Assume that the box contains 11 balls: 4 red, 4 blue, and 3 yellow. As in the text, you draw one ball, note its color, and if it is yellow replace it. If it is not yellow you do not replace it. You then draw a second ball and note its color.(1) What is the probability that the second ball drawn is yellow?
(2) What is the probability that the second ball drawn is red?

as 25 cent stamps and the same number of one-cent stamps as
2 cent stamps. How many stamps of each type did Yoko buy?
Answers
Answer:
- 30 of 25 cent, 10 of 14 cent, 60 of 2 cent
Step-by-step explanation:
- Note: it must be typo 10.70, changed to 10.10
Number of 25 cent stamps = x
Number of 14 cent stamps = y
Number of 2 sent stamps = z
- Total = $10.10 = 1010 ¢
- x = 3y
- z = 2x ⇒ z = 6y
Solving equation
- 25x + 14y + 2z = 1010
- 25(3y) + 14y + 12y = 1010
- 75y + 26y = 1010
- 101y = 1010
- y = 1010/101
- y = 10
The finding x and z
- x = 3*10 = 30
- z = 6*10 = 60

It take him to save at least $4,800 is 14 weeks.
Option (C) is correct.
To find the time it take him to save at least $4,800.
What is arithmetic?
The branch of mathematics dealing with the properties and manipulation of numbers.
Given that :
22 hours / week
1 hour = $15.80
So, if he works 22 hours per week he take total home pay is
=22 * 15.80
= $347.60
This means that he makes $347.60 per week.
If it take him to save at least $4,800 then
=4,800 divided by 347.60 is 13.8089758343
In decimal can't have 0.8 of a week, so round up. This means it will take him about 14 weeks.
So, it take him to save at least $4,800 is14 weeks.

(4x + 5)(5x - 3).
step-by-step explanation:
20x^2 + 25x - 12x - 15 by grouping:
Start with the expression:
20x^2 + 25x - 12x - 15.
Group the terms in pairs, like this:
(20x^2 + 25x) - (12x + 15).
Now, look for the greatest common factor (GCF) in each group:
In the first group
(20x^2 + 25x), the GCF is 5x because both terms are divisible by 5x.
So, factor out 5x: 5x(4x + 5).
In the second group (12x + 15), the GCF is 3 because both terms are divisible by 3.
So, factor out 3: 3(4x + 5).
Now, your expression looks like this:
5x(4x + 5) - 3(4x + 5).
Notice that both groups have the common factor (4x + 5).
Factor this out: (4x + 5)(5x - 3).
So, the factored form of 20x^2 + 25x - 12x - 15 is (4x + 5)(5x - 3)
