8 0

Answer:

No, the given polynomial is not prime.

Step-by-step explanation:

Given: a polynomial 12n^2+12n+1

To check: whether the given polynomial is prime or not.

Solution:

A prime polynomial is a polynomial that cannot be factored into polynomials of lower degree and has integers as coefficients.

In the given polynomial, coefficients are integers.

Also, the polynomial 12n^2+12n+1 cannot be factored further into polynomials of lower degree.

So, the given polynomial is not prime.

How is a line of best fit drawn? Describe how you decide where to put it.
Gnoma [55]

Answer:

A line of best fit is a straight line going through a trend on a scatter plot.

Step-by-step explanation:

A well drawn line of best fit is just a line going straight through the trend of dots to approximate an exact trend from a non-exact plot, so just draw a line that stays in the middle of the dots and you should do great.

Hope this helped!

So in the thing p=m/v to find m would you times v by p?
EastWind [94]

M = mass

p = density

v = volume

Yes, to find m it would be m = pv.

To find v that would be m/p.

Area of one tile = 0.3² m² = 0.09 m²

Multiply the number of tiles by 0.09 m².

Find the residual values, and use the graphing calculator tool to make a residual plot. A 4-column table with 5 rows. The first
Svetlanka [38]

The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern

X         Given     Predicted     Residual value

1            3.5           4.06             -0.56

2           2.3           2.09             0.21

3            1.1            0.12               0.98

4           2.2           -1.85              4.05

5          -4.1            -3.82            -0.28

The residual value is calculated as follows using this formula: ( Given - predicted )

1) ( 3.5 - 4.06 ) = -0.56

2) ( 2.3 - 2.09 ) = 0.21

3) ( 1.1 - 0.12 ) = 0.98

4) (2.2 - (-1.85) = 4.05

5) ( -4.1 - (-3.82) = -0.28

Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .

attached below is the residual plot of the data set

hence we can conclude from the residual plot attached below that the line of best fit is appropriate for the data because the points have no clear pattern ( i.e. scattered )
