Answer:

12/13

Step-by-step explanation:

Since 4 of the 52 cards are queens, the number of cards that aren't queens is 52-4=48. This means that the probability of picking one of these cards is 48/52=12/13. Hope this helps!

Answer:

12/13

Step-by-step explanation:

There are 13 different faces of cards (1-10, jack, queen, and king). This means that there is a 1/13 probability of picking a queen. The question says "of NOT picking a queen" so you use the opposite of the probability of picking it: thus, 12/13

Answer:

x= -2, y = -3

Step-by-step explanation:

1. substitute x = 4+2y in the first equation: $\begin{bmatrix}2\left(4+2y\right)+y=-7\end{bmatrix}$

simplify it : $\begin{bmatrix}8+5y=-7\end{bmatrix}$

2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->

3. solve for y: 5y = -15 --> y = -15/5 --> y= -3

4. solve for x: x = 4 + 2y

x = 4 + 2(-3)

x = 4 + (-6)

x = -2

The length of a rectangle is 5 metres less than twice the breadth. If the perimeter is 50 meters,find the length and breadth

MAXImum [283]

As per the given question, it is stated that the length of a rectangle is 5 m less than twice the breadth.

Assumption : Let us assume the length as "l" and width as "b". So,

$\twoheadrightarrow \quad\sf{ Length =2(Width)-5}$

$\twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m}$

Also, we are given that the perimeter of the rectangle is 50 m. Basically, we need to apply here the formula of perimeter of rectangle which will act as a linear equation here.

$\\ \twoheadrightarrow \quad\sf{ Perimeter_{(Rectangle)} = 2(\ell +b) } \\$
