Answer: probability for 1st marble being green is 2/9 and 2nd marble being red is 1/4
Step-by-step explanation:
I hope this is correct. since there are 9 marbles and 2 of them are green, you do 2/9 which is 2/9 in its simplest form. And since you didn't put back the first marble there are 8 marbles left and 2 of them are red. You do 2/8 which in its simplest form is 1/4. I hope this helps
Remark
So CAB is a base 16 number? I hope that's correct. I'll treat it that way. If I am incorrect, please leave a note and I'll modify my answer accordingly.
Expand
A = 10 in decimal
B = 11 in decimal
C = 12 in decimal
B is the "units" value in decimal it is 11
A is the "tens" value or 12 place and in decimal you would get 12 * 10 = 120
C is the "hundreds" value or 12^2 place and in decimal you would get 144*12 =1728
Now you need to all all three results together. 11 + 120 + 1728 = 1850
Answer
(CAB)_16 = 1850 in decimal
So you've gotta have a variable representing the number of seconds between the time when you see lightning and the time when you hear thunder. I'm going to use <em>x.
</em>So equation:
<em /><em>x</em>/5=2
Solving:
you have to multiply both sides by five, so it becomes:
<em>x</em> = 10
so it's 10 seconds!
Step-by-step explanation:
5+ (3×4)=v
5+ (12)=v
v=17
