Answers

Answer 1

Based on this information, we can estimate that a 1,000-person increase in population at the destination, an increase of 441 auto-mode social/recreational trips from the origin during the peak hour time

a 10-mile increase in distance to the destination, and the presence of recreational facilities at the destination are associated with an increase of 725 x (0.43 + (-0.07) + 0.62) = 441 auto-mode social/recreational trips from the origin during the peak hour.

1. Calculate the total increase in auto-mode social/recreational trips from the origin during the peak hour associated with a 1,000-person increase in population at the destination, a 10-mile increase in distance to the destination, and the presence of recreational facilities at the destination by multiplying the coefficients of the logit model by 725 (the total number of trips):

725 x (0.43 + (-0.07) + 0.62) = 441

2. Therefore, we can estimate that a 1,000-person increase in population at the destination, a 10-mile increase in distance to the destination, and the presence of recreational facilities at the destination are associated with an increase of 441 auto-mode social/recreational trips from the origin during the peak hour time.

mark dropped an object from a bridge 400400 feet above ground level with an initial velocity of 0.0. he knows that the gravitational pull of the earth is about 1616 feet per second squared. he wants to find how many seconds, t,t, it will take the object to hit the ground. match each expression with the correct equation that models this situation or solution

Answers

The correct equation is t = 5 seconds.

What is equation ?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :

y(t) = -16t² + 0t + 400

and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:

0 = -16t² + 0t + 400

16t² + 0t - 400 = 0

which solving for "t" becomes:

16t² - 400 = 0

16t² = 400

t² = 25

t = √25

t = ± 5

So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.

That is: t = 5 seconds

Answers

Answer:

(10 * 312) + (10 * 612) + (10 * 812)

Step-by-step explanation:

To find the total amount of shampoo that Christa purchased in ounces, we can use the expression (10 * 312) + (10 * 612) + (10 * 812), which is equivalent to the expression that Christa used. This expression is also equivalent to 3120 + 6120 + 8120, which can be simplified to 3120 + 6120 + 8120 = 3120 + 6150 + 8100 = 9280 + 6150 = 15,430. Therefore, the expression (10 * 312) + (10 * 612) + (10 * 812) is equivalent to 15,430.

12. More than one shark attack next year: 0.001.

13. At least one shark attack in the next 100 years: 0.982.

What is the Poisson distribution?

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following equation:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are:

x is the number of successes that we want to find the probability of.e = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval or range of values of the input parameter.

Considering that there have been 8 attacks in 200 years, the mean for n years is given as follows:

[tex]\mu = \frac{8n}{200}[/tex]

Hence the probability of one shark attack in the next year(n = 1, mean = 0.04) is given as follows:

[tex]P(X = 1) = \frac{e^{-0.04}(0.04)^{1}}{(1)!} = 0.038[/tex]

The probability of more than one shark attack is obtained as follows:

P(X > 1) = 1 - P(X ≤ 1)

In which:

P(X ≤ 1) = P(X = 0) + P(X = 1).

Then:

P(X = 0) = e^(-0.04) = 0.961.P(X = 1) = 0.038.

Thus:

P(X > 1) = 1 - (0.961 + 0.038) = 0.001.

For 100 years, the mean is of:

100 x 8/200 = 4.

Thus the probability of at least one attack is of:

P(X > 0) = 1 - e^(-4) = 0.982.

Model the data with a linear function using age 32 and 35. Then
predict the cost of life insurance for a female non-smoker of
age 40. Round to the nearest dollar.

Answers

To model the data with a linear function, we can use the two data points for ages 32 and 35 to find the slope and y-intercept of the line. Since the cost of life insurance for a female non-smoker at age 32 is $172 and the cost at age 35 is $182, the slope of the line is given by the formula:

$m = \frac{\text{cost at age 35} - \text{cost at age 32}}{\text{age 35} - \text{age 32}} = \frac{182 - 172}{35 - 32} = \frac{10}{3} = 3.33$

We can then use the point-slope formula to find the y-intercept of the line:

$y - y_1 = m(x - x_1)$

$y - 172 = 3.33(x - 32)$

To find the y-intercept, we can set $x = 0$ and solve for $y$:

$y - 172 = 3.33(0 - 32)$

$y - 172 = -105.76$

$y = 66.24$

Therefore, the equation of the line that models the data is given by:

$y = 3.33x + 66.24$

To predict the cost of life insurance for a female non-smoker of age 40, we can substitute 40 for $x$ in the equation above:

$y = 3.33(40) + 66.24$

$y = \boxed{239.44}$

Therefore, the predicted cost of life insurance for a female non-smoker of age 40 is $239.44.

