Please help me w this an explain how you got it!.
pishuonlain [190]

Answer:

Vertex → (2, 4)

Step-by-step explanation:

Quadratic equation has been given as,

y = -x² + 4x

We rewrite this equation in the form of a function as,

f(x) = - x² + 4x

By comparing this equation with the standard quadratic equation,

y = ax² + bx + c

a = -1 and b = 4

Vertex of the parabola represented by this equation is given by [-\frac{b}{2a}, f(\frac{-b}{2a})]

x coordinate = -\frac{4}{2(-1)}

                     = 2

y-coordinate = f(2)

                     = - (2)² + 4(2)

                     = -4 + 8

                     = 4

Therefore, vertex of the given function is (2, 4)

The correlation between height and weight for a certain breed of plant is found to be 0.75. What percentage of the variability i
WINSTONCH [101]

Answer:

The percentage of the variability in plant weight is NOT explained by height is  

      p = 43.75%

Step-by-step explanation:

From the question we are told that

      The correlation between height and weight is  r = 0.75

Generally the R-Squared  between height and weight is mathematically represented as

        R - square  =  r^2

substituting values

         R - square  =  0.75^2

         R - square  =  0.563

This R-Squared tells us the percentage of plant weight is accounted by height

and from the calculation we see that it is  56.3%

Now the percentage of plant weight that is not accounted by height is

          p =  100 - 56.3

          p = 43.75%
