Use the scatterplot and line of best fit shown to
complete the statements.
When x = 5,
the observed value is blank
the predicted value is blank
the residual is blank

For this case we have that the trend line goes through the following points:

"A line of best fit passes through the y-axis at 1 and through the point 4 and 3"

That is, it goes through:

(0, 1)

(4, 3)

The equation of the line is:

y = mx + b
  

Where,

b = 1
  

The slope is:

m = (y2-y1) / (x2-x1)
 
 m = (3-1) / (4-0)

 m = (2) / (4)

 m = 1/2

Substituting values:

y = (1/2) x + 1


The equation of this line of best fit in slope-intercept form is:

y = one halfx + 1

Step-by-step explanation:

the observed value is 9

the predicted value is 7

the residual is 2

Step-by-step explanation:

the answer is $42.96

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
