This event can be broken down into two sub-event. 
1) The person selected is male
AND
2) The person feels that crime is the biggest problem
The probability of 1:
(118 + 239 + 458)/1999
= 0.4077
The probability of 2:
118/815
= 0.1448
Probability of both occurring:
0.4077 * 0.1448
= 0.0590
= 5.9%
The answer is A

The Fibonacci sequence was first discovered during a study of rabbits. If newborn rabbits become adults in one month, each pair
Rina8888 [55]

Answer:

There will be 233 pairs of rabbits would be produced after thirteen months.

Step-by-step explanation:

Consider the provided information.

In the Fibonacci sequence we can find the next term by adding the two numbers before it.

Let us consider that we have 1 pair of newborn rabbits in first month.

Then in the second month they will fully grow.

On the next month 1 more pair of baby rabbits were born.

Next month the baby rabbits were grown and the first pair had two more baby rabbits.

Thus the sequence will look like:

Sequence: 1, 1, 2, 3

It is given that the it follows the Fibonacci sequence. Now use the above rule to generate the Fibonacci sequence.

The required Sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233...

We need to find the number of pairs of rabbits would be produced after thirteen months.

Now from the above sequence we can find the number of rabbits produced after thirteen months.

Hence, there will be 233 pairs of rabbits would be produced after thirteen months.

It takes 12 minutes to fill an entire bathtub using both the cold and hot water. If just the cold water is used, it takes 18 min
Kipish [7]

Answer:

<h2>It takes 36 minutes to fill the bathtub using just hot water.</h2>

Step-by-step explanation:

We are gonna name V the complete volume of the bathtub, which is filled a certain amount of minutes. Each filling rate or speed is gonna be expressed as: \frac{V}{t}.

So, if we apply this consideration to each case we have:

Using cold and hot water: \frac{V}{12}

Using only cold water: \frac{V}{18}

Using only hot water: \frac{V}{x}; because we don't knot the time it takes to fill the bathtub with hot water.

Now, as you can see, Cold and Hot water is a sum of cold water only and hot water only:

\frac{V}{12}=\frac{V}{18}+\frac{V}{x}

Solving the equation for <em>x: </em>

\frac{V}{12}=\frac{xV+18V}{18x} \\\frac{V}{12}=\frac{(x+18)V}{18x}\\\\\frac{18xV}{V}=12(x+18)\\18x=12x+216\\18x-12x=216\\6x=216\\x=\frac{216}{6}=36

Therefore, it takes 36 minutes to fill the bathtub using just hot water.

1. The first step is to realize you need to find a number that will be bigger than 74. 
2. All you have to do for this problem is to divide 74 by 90%. You can put this in the calculator by typing in (74 / .9).
3. The answer you get should be 82.22
4. You can check this by multiplying 82.22 by 90%, and it should bring you back to 74.
