Step-by-step explanation:

In research we have two types of variables: the quantitative and the qualitative variables.

In this example we are asked about our favorite city, we can see that the possible answers for this question are: Dallas, Seattle, Washington, Paris, etc.. these are not numbers so therefore this is an example of qualitative variable.

Answer:

  $10,625.99

Step-by-step explanation:

The future value formula is useful for this.

  FV = P(1 +r/n)^(nt)

where interest at rate r is compounded n times per year for t years. P represents the principal invested.

  FV = $10,000(1 +.03/4)^(4·2) = $10000(1.0075^8) ≈ $10,625.99

The accumulated value will be $10,625.99.

Answer:

Step-by-step explanation:

f(x) = 2x + 4

g(x) = 4x² + 1

In order to find (g ∘ f)(0) we must first find

(g ° f )(x)

To find (g ° f )(x) substitute f(x) into g(x) that's for every x in g(x) replace it with f(x)

That's

We have

Now to find (g ∘ f)(0) substitute the value of x that's 0 into (g ∘ f)(0)

Making the value of 'a' smaller, but still positive, will make the graph be compressed vertically.

Let's say a = 1 is the initial value. If we update it to a = 0.5, then the graph will be half as tall as it used to be, so it's compressed by a factor of 1/0.5 = 2.

The value of b determines the period of the sinusoidal function.

Answer:

Option C : P = $1040

Step-by-step explanation:

Using formula for continuous compounding, we have;

FV = Pe^(rt)

Where;

FV is the future value

P is the starting principal

r is the interest rate

t is time period

Now, from the question;

After 9 years, value is 1,866.79

Hence;

Pe^(9r) = 1,866.79 - - - eq1

Also, after 18 years;

Pe^(18r) = $3,350.87

Now, from exponential functions,

e^(4) can be written as (e^(2))²

Thus,in our case, e^(18r) can simply be written as (e^(9r))²

Thus, we can write Pe^(18r) = $3,350.87 as;

P(e^(9r))² = 3,350.87 - - - eq3

Thus, dividing eq 1 by eq 3 gives;

P(e^(9r))²/Pe^(9r) = 3350.87/1866.79

e^(9r) = 1.794990331

So;

In 1.794990331 = 9r

r = 0.585/9

r = 0.065

Putting this for r in equation 1 gives;

Pe^(9 × 0.065) = 1,866.79

1.795P = 1,866.79

P = 1866.79/1.795

P = $1040

Answer:

slope = -5/2

the y-intercept is the point (0, 3)

Step-by-step explanation:

Notice the equation is given to you already in slope-intercept form, o you can extract those values directly:

Slope is the factor accompanying the variable x , that is the fraction -5/2 and the y value of the y-intercept is the "+3" that follows.

So the slope = -5/2

and the y-intercept is the point (0, 3) because x must be always  zero when the line intersects the y-axis.

Answer:

1/3 of the gas.

Step-by-step explanation:

1 - 1/2 = 1/2

1/3 - 3/3 = 2/3

2/3 ( 1/2 ) = 1/3

The amount of gas left with Jess is given by the equation A = 1/6 of the total gas

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount of the gas be represented as A

Now , the equation will be

The amount of gas utilized by Jess on Friday = 1/2 of the initial gas

So , The amount of gas left on Friday = A - ( 1/2 ) A

On simplifying the equation , we get

The amount of gas left on Friday = ( 1/2 )A

Now ,

Amount of gas utilized by Jess on Saturday = ( 1/3 ) of the remaining gas

On simplifying the equation , we get

The remaining gas = ( 1/2 ) A - ( 1/3 ) A

So , the remaining amount of gas with Jess = ( 1/6 ) of the total gas

Hence , the equation is ( 1/6 ) of the total gas is remaining

From the question we are told that

   The proportion that own a cell phone  is  [tex]p = 0.90[/tex]

    The  sample  size is  n =  15

Generally the appropriate distribution for X is mathematically  represented as

      [tex]X \ is \ B( n , p )[/tex]

