Hi, can you please help me answer this direct proportion question?
Oksanka [162]

Answer:

X = 100

Step-by-step explanation:

  • In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
  • This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.
  1. Multiply the left by k, so y = \frac{k}{\sqrt{x} }
  2. we know that y= 5, for x = 36, so sub this in the equation
  3. 5 = \frac{k}{\sqrt{36} }
  4. simplify5 = \frac{k}{6 }
  5. re-arrange for k, <u>k = 5*6 = 30</u>
  6. now we know k, we can create the real equation, y = \frac{30}{\sqrt{x} }
  7. sub in 3 as y
  8. 3 = \frac{30}{\sqrt{x} }
  9. <u>x = 100</u>

Zinaida [17]

Answer:

The probability of of a randomly chosen student being exactly 21 years old.

= 1.293

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given Population  size n = 500</em>

<em>Mean of the Population = 20 years and 6 months</em>

<em>                                        = </em>20 + \frac{6}{12} = 20 +0.5 = 20.5 years<em></em>

<em>Standard deviation of the Population = 2 years</em>

Let 'X' be the range of ages of the students on campus follows a normal distribution

Let   x =21

            Z = \frac{x-mean}{S.D}

            Z = \frac{x-mean}{S.D} = \frac{21-20.6}{2} =0.2

<em>The probability of a randomly chosen student being exactly 21 years old.</em>

<em>P( Z≤21) =  0.5 + A( 0.2) </em>

            = 0.5 +0.793

           =  1.293
