-4 line under > SO -4 > x + 2 < 1

                              (-4 > x + 2) and (x + 2 < 1)


                               (x < -6)  and (x < 1)
     
                                Now combine the ranges

                                x line under < SO 

                                x < -6 is your answer

Brainliest if satisfied!!!

I hope this helped! 

I just did this so It was easy for me to get the answer!

that guy below is totally wrong 

its supposed to be a greater than or equal to sign.

negatives ALWAYS ARE ON THE LESS THEN

I hope this helped!

Suppose in this semester, our Exam 1 average was about 86 with an SD of about 10. Suppose the correlation between our Exam 1 and
Oduvanchick [21]

Answer:

the slope of the regression equation for predicting our Exam 2 scores from Exam 1 scores is 0.492

And the y-intercept of the regression equation for predicting our Exam 2 scores from Exam 1 is 33.688

Step-by-step explanation:

Given the data in the question;  

mean X" = 86

SD σx = 10

Y" = 76

SD σy = 8.2

r = 0.6

Here, Exam 2 is dependent and Exam 1 is independent.

The Regression equation is

y - Y" = r × σy/σx  ( x - x" )

we substitute

y - 76 = 0.6 × 8.2/10  ( x - 86 )

y  - 76 = 0.492( x - 86 )

y  - 76 = 0.492x - 42.312

y = 0.492x - 42.312 + 76

y = 0.492x + 33.688

Hence, the slope of the regression equation for predicting our Exam 2 scores from Exam 1 scores is 0.492

And the y-intercept of the regression equation for predicting our Exam 2 scores from Exam 1 is 33.688

What steps would you follow in order to solve the equation?
Ira Lisetskai [31]

Answer:

<h2>128</h2>

Step-by-step explanation:

Step one:

given the expression w/8 - 4 = 20

the first operation is to isolate the term that has w by adding 4 to both sides

w/8 - 4+4 = 20+4

w/8 = 16

Required

the value of w

Step two:

the next step is to cross multiply

w=16*8

w=128
