Answer:

D. \frac{2}{5}

Step-by-step explanation:

Since we know that the odds of an events can be found by dividing the probability that an event will occur by the probability that the event will not occur.

\text{Odds of an event}=\frac{\text{Probability that event will occur}}{\text{Probability that event will not occur}}

Probability of an event not occurring can be found by subtracting probability of the event occurring from 1.

\text{Odds of an event}=\frac{\text{Probability that event will occur}}{1-\text{Probability that event will occur} }  

We have been given that probability of an event is 2/7.  

Upon substituting our given values in above formula we will get,

\text{Odds of the given event}=\frac{\frac{2}{7}}{1-\frac{2}{7}} }

\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{7-2}{7}} }

\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{5}{7}} }

\text{Odds of the given event}=\frac{2}{7}\times \frac{7}{5}

\text{Odds of the given event}=\frac{2}{5}

Therefore, the odds of the same event are \frac{2}{5} and option D is the correct choice.

Which of the following equations is equivalent to x - y = 5?
Masja [62]

Answer:

6x-6y=30

Step-by-step explanation:

<u><em>The complete options are</em></u>

a) x - 2y = 30

b) 4x - 3y = 30

c) 3x - 4y = 30

d) 6x - 6y = 30

The given equation is

x-y=5

<u>Verify option d</u>

we have

6x-6y=30

Divide by 6 both sides

(6x-6y)/6=30/6

\frac{6x}{6}-\frac{6y}{6}=\frac{30}{6}

x-y=5

therefore

x-y=5  and 6x-6y=30 are equivalent

Graph the system of inequalities y&gt; 2x-3 and 3y-x≤6
Veronika [31]
Y > 2x - 3
3y - x ≤ 6
       ↓
y = 2x - 3
3y - x = 6

    3(2x - 3) - x = 6
3(2x) - 3(3) - x = 6
        6x - 9 - x = 6
        6x - x - 9 = 6
             5x - 9 = 6
             <u>    + 9 + 9</u>
                  <u>5x</u> = <u>15</u>
                   5      5
                    x = 3
y = 2x - 3
y = 2(3) - 3
y = 6 - 3
y = 3
(x, y) = (3, 3)

A rectangular prism of volume 3200 mm has a rectangular base of 10 mm and width 8 mm. Find the height h of the prism
Orlov [11]

Answer:

40 mm

Step-by-step explanation:

The rectangular prism of a rectangular box. The volume is given by the formula:

<u>Volume of Rectangular Prism</u> = length * width * height

Given Volume = 3200

Length = 10

Width = 8

We need to find height. So we plug in the given information and find the height, in mm. Shown below:

Volume = Length * Width * Height

3200 = 10 * 8 * Height

3200 = 80 * Height

Height = 3200/80

Height = 40 mm

The height (h) = 40 mm