So  

       [tex]X \ is \ B( 15 , 0.90 )[/tex]

Generally the number students that  own a cell phone in a simple random sample of 15 students is mathematically represented as

              [tex]\mu = n * p[/tex]

              [tex]\mu = 15 * 0.90[/tex]

              [tex]\mu = 13.5[/tex]

Generally the standard deviation of the number of students who own a cell phone in a simple random sample of 15 students is mathematically represented as

                [tex]\sigma = \sqrt{ n * p * q }[/tex]

Where  q is mathematically evaluated as

          [tex]q = 1- p[/tex]

           [tex]q = 1- 0.90[/tex]

           [tex]q = 0.10[/tex]

            [tex]\sigma = \sqrt{ 15 * 0.90 * 0.10 }[/tex]

            [tex]\sigma = 1.16[/tex]

Generally the probability that all students in a simple random sample of 15 students own a cell phone is mathematically represented as

   [tex]P(X = 15) = \left 15} \atop {}} \right.C_{15} * p^{15} * q^{15 - 15}[/tex]    

     [tex]P(X = 15) = \left 15} \atop {}} \right.C_{15} * (0.90)^{15} * (0.10 )^{15 - 15}[/tex]

From the combination calculator  is      [tex]\left 15} \atop {}} \right.C_{15} = 1[/tex]

     [tex]P(X = 15) = 1 * 0.205891 * 1[/tex]

      [tex]P(X = 15) = 0.206[/tex]

The appropriate distribution for X is M(15, 0.9).

On average 1.345 students will own a cell phone in a simple random sample of 15 students.

The standard deviation of the number of students who own a cell phone in a simple random sample of 15 students is 1.16.

The probability that all students in a simple random sample of 15 students own a cell phone is 0.206.

It is estimated that approximately 90% of students now own a cell phone. Fifteen students are to be selected at random from a large university.

Assume that the proportion of students who own a cell phone at this university is the same as nationwide.

According to the question,

Let X = the number of students in the sample of 15 who own a cell phone.

1. The appropriate distribution for X is,

the sample size is n equals 15 and the proportion of the cell phone is 90% = 0.9.

The appropriate distribution for X is M(15, 0.9).

2. On average students will own a cell phone in a simple random sample of 15 students is,

[tex]\mu = n \times p\\\\\mu = 15 \times 0.9\\\\\mu = 1.345[/tex]

Answer:

w = p/2 - l

Step-by-step explanation:

When a question asks to be solved by a variable it means to get that variable on one side.

Now all we have to do is subtract l on both sides. Now we know that

w = p/2 - l

Answer:

The travel time to work that separates the 8% of people with the shortest travel times from the other 92% with longer travel times is 10.6 minutes.

Step-by-step explanation:

We are given that the average travel time to work for a person living and working in Kokomo, Indiana is 17 minutes.

Suppose the standard deviation of travel time to work is 4.5 minutes and the distribution of travel time is approximately normally distributed.

Let X = the distribution of travel time

The z-score probability distribution for the normal distribution is given by;

                               Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = average travel time = 17 minutes

            [tex]\sigma[/tex] = standard deviation = 4.5 minutes

So, X ~ Normal([tex]\mu=17, \sigma^{2} =4.5^{2}[/tex])

Now, we have to find the travel time to work that separates the 8% of people with the shortest travel times from the other 92% with longer travel times, that means;

            P(X < x) = 0.08      {where x is the required travel time}

            P( [tex]\frac{X-\mu}{\sigma}[/tex] < [tex]\frac{x-17}{4.5}[/tex] ) = 0.08

            P(Z < [tex]\frac{x-17}{4.5}[/tex] ) = 0.08

In the z table the critical value of z that represents the below 8% of the area is given by -1.43, that is;

                         [tex]\frac{x-17}{4.5}=-1.43[/tex]

                         [tex]{x-17}{}=-1.43\times 4.5[/tex]

                         x = 17 - 6.435 = 10.6 minutes

Hence, the travel time to work that separates the 8% of people with the shortest travel times from the other 92% with longer travel times is 10.6 minutes.
