The answer is 1/(x+4)
Explanation:
You would factor out the denominator
So,
(X-4)(x+4)=x^2-16
So, x-4/(x+4)(x-4)
Then x-4 cancels each other out from the numerator and denominator
Leaving 1/x+4

It is estimated that there are 828 motor vehicles in the US for every 1,000 people. If the number of motor vehicles in the US is
-BARSIC- [3]

Answer:

B) 314 million

Step-by-step explanation:

Given the following data;

Estimated motor vehicles = 828

Total number of motor vehicles = 260,000,000

Also, for 1,000 people, there are 828 motor vehicles.

Therefore, to find the population;

Population = \frac {260,000,000}{828}*1,000

Population = 314009.662 *1,000

Population = 314,009,662

Therefore, the population to the nearest millions is 314,000,000 people.

<u>Method II</u>

Motor vehicles = population

828 vehicles = 1000 people

260,000,000 vehicles = X people

Cross multiplying, we have;

828X = 260,000,000,000

X = \frac {260,000,000,000}{828}

X = 314,009,662

Therefore, the population to the nearest millions is 314,000,000 people.

pentagon [3]

Answer:

$6,200

Step-by-step explanation:

The question is to find the expected value.

We know the expected value of a scenario is the sum of the products of each probability of event and its profit or loss.

There are 3 probabilities in the scenario:

Rainy: 20% = 20/100 = 0.2

Sunny: 50% = 50/100 = 0.5

Cloudy: Rest, which is 100 - (50+20) = 100 - 70 = 30% = 30/100 = 0.3

Now, the gain and loss is:

Rainy: Lose 5000 means -5000

Cloudy: Gain 4000 means +4000

Sunny: Gain 12,000 means +12,000

Now, the expected value is:

Expected Value = (0.2)(-5000) + (0.5)(12000) + (0.3)(4000) =  $6,200
