After the 3rd pick we have: 4 white, 3 red and 8 black marbles.
The probability that the 4th marble is black is:
P ( Black ) = 8 / 15 = 0.5333
After the 4th pick we have: 4 white, 3 red and 7 black marbles.
P ( Red or Black ) = 10 / 14 = 5 / 7 = 0.7143

Answer:
C. 7h + 50 > 99
Step-by-step explanation:
She earns <u>more</u> than $99, so you know that the sign will be > (more than).
h is the number of hours, so to find how much she earns for working h hours at $7/hour, you multiply h by 7 --- 7h
She also earns an additional $50, which will be +50.
Therefore, the equation is: 7h + 50 > 99
Hope this helps :D

Answer: 13 days</h3>
====================================================
Explanation:
Count the number of leaves marked in green.
- Row One: 2 leaves (1 and 8)
- Row Two: 3 leaves (3, 6, and 9)
- Row Three: 5 leaves (2, 3, 4, 6, 7)
- Row Four: 3 leaves (1, 6, and 8)
There are 2+3+5+3 = 13 leaves total. This represents tickets were sold on 13 days.
Each stem and leaf combines to form a different ticket count. For instance, the stem of 1 and leaf of 8 combine to get the value 18. So 18 tickets were sold on that particular day.
If you looking for the amount of beans
25 = 16.75 + 1.50×b
25-16.75 = 1.50b
8.25 = 1.50b
8.25/1.50 = b
b = 5.5
