Step-by-step explanation:

all elements of the data set have the same value. therefore there is no difference of the individual values to the mean value.

and the sum of these differences is therefore also 0.

2(x - 2.6) + 2.91 = 7.71

Gennadij [26K]

I'll show a step-by-step. I'm not in the mood to explain right now lol.

2(x-2.6)+2.91=7.71

2x-5.2+2.91=7.71

+5.20 +5.20

2x+2.91=12.91

-2.91 -2.91

Need help with this<br>

AleksandrR [38]

Step-by-step explanation:

$\cos( \beta ) + \sin( \beta ) \tan( \beta ) = \sec( \beta )$

$\cos( \beta ) + \sin( \beta ) \frac{ \sin( \beta ) }{ \cos( \beta ) }$

$\cos( \beta ) + \frac{ \sin {}^{2} ( \beta ) }{ \cos( \beta ) }$

$\frac{ \cos {}^{2} ( \beta ) }{cos \beta } + \frac{ \sin {}^{2} ( \beta ) }{ \cos( \beta ) }$

$\frac{1}{ \cos( \beta ) }$

$= \sec( \beta )$

Put the following equation in slope-intercept form: 4y=4x+8

Sloan [31]

Answer:

y = x +2

Step-by-step explanation:

4y=4x+8

Slope intercept form is

y = mx+b so we need to solve for y

Divide each side by 4

4y/4 = 4x/4 +8/4

y = x +2

The slope is 1 and the y intercept is 2
