The answer would be B because there are 4 queens in a deck of cards. with there being 52 cards in a deck, you divide 4 by 52. If you put that into a fraction it’s 4/52. simplified, its 1/13. therefore, there’s a 1/13 chance on getting a queen

Answer:

B) 1/13

Step-by-step explanation:

This is because as we all know there are four different category of cards - spades, clover, heart and diamond.

In each of these category we have 1 Queen so in total we have 4 Queens

Probability of choosing Queen = 4/52

= 1/13

(This is your answer hope it helps :))

Use:

(a-b)^2=a^2-2ab+b^2\qquad(*)

x^2+y^2-6y-12=0\ \ \ \ |+12\\\\x^2+y^2-6y=12\\\\x^2+y^2-2y\cdot3=12\ \ \ \ |+3^2\\\\x^2+\underbrace{y^2-2\cdot y\cdot3+3^2}_{(*)}=12+3^2\\\\x^2+(y-3)^2=21\\\\\boxed{k=3}

Find all solutions of the equation in the interval [0,2pi)
irinina [24]

Answer:

{π/4, 5π/4}

Step-by-step explanation:

Tan theta -1=0 could be rewritten as tan Ф = 1.  The tangent function is 1 at Ф = π/4.  As the period of the tangent function is π,

tan Ф = 1 will be true for Ф = π/4 + π, or (5/4)π.

The solution set is {π/4, 5π/4}.

Fraction of the shape shaded on these two shapes??
xxTIMURxx [149]
The one of the left isn't too tricky, in the bottom left of it you have 1/2 of 1/4 of the shape, and on the bottom right you have 1/4 of 1/4. Imagine the whole shape was cut up like that bottom right bit into 16 triangles, then you would have three of them shaded (see my diagram).

The one on the right seems like guesswork to me, so I'm sorry if I'm wrong. It look like you just have to use your eyes to work out how much of the bottom half of the shape is shaded: looks like 1/16 to me (i.e. you can draw four of those along and four down, again, see my diagram.) So plus the top half, which is 8/16, you get 9/16.

Answers: left picture: 3/16.
                 right picture: 9/16.
