Is √10 in simplest form?

In a multiple regression analysis what would likely be the culprit of a dramatic increase in the P-value of one of the variables

makvit [3.9K]

This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity.
If there is a high correlation between your independent variables can lead to problems.
<span>It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.</span>

4(9x + 7) = x - 4<br><br> ALGEBRA 1!!

tiny-mole [99]

Hey!

-----------------------------------------------

Solution:

4(9x + 7) = x - 4

36x + 28 = x - 4

36x + 28 + 28 = x - 4 + 28

36x = x + (-32)

36x - x = x - (-24) - x

35x = -32

35x/35 = -32/35

x = -32/35

-----------------------------------------------

Answer:

x = -32/35

-----------------------------------------------

Determine whether there is a difference between the two data sets that is not apparent from a comparison of the measures of cent

Iteru [2.4K]

Answer:

It seems the question is incomplete as the two data sets implied from the question are not visible.

However, two data sets having identical measures of center have a difference.

Step-by-step explanation:

Let's consider these two data sets:

2, 2, 3, 5, 6, 6 and 1, 1, 1, 1, 1, 19

Both were contrived.

The most reliable among the measures of center is the mean. The mean of each is calculated by summing the data and dividing by the number of elements. In both sets, the mean is 4.

The data in the first set seem to be concentrated around the mean indeed. But for the second data set, one of them, 19, is obviously very far from the others and the mean. We need another measure to describe this: standard deviation.

Its formula is:

$\rho=\sqrt{\dfrac{\sum (x-\overline{x})^2}{n}}$

$x$ represents each data, $\overline{x}$ is the mean and $n$ is the number of items. $x-\overline{x}$ is the deviation from the mean of each data item.

For the first data set, $\rho=\sqrt{6}=2.45$

For the second data set,

$\rho=\sqrt{45}=6.71$

The low value of $\rho$ for the first set indicates that the items are all closer to the mean than for the second set.

Variance is the square of the standard deviation. It could also be used.

Which are true about the area of a circle? Check all that apply. The diameter is used in the formula. The units are always squar

jenyasd209 [6]

Answer:

selected the correct ones in bold

Step-by-step explanation:

The diameter is used in the formula. The units are always squared. The area can be found when given the diameter by first finding the radius. The area is the distance around the circle. Circumference can be used to find area.
