Answer:

P(number greater than 3) = \frac{7}{12}

Step-by-step explanation:

The  Probability of  getting a number greater than 3  means the possibility of getting 4  or 5 or 6

That is

P(number greater than 3) =  P(getting 4)  +  P(getting 5) + P(getting 6)

On substituting the values from the table ,

we get

P(number greater than 3)  = \frac{2}{12} +  \frac{2}{12} + \frac{3}{12}

P(number greater than 3) = \frac{7}{12}

Thus if the number cube is tossed once, P(number greater than 3) is  \frac{7}{12}

What is the vertex of the graph of the following equation? y = x^2 + 2x-3
ExtremeBDS [4]

Answer:

vertex = (- 1, - 4 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - \frac{b}{2a}

y = x² + 2x - 3 ← is in standard form

with a = 1, b = 2 , then

x = - \frac{2}{2} = - 1

Substitute x = - 1 into the equation for corresponding value of y

y = (- 1)² + 2(- 1) - 3 = 1 - 2 - 3 = - 4

vertex = (- 1, - 4 )
