419.1 is greater than 419.099, since there is a number on the tenths place of 419.1, where as the latter does not.

And, when you round 419.099 up to the nearest tenth, you get 419.1.

The variance can never bea.zerob.larger than the standard deviationc.negatived.smaller than the standard deviation

MrRa [10]

Answer:

c.negative

True, by definition since the variance take in count the differences around the mean squared, then we can't have a negative value for a sum of square values.

Step-by-step explanation:

We need to remember that the variance is a measure of dispersion for a dataset respect to a measure of central tendency called the mean. The mean is defined as:

$\bar x = \frac{\sum_{i=1}^n X_i}{n}$

And the population mean is given by:

$\mu= \frac{\sum_{i=1}^n X_i}{N}$

The population variance is defined by:

$\sigma^2 = \frac{\sum_{i=1}^n (X_i -\mu)^2}{N}$

And the sample variance is defined as:

$s^2= \frac{\sum_{i=1}^n (X_i -\bar x)}{n-1}$

Now if we analyze the options we have this:

a.zero

False, if all the values are the same then the mean would be the same to the values and the difference between each value and the mean would 0 and indeed the variance would be 0.

b.larger than the standard deviation

False, if the population standard deviation is $\sigma=2$ then the variance would be $\sigma^2 = 4$ and as we can see is higher than the standard deviation

c.negative

True, by definition since the variance take in count the differences around the mean squared, then we can't have a negative value for a sum of square values.

d.smaller than the standard deviation

False, if the population standard deviation is $\sigma=0.1$ then the variance would be $\sigma^2 = 0.01$ and as we can see is lower than the standard deviation

a plane is passed through a parallelepiped, cutting all the lateral edges and forming a right section which is a square. If the

velikii [3]

There are several information's already given in the question. Based on those given information's the answer can be easily deduced.
Lateral area of the solid = 216 cm^2
Lateral edge of the solid = 9 cm
Let us assume the measure of the one side of the section = x
Then
216 = 4s * 9
216 = 36s
s = 6
From the above deduction, it can be concluded that the measure of the one side of the section is 6 cm. I hope that the answer has actually come to your help.
