A total of 655 persons have multiple job in a city. Of them, 381 are male, 299 are married and 168 are make and married. Find th
Nimfa-mama [501]

Probabilities are used to determine the chances of events

The probability that a randomly selected person with multiple jobs is a male or married is  0.782

<h3>How to determine the probability</h3>

The given parameters are:

Sample size, n = 655

Male = 381

Married = 299

Male and Married = 168

The number of those that are male or married is calculated as:

Male or Married = Male + Married - Male and Married

So, we have:

Male or Married = 381 + 299 - 168

Evaluate

Male or Married = 512

The probability is then calculated as:

p = 512/655

Evaluate

p = 0.782

Hence, the probability that a randomly selected person with multiple jobs is a male or married is  0.782

   −3x + 6 = 5  | -6   (first step is: "subtract 6 from both sides" <span>)
</span>
-3x = 5-6
-3x = -1      |  /(-3)   (second step is: "<span>divide by (-3) on both sides</span>" <span>)

Ksivusya [100]

Answer:

50 animals.

Step-by-step explanation:

We have been given that the population of a wildlife habitat is modeled by the equation p(t)=\frac{360}{1+6.2e^{-0.35t}}, where t is given in years. We are asked to find the the number of animals originally transported to the habitat.

To find the the number of animals originally transported to the habitat, we will substitute t=0 in our given equation as:

p(0)=\frac{360}{1+6.2e^{-0.35(0)}}

p(0)=\frac{360}{1+6.2e^{0}}

p(0)=\frac{360}{1+6.2(1)}

p(0)=\frac{360}{7.2}

p(0)=50

Therefore, 50 animals were originally transported to the habitat.
