The easiest way is to write down the length of each side, and then add up
the three numbers.
In fact, that's the ONLY way to find the perimeter. If anything else needs to
be done, that's usually because you don't know all three lengths yet, and
you have to find a missing length. Once you accomplish that, you ALWAYS
find the perimeter by adding them up.
Where the variance is 0.32, the mean is 0.40, and there are provided sets of probabilities, the standard deviation will be 0.566.
<h3>What is standard deviation?</h3>
The average degree of variability in your dataset is represented by the standard deviation. It reveals the average deviation of each statistic from the mean. In general, values with a high standard deviation are spread out from the mean, whereas those with a low standard deviation are grouped together close to the mean.
Here,
mean=0.4
variance=(Xn-mean)².P(x)n
=(0-0.4)²*(0.64)+(1-0.4)²*(0.32)+(2-0.4)²*0.04
variance=0.32
Standard deviation=√(variance)
=√0.32
=0.566
The standard deviation will be 0.566 where variance in 0.32 and mean is 0.40 and given sets of probability.

Answer:
8x+2
Step-by-step explanation:
Calculator estimates 4/13 is .3076 and 3/10 to be .3 so 4/13 is larger
3/10 is rational because decimal can be predicted unlike 4/13 which keeps going
