Rebekah6356 the equation of the trend line on the scatterplot below is y=1.38x-0.52. using the trend line equation, what is the predicted approximate value of y when x = 3.5? 2.98 4.02 4.31 5.35 mathdragon 4.31

4.31

Step-by-step explanation:

Just plug in 3.5 for x in your equation and do the math.  y = 1.38(3.5) - .52,

y = 4.83 - .52

y = 4.31

use formula for the circle a=3.14

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
