Step-by-step explanation:
Hope this helps!
x + (x+1) + (x+2) = 1200
combine like terms
3x+3=1200
subtract 3 from each side
3x =1197
divide by 3
c =399
Answer: 399, 400, 401
Answer: C. Substitute a value of x into the equation of a regression line and solve for y
Step-by-step explanation: To predict y values using equation of the regression line, a given value of x is substituted into the equation as there are only two unknowns in the whole regression equation, which are the x value ( independent variable) and the y value (the dependent or predicted variable).
The regression equation is usually of the form:
y = mx + c (linear regression)
Where y = predicted or dependent variable
m = slope or gradient of the regression line
x = independent variable
c = intercept of the line (where it cross the y-axis)
