Let's attribute a to equal probability of 2 and b to equal probability of 3
A=54/360 B=62/360
"or" means you combine the probabilities which means that AvB =116/360
now simply divide 116 by 360 and you get your answer which is 0.32
A is the correct answer my dude

Answer:

3. $\displaystyle y = \frac{2}{5}x + 1\frac{2}{5}$

2. $\displaystyle y = -\frac{5}{7}x + 2$

1. $\displaystyle y = -2x + 4$

Step-by-step explanation:

3. 2x - 5y = −7

- 2x - 2x

__________

$\displaystyle \frac{-5y}{-5} = \frac{-2x - 7}{-5} \\ \\ y = \frac{2}{5}x + 1\frac{2}{5}$

2. 5x + 7y = 14

- 5x - 5x

__________

$\displaystyle \frac{7y}{7} = \frac{-5x + 14}{7} \\ \\ y = -\frac{5}{7}x + 2$

1. 6x + 3y = 12

- 6x - 6x

__________

$\displaystyle \frac{3y}{3} = \frac{-6x + 12}{3} \\ \\ y = -2x + 4$

The area of a rectangle is 42 ft squared, and the length of the rectangle is 5 ft more than twice the width. Find the dimensions

stira [4]

Answer:

<h3>Length = 12 ft</h3>

Width = $\frac{7}{2} ft$

Step-by-step explanation:

Given,

Area of rectangle = $42 \: {ft}^{2}$

Width = X

Length = 2x + 5

Now,

$x(2x + 5) = 42$

$2 {x}^{2} + 5x = 42$

$2 {x}^{2} + 5x - 42 = 0$

$2 {x}^{2} + 12x - 7x - 42 = 0$

$2x(x + 6) - 7(x + 6) = 0$

$(2x - 7)(x + 6) = 0$

Either

$2x - 7 = 0$

$2x = 0 + 7$

$2x = 7$

$x = \frac{7}{2}$

Or,

$x + 6 = 0$

$x = 0 - 6$

$x = - 6$

Negative value can't be taken.

So, width = $\frac{7}{2} ft$

Again,

Finding the value of length,

Length = $2x + 5$

$2 \times \frac{7}{2} + 5$

$7 + 5$

$12$

Length = 12 ft
