Answer:
3
Step-by-step explanation:
its the median, just see which one is in the middle by crossing out one dot on each side until you get to the middle
The answer will be B.
First you need to find the probability of the red marbles which is 5/12 because there is 5 marbles and if you add they up there would be 12. Then you find the probability of the green marbles which is 2/12. After that you need to multiply them. 5/12 × 2/12. Your answer will be 10/144 but then you can simply by 2.
So your answer will be 5/72.
Hope this helped.
Let <em>a</em> be the number in the 10s place and <em>b</em> in the 1s place. Then the original two-digit number is 10<em>a</em> + <em>b</em>.
The sum of the digits is 5:
<em>a</em> + <em>b</em> = 5
Subtract 9 from the original number, and we get the same number with its digits reversed:
(10<em>a</em> + <em>b</em>) - 9 = 10<em>b</em> + <em>a</em>
Simplifying this equation gives
9<em>a</em> - 9<em>b</em> = 9
or
<em>a</em> - <em>b</em> = 1
Add this to the first equation above:
(<em>a</em> + <em>b</em>) + (<em>a</em> - <em>b</em>) = 5 + 1
2<em>a</em> = 6
<em>a</em> = 3
Then
3 - <em>b</em> = 1
<em>b</em> = 2
So the original number is 32. Just to check, we have 3 + 2 = 5, and 32 - 9 = 23.
