Variance
<h2>
Step-by-step explanation:</h2>
The standard deviation is related to the variance. The standard deviation measures the variation or dispersion of a set of data and is represented by the Greek letter sigma 
, while the variance measures how far a set of numbers are spread out from their average value. The variance is obtained by squaring the standard deviation, so the variance can be found as 
Hello from MrBillDoesMath!
Answer: infinite solutions
Discussion: I did a double take on this one but the left hand is
a + 3 + 2a = 3a +3
and the right hand side is
-1 + 3a + 4 = 3a + (4-1) = 3a + 3
The left and right sides of the equation are identical for all "a", i.e. for infinitely many "a" values.

Answer:
0.6
Step-by-step explanation:
We know that there are 5 counters in total. 3 white and 2 black.
So we know that 3 out of 5 are white and 2 out of 5 are black.
Therefore the chance to get white is 3/5. And for black: 2/5.
We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)
And 2/5 = 0.4 (You can make it 4/10 to make it easier.)
Answering the question, you should put your cross/marker on 0.6