(Round your answers to three decimal places.) (a) How fast is the distance from the television camera to the rocket changing at that moment? 480 ft/s (b) If the television camera is always kept aimed at the rocket, how fast is the camera's angle of elevation changing at that same moment? 0.002 rad/s

Answers

For the given height and distance  the answer of the following questions are:

a. Change in distance between the camera to the rocket at that moment is equal to 540ft/sec.

b. Change in the angle of elevation is equal to 0.144rad/sec.

As given in the question,

Let 'α' be the angle of elevation

'h' be the height of the rocket

'x' be the distance between the camera and the rising rocket.

a. Relation between x , h, and 4000 ft during launching pad is given by Pythagoras theorem:

x² = h² + 4000²

Differentiate with respect to time 't' we get,

2xdx/dt = 2hdh/dt + 0 __(1)

When h = 3000ft

x² = 3000² + 4000²

⇒x = 5000ft

dh/dt = 900ft/s

Substitute all values in (1) we get,

2(5000)dx/dt= 2(3000)(900)

⇒dx/dt = 5,400,000/ 10,000

⇒dx/dt = 540ft/sec.

b. tanα = h/4000 __(2)

when h = 3000ft

tanα = 3/4

⇒α = 0.6435

Differentiate (2) with respect to t we get,

sec²α dα/dt = (1/4000) dh/dt

⇒sec²(0.6435) dα/dt = (1/4000)(900)

⇒dα/dt = (0.225)/ 1.5625

⇒dα/dt = 0.144 rad/ sec.

Therefore, for the given height and distance the answer of the following questions are:

a. Change in distance between the camera to the rocket at that moment is equal to 540ft/sec.

b. Change in the angle of elevation is equal to 0.144rad/sec.

Using the Normal Distribution , the probability of landing in the circle on ground 10 times or less is 85.32 % , the correct option is (d) None of these   .

The term Normal Distribution is defined as a continuous probability distribution where the values lie in a symmetrical fashion mostly situated around mean .

it is given that ,probability(p) of landing marble on ground is 25% = 0.25

game is played for 30 rounds (n) = 30 ; q = 1 - 0.25 = 0.75 .

we know the mean (μ) = n×p = 30 × 0.25 = 7.5  ;

the standard deviation is (σ) = √n×p×q = √30×0.25×0.75  

= √5.625 = 2.38

By using Normal Distribution , X follows N(μ,σ²)

that is X follows N(7.5 , 2.38²) ;

we have to find P[X<10] = P[ (x-μ)/σ < (10 - 7.5)/2.38]

= P[ z < 2.5/2.38] = P[ z < 1.05 ] = 0.85314094 = 85.32 %

Work out the difference in minutes between 2 hour 35 minutes and 1 3/4 hours

Answers

Answer: The difference in minutes between 2 hours 35 minutes and 1 3/4 hours is 30 minutes.

Step-by-step explanation:

To find the difference in minutes between 2 hours 35 minutes and 1 3/4 hours, we can first convert 1 3/4 hours to minutes.

There are 60 minutes in 1 hour, so 1 3/4 hours is equal to 1 + 3/4 = 1 3/4 hours = 1.75 hours.

Since there are 60 minutes in 1 hour, 1.75 hours is equal to 1.75 * 60 = 105 minutes.

Then, we can subtract 105 minutes from 2 hours 35 minutes to find the difference in minutes:

2 hours 35 minutes - 105 minutes = 135 minutes - 105 minutes = 30 minutes

So, the difference in minutes between 2 hours 35 minutes and 1 3/4 hours is 30 minutes.

g use the formula for the sum of a geometric series to find the sum or state that the series diverges 100/81 10/9 1 9/10 81/100 729/1000

Answers

The sum of geometric series is 12.34 and the series is converges

According to the question,

Geometric series is  100/81 + 10/9 + 1 + 9/10 + 81/100 + 729/1000 + . . .

