X=25x−3=13−3x
5x+−3=13+−3x
5x−3=−3x+13
Step 2: Add 3x to both sides.
5x−3+3x=−3x+13+3x
8x−3=13
Step 3: Add 3 to both sides.
8x−3+3=13+3
8x=16
Step 4: Divide both sides by 8.
8x8=168
x=2

Step-by-step explanation:
Answer: 8.3
Step-by-step explanation:
To find the variance, you want to find the mean of the data.
Now that we have the mean, we find the difference between each data point and the mean.
3-5=-2
3-5=-2
8-5=3
1-5=-4
9-5=4
6-5=1
With the difference, you square each and find the average.
(-2)²=4
(-2)²=4
3²=9
(-4)²=16
4²=16
1²=1
The variance is 8.3.
There are 12 face cards in a deck, and one you draw the first face card there will be 11 left so:
(12/52)*(11/51)=132/2652=11/221
