Answer:

1/6

Step-by-step explanation:

Firstly, Pr(e) = n(e)/Total outcome

Pr(2) = 1/3

Pr(1) = 1/2

Pr(1 and 2) = 1/3 * 1/2 = 1/6

Gwar [14]

Find

R(V)

  • p(x)×x
  • x(-3/2x+112)
  • -3/2x²+112x

Now

  • y=-3/2x²+112x

Find vertex x coordinate

  • -b/2a
  • -112/-2(-3/2)
  • -37.3

Put in equation

  • y=-3/2(-37.3)²+112(-37.3)
  • y=-2086.9-84+4177.6
  • y=$6264.6
  • y=$62.64M

As a is negative parabola is facing downwards hence vertex is minimum .

So minimum value is $62M which is far more than given .

Endpoint given the Midpoint: * The midpoint of RP is M(2, 4). If one of the end points is R(-1,7), find the coordinates of the o
marin [14]

Answer:

The coordinates of other point are: (5,1)

Step-by-step explanation:

Given coordinates are:

M(x,y) = (2,4)

R(x_1,x_2) = (-1,7)

We have to find the coordinates of other point (x2,y2)

The formula for mid-point is given by:

M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Putting the values we get

(2,4) = (\frac{-1+x_2}{2}, \frac{7+y_2}{2})

Putting respective elements equal

\frac{-1+x_2}{2} = 2\\-1+x_2 = 2*2\\-1+x_2 = 4\\x_2 = 4+1\\x_2 = 5\\And\\\frac{7+y_2}{2} = 4\\7+y_2 = 4*2\\7+y_2 = 8\\y_2 = 8-7\\y_2 = 1

Hence,

The coordinates of other point are: (5,1)
