It all depends on how many girls or boys are in the class because if there are 19 boys in the class and there are 30 in the class altogether then the probability would be 11/30 or 36.666%

An expression is shown below: 3pf2 − 21p2f + 6pf − 42p2 Part A: Rewrite the expression by factoring out the greatest common fact
Contact [7]

Answer:

3pf² - 21p²f + 6pf - 42p²

= 3pf² + 6pf - 21p²f - 42p²

= 3pf(f +2) - 21p²(f + 2)

= (3pf - 21p²)(f +0 2)

Answer: (3pf - 21p²)(f + 2)

I lost in this problem and I can’t find my way out
elixir [45]
Two angle that form a linear pair are supplementary meaning they add to equal 180° (straight line).

make the bigger angle = x
then smaller angle = x - 30°

x + x - 30 = 180
2x - 30 = 180
2x = 180 + 30
2x = 210
x = 210/2
x = 105

The question is to find the smaller angle which was: x - 30

105 - 30 = 75°

Which statement is true concerning the vertex and axis of symmetry of h(x)=−2x2+8x?
frozen [14]

Answer:

the vertex is at (2, 8) and the axis of symmetry is x = 2

Step-by-step explanation:

In h(x)=−2x2+8x please use the symbol " ^ " to indicate exponentiation:

h(x)=−2x^2+8x      

This is a quadratic equation with coefficients a = -2, b = 8 and c = 0.

The axis of symmetry equation is x = -b/ (2a).

                                                                                                -8

Here, with a = -2 and b = 8, the axis of symmetry is   x = --------- = 2

                                                                                               2(-2)

To find the y-coordinate of the vertex, substitute 2 for x in h(x)=−2x^2+8x, obtaining

h(2) = -2(2)^2 + 8(2) = -2(4) + 16 = 8

In summary, the vertex is at (2, 8) and the axis of symmetry is x = 2.
