How many houses have an area less than 100 m² ?
dsp73

Answer:

This question overall depends on a continuously changing factor.

Step-by-step explanation:

There are many houses in this world that have an area of less than 100 m^2, while many others have up to 700, 800, or even 1000 m^2 of land. Your question is impossible to calculate because of the massive amount of houses in this world. If you want a good estimate, say around 0.9 to 1.8 billion.

What are the possible values of x in x2 + 3x + 3 = 0?
e-lub [12.9K]

To solve a quadratic equation like ax^2+bx+c=0, you can use the quadratic formula

x_{1,2} = \cfrac{-b\pm\sqrt{b^2-4ac}}{2a}

In your case, a = 1, b = c = 3, so the formula becomes

x_{1,2} = \cfrac{-3\pm\sqrt{(-3)^2-4\cdot 1\cdot 3}}{2\cdot 1}

We can simplify the expression:

x_{1,2} = \cfrac{-3\pm\sqrt{9-12}}{2} = \cfrac{-3\pm\sqrt{-3}}{2}

Since -3 is negative, its square root is computed as

\sqrt{-3} = \sqrt{-1\cdot 3} = \sqrt{-1}\sqrt{3} = \sqrt{3}i

So, the solutions are

x = \cfrac{-3+i\sqrt{3}}{2} \text{ or } x = \cfrac{-3-i\sqrt{3}}{2}

There are 6 brown, 5 blue, and 2 orange marbles in a hat. What is the probability of picking two orange marbles in a row without
xenn [34]
<span>The correct answer is 1/78.

Explanation<span>:
There are 2 orange marbles out of 13 total marbles, so the probability of your first marble being orange is 2/13.

After this one is drawn, since it is not returned, the probability of getting a second orange marble is 1/12, since there is only 1 orange marble left out of 12 total marbles.

This gives us the total probability 2/13(1/12)=2/156=1/78.</span></span>
