-by-step explanation:
We have 12 League A cards and 30 total.
So, 12:30.
But we can divide by 6 and reduce it to its simplest form:
1:5
Answer:
(x - 2) • (4x + 1)
Step-by-step explanation:
The events are independent...because after the first pick, the card was replaced...that means the second pick has the same sample space. In other words, the first pick is not gonna affect the 2nd pick
8 football, 2 basketball...total of 10
P(1st pick is football) = 8/10 which reduces to 4/5
replace
P(2nd pick is basketball) = 2/10 which reduces to 1/5
P (both) = 4/5 * 1/5 = 4/25 = 0.16 <==
Using the cross product property on this proportion gives us the following equation:
20 (2x - 9) = 10 (9)
Use the distributive property and multiply
40x - 180 = 90
Add 180 to both sides
40x = 270
Divide 40 from both sides
x = 270/40
Simplify fraction
x = 27/4
This should be your answer. Let me know if you need any clarifications, thanks!
You should go by 0.001
so you can graph 0.001, 0.002, 0.003, and so on
