3. One ball is selected at random from a bag containing 12 balls of which x are white.
(a) What is the probability of selecting a white ball?
When a further 6 white balls are added the probability of selecting a
white ball is doubled.
(b) Find x.​

c

step-by-step explanation:

i think because what else can be a sample of every member

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

the football players are volunteering for the test.

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
