A scientist is studying the relationship of two quantities S and T in an experiment. The scientist finds that
under certain conditions, as the quantity of S increases, the quantity of T decreases. After taking
measurements, the scientist determines that the rate of change of the quantity of S with respect to the
quantity of T present is inversely proportional to the natural logarithm of the quantity of T. Which of the
following is a differential equation that could describe this relationship?

Answers

Answer 1

Differential equation is a way to represents the function and its variable by relating them.Hence the differential equation that describe the relationship between S and T is,

[tex]S \propto \dfrac{1}{log_e T}[/tex]

Given-

The quantity of S increases, the quantity of T decreases.

The rate of change of the quantity of S with respect to the  quantity of T present is inversely proportional to the natural logarithm of the quantity of T.

What is differential equation?

Differential equation is a way to represents the function and its variable by relating them.

As the quantity of S changes with respect to the  quantity of T present is inversely proportional. Thus,

[tex]S \propto \dfrac{1}{T}[/tex]

But quantity of S changes inversely proportional to the natural logarithm of the quantity of T. The natural logarithm of a  number is its logarithm to the base of e (constant).

Thus the equation can be given is,

[tex]S \propto \dfrac{1}{log_e T}[/tex]

Hence the differential equation that describe the relationship between S and T is,

[tex]S \propto \dfrac{1}{log_e T}[/tex]

Mel paid $15.75 for 6 greeting
cards. Some of the cards cost
$2.50 each, and some cost $3.25
each. Let x represent the number
of cards that cost $2.50 each,
and y represent the number of
cards that cost $3.25 each. This
situation can be represented by
the system x + y = 6 and
2.5x + 3.25y = 15.75. How many
of each type of card did Mei
purchase?

Answers

Answer:

Step-by-step explanation:

x + y = 6 -------------(I)

    y = 6 -x

2.5x + 3.25y = 15.75 -------------(II)

substitute y = 6 - x in equation (II)

2.5x + 3.25*(6 - x) = 15.75      {Distributive property: a(b +c) =a*b + b*c}

2.5x + 3.25*6 - x * 3.25 = 15.75    

2.5x + 19.5 - 3.25x = 15.75

2.5x - 3.25x + 19.5 = 15.75    {Combine like terms}

-0.75x +  19.5 = 15.75

            -0.75x=15.75 - 19.5

           -0.75x = -3.75

                  x = -3.75/-0.75

                  x = 5

Plugin x = 5 in (I)

5 + y = 6

     y = 6 - 5

    y = 1

A group of campers walked 4 2/3 miles along a hiking trail. Another group of campers walked 1/4 of that distance with the first group before turning off onto another trail. How many miles did the two groups of campers walk with one another ?

Answers

Answer:

14 / 12 miles or 1 1/6 miles

Step-by-step explanation:

A group of campers walked 4 2/3 miles along a hiking trail.

Distance = 4 2/3 miles

Another group of campers walked 1/4 of that distance with the first group before turning off onto another trail.

That is; 1/4 of 4 2/3 miles

How many miles did the two groups of campers walk with one another ?

This is obtained by solving 1/4 of 4 2/3 miles

Converting 4 2/3 to an improper fraction;

4 2/3 = 14 / 3 Miles

1/4 of 14 / 3

1 / 4 * 14 / 3

= 14 / 12 miles or 1 1/6 miles

(a) X is a random variable such that MX(t) = e 6t 2 when |t| < 2. (b) Y is a random variable such that MY (t) = 2 2−t for t < 0.5. (c) Z is a random variable such that MZ(t) = [infinity] for t ≥ 5. (d) W is a random variable such that MW (2)

Answers

Answer:

a.) X  ≈ N (0, 12)

b.) Y ≈  exp(2)

c.) The given distribution is not defined.

d.) Not a standard form of any distribution .

Step-by-step explanation:

Given - In parts (a)−(d) below, either use the information given to determine

            the distribution of the random variable, or show that the information

            given is not sufficient by describing at least two different random

            variables that satisfy the given condition.

To find - (a) X is a random variable such that Mₓ(t) = [tex]e^{6t^{2} }[/tex] when |t| < 2.

              (b) Y is a random variable such that  [tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.

              (c) Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.

              (d) W is a random variable such that [tex]M_{W}[/tex](2) = 2

Proof -

a.)

As we know that the moment generating function of normal distribution is given by

Mₓ(t) = [tex]e^{ut + \frac{1}{2}t^{2} \sigma^{2}}[/tex]

Now,

Mₓ(t) = [tex]e^{6t^{2} }[/tex]

       = [tex]e^{0(t) + \frac{12}{2} t^{2} }[/tex]

⇒μ = 0, σ = 12

Nd it is represented by

X  ≈ N (0, 12)

b.)

Moment generating function of exponential function is given by

[tex]M_{Y}[/tex](t) = [tex]( 1 - \frac{t}{\theta})^{-1}[/tex]

Now,

 [tex]M_{Y}[/tex](t) = [tex]\frac{2}{2 - t}[/tex] for t < 0.5.

          = [tex]\frac{1}{\frac{2 - t}{2} }[/tex]

          = [tex]\frac{1}{1 - \frac{t}{2} }[/tex]

          = [tex]( 1 - \frac{t}{2} )^{-1}[/tex]

And it is represented by

Y ≈  exp(2)

c.)

Z is a random variable such that [tex]M_{Z}[/tex](t) = ∞ for t ≥ 5.

The given distribution is undefined.

d.)

[tex]M_{W}[/tex](2) = E([tex]e^{2w}[/tex] )

           = [tex]\int\limits^{-\infty}_{\infty} {e^{2w} f(w) } \, dw[/tex]

          = 2

It is not the standard form of any distribution.

Alex borrowed $3500 from two banks. One bank charged a simple interest of 8% and another bank
charged a simple interest of 12%. If he paid a total interest of $332 for one year, find the amount that he
borrowed from each bank.

Answers

Answer:

$ 2,200 for 8%, $ 1,300 for 12%

Step-by-step explanation:

I=PRT

Let Bank 1 be x

332= x (8%) + (3,500-x) 12%

332= x (0.08) + (3,500-x) 0.12   change the percent to decimal

332= 0.08x + 420 - 0.12x

0.04x= 420-332

x= [tex]\frac{88}{0.04}[/tex]

x= 2,200 (Bank 1)

Bank 2= 3,500-Bank 1

Bank 2= 3,500- 2,200

Bank 2= 1,300

If 13 candy bars cost $19.76, how much do 20 candy bars cost?

Answers

Answer:

$30.40

Step-by-step explanation:

to find out how much 20 candy bars would cost, first, we have to find out how much 1 candy bar costs. we do this by dividing $19.76 by 13.

$19.76 ÷ 13 = $1.52

so now we know that one candy bar costs $1.52. now, we multiply this value to 20, to know how much 20 candy bars cost. therefore, we get:

20 × $1.52 = $30.40
