What is x+61=45+85-180
Alekssandra [29.7K]

Answer: x = - 111

Step-by-step explanation:

  1. Add the like terms on the right side of the equation. 45 + 85 = 130. 130 - 180 = - 50. The equation simplifies to x + 61 = - 50
  2. Subtract 61 on both sides. x = - 111

Complete Question

The complete question is shown on the first uploaded image

Answer:

The coefficient  is  r  =0.81

Step-by-step explanation:

From the question we are told that

      cov(x, y )= 1260

      s_x^2 =  1600

     s_y^2  =  1225

Generally the coefficient of determination is mathematically represented as

      r  = [ \frac{cov(x,y)}{ \sqrt{s_x^2} *  \sqrt{s_y^2} }   ]^2

substituting values

      r  = [ \frac{ 1260}{ \sqrt{1600} *  \sqrt{1225} }   ]^2

     r  =0.81
