$\dfrac{3}{9}=\dfrac{3:3}{9:3}=\dfrac{1}{3}=0.3333...=0.\overline{3}\to B.$

for the future:

$\dfrac{1}{9}=0.\overline{1}\\\\\dfrac{2}{9}=0.\overline{2}\\\\\dfrac{3}{9}=0.\overline{3}\\\vdots\\\\\dfrac{n}{9}=0.\overline{n}\ for\ n\in\{1;\ 2;\ 3;\ ...;\ 9\}$

a game consists of randomly choosing a bag (labelled 1, 2 or 3) out of a choice of 100, and then again randomly, picking a ball

Anton [14]

Answer:

hello your question has some missing information attached below is the missing information

answer : 112 black balls

Step-by-step explanation:

Given data:

Each bag contains ; 10 balls

Total number of ball = 100 balls

<u>first: calculate the number of Black balls to be picked from the three bags</u>

From bag 1 = 0.4 * 0.35 * 10 = 1.4 balls

From bag 2 = 0.8 * 0.45 * 10 = 3.6 balls

From bag 3 = 0.3 * 0.2 * 10 = 0.6 ball

Total black balls picked = 5.6

∴ percentage of black balls picked given that each bag contains 10

5.6 / 10 * Total balls available = 56 balls = 56% of 100 balls

Hence If the player plays this game 200 times the number of black balls he will pick = 56% * 200 = 112 balls

What is the directrix of the parabola defined by 1/4(y+3)=(x-2)^2

Charra [1.4K]

This is a parabola which opens upwards and the directrix will be of the form
y = k

the general form is

4p(y - k) = (x - h)^2 we have:-

1/4(y + 3) = (x - 2)^2

so the vertex is at (2, -3)

4p = 1/4 so p = 1/16

so the focus will be at (2 , -2 15/16)

and directrix is y = -3 1/16

Freddy drilled into a piece of wood and a joist to attach them. He drilled 4 inches and the wood was 1 1/3 inches thick.

Angelina_Jolie [31]

The depth of the joist that was drilled by Freddy is 5 1/3 inches.

From the information given, we are informed that Freddy drilled into a piece of wood and a joist to attach them and that be drilled 4 inches and the wood was 1 1/3 inches thick.

Therefore, to get the depth that was drilled, we'll need to add the fractions given together. This will be:

= 4 + 1 1/3

= 5 1/3 inches.

Therefore, the depth of the joist that was drilled by Freddy is 5 1/3 inches.
