Students is Mrs. Kale’s class gathered data on the heights and weights of a sample of students in their class. They found a linear model for the data y=1.24x+12.6y=1.24x+12.6, where xx is the height in inches and yy is the weight in pounds. The actual value of a student 51 inches tall is 75 pounds. What is the approximate value of the residual for a student 51 inches tall

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