The given series looks like to be in geometric progression with constant ratio r

r = 2nd term/1st term = a2/a1

= (10/9) / (100/81)

=> 9/10

We know that if the ‘r’ is less than 1 then it is convergent

Here 9/10 < 1, it is convergent.

Clearly, this is the sum of an infinite geometric series.

Sum of infinite series in GP = a/(1 - r)

Where a is the first term, 9/10 is the common ratio.

Sum of the geometric series = (100/81) / (1 - 9/10)

=> (100 / 81) / ( 1 / 10)

=> 100 / 8.1

=> 12.34

Therefore, the given series is convergent and its sum is 12.34

The length of a rectangle is 5cm longer than its width. If the perimeter of the rectangle is 74cm , find its length and width.

Answers

Answer:

The width of the rectangle is 32cm and the length is 37cm.

Step-by-step explanation:

Let's call the width of the rectangle "w" and the length of the rectangle "l".We know that the perimeter of the rectangle is equal to 2 times the sum of the length and the width, or 2(w+l) = 74.We also know that the length is 5cm longer than the width, so we can set up the equation l = w + 5.We can substitute this expression for l in our first equation to get 2(w + (w + 5)) = 74.Combining like terms, we get 2w + 10 = 74.Dividing both sides by 2, we get w = 32.We can now use this value to find the length of the rectangle.Thus, the width of the rectangle is 32cm and the length is 37cm.

Linda enrolls for 10 credit hours for each of two semesters at a cost of $550 per credit-hour (tuition and fees) in addition, textbooks cost $350 per semester. round your answer to the nearest dollar.
A) $488 B) $150 C) $1463 D) $975

Answers

Linda enrolls in two semesters for a total of 20 credits at a cost of $550 per credit hour (tuition and fees), plus $350 for each semester's textbooks. $488 is the total cost for one month. The right response in this case is option A.

In economics, the total cost is the total of all expenses a company incurs in order to produce a particular level of production.

The total cost is the sum of all the expenses a firm has expended to create a specific level of output. Product managers can assess their overall profit margin by adding together their fixed and variable costs. The sum of the fixed and variable expenses is the total cost.

The total cost for one semester = 10(550) + 350

= 5850

Total cost for one month = 5850/12

= 487.5 = $488

let $c$ be a complex number. suppose there exist distinct complex numbers $r$, $s$, and $t$ such that for every complex number $z$, we have \[ (z - r)(z - s)(z - t)

Answers

There are four possible  values of C if there exist distinct complex numbers.

A complex number is an element of a number system that extends the real numbers with a specific element denoted i is called the imaginary unit . the equation every complex number can be expressed as,

             a + bi

where a and b are real numbers.

Let p(z) denote the cubic on the left-hand side; the right-hand side is then c3p(z/c). Write p(z)=z3+Az2+Bz+C so

z3 + Az2 + Bz + C ≡  z3+ cAz2 + c2Bz + c3C

⟹ (c−1)A =  (c2−1)B = (c3−1)C = 0.

Solving this we can find the possible values of C.

A real number can be said as a number that can be used to measure a continuous one-dimensional quantity such as a distance, duration or temperature. continuous means that values can have arbitrarily small variations. Every real number can be almost uniquely represented by an infinite decimal expansion.

Answers

We calculated 3-month weight moving average forecast = 0.417

What is weight moving average?

It is a statistical expression of calculating average forecast that allows to keep heavier weight with the most recent data.

How to calculate weight moving average?

Given, weights for the 3 months are 0.6, 0.3 and 0.1 where the first weight is used for the most recent month and the last weight is used for the least recent month.

the weighing factor will be n, n-1 and n-2

n is the number of periods and n=3

now, weight moving average = [W1 × n +W2 × (n-1) × W3 × (n-2)]/ [n+(n-1)+(n-2)]

         [0.6 x 3 +0.3 x 2 + 0.1 x 1]/ [3+2+1] = 0.417

hence, weight moving average is 0.417
