part A Elliana and Isabella are exercising on a track. They are walking at a rate of 3 miles per hour. How far does Elliana go after 15 minutes of walking?

part B Now Isabella starts jogging and Elliana continues walking. Isabella is running at a rate of 4 miles per hour. Isabella runs 2 miles and then both girls stop exercising. What is the total distance in miles that Elliana walked on the track? Show work. Draw a picture if it helps.

Answers

Answer 1

Distance and displacement are the two quantities which are seem to mean the same but are distinctly different. The distance indicates how much an object covered during its motion whereas the displacement indicates how far out of place an object.

Here the total distance and the distance covered by Elliana is given as follows:

A. .15 min = .25 hrs

3 × .25 = .75 minutes

We have to find how long isabella to run 2 miles at 4 miles per hour:

2/4 = .5 hrs

Isabella can walk in .5 hrs at 3mph is:

.5 × 3 = 1.5 minutes

B. Total distance in miles that Elliana can travel is:

.75 + 1.5 = 2.25 minutes

given the recent economic downturn, only 60% in a graduating class of 250 will find employment in the first round of a job search. you have 20 friends who have recently graduated. assume that your friends represent a random sample. interpret the sampling distribution of the sample proportion of your friends who will find employment in the first round of a job search.

Answers

The sampling distribution of the sample proportion of your friends who will find employment in the first round of a job search will have a mean of 0.60 (60%) and a standard deviation of 0.071 (7.1%).

A sampling distribution is a probability distribution of a statistic obtained from a larger number of samples drawn from the same population.

The following are the characteristics of the sampling distribution:

It is a probability distribution.It is built up of a statistic derived from a random sample.It is for a specific statistic (such as the mean or proportion).It depends on the sample size.

The sampling distribution of the sample proportion of your friends who will find employment in the first round of a job search can be interpreted as follows:

Only 60% of the students in a graduating class of 250 will find employment in the first round of a job search. Suppose we take a sample of 20 friends who have recently graduated. Since it is a random sample, it is possible to obtain different values of the sample proportion of your friends who will find employment in the first round of a job search. The distribution of all the possible sample proportions is called the sampling distribution.

The mean of the sampling distribution is equal to the population proportion of 60%. The standard deviation of the sampling distribution can be determined using the formula:

standard deviation = √(p(1-p)/n),

Where p is the population proportion, and n is the sample size.

Standard deviation = √(0.60 x 0.40/20) ⇒ 0.012 (1.2%)

Therefore, the sampling distribution of the sample proportion of your friends who will find employment in the first round of a job search will have a mean of 0.60 (60%) and a standard deviation of 0.012 (1.2%).

for a second-order homogeneous linear ode, an initial value problem consists of an equation and two initial conditions. True False

Answers

The given statement "For a second-order homogeneous linear ordinary differential equation (ODE), an initial value problem (IVP) consists of an equation and two initial conditions" is True because  A second-order homogeneous linear ODE is an equation of the form ay''(t) + by'(t) + cy(t) = 0, where y(t) is the dependent variable, t is the independent variable, and a, b, and c are constants.

The equation is homogeneous because the right-hand side is zero, and it is linear because y(t), y'(t), and y''(t) are not multiplied or divided by each other or their higher powers. An IVP for this type of equation requires two initial conditions because the second-order ODE has two linearly independent solutions.

These initial conditions are typically given in the form y(t0) = y0 and y'(t0) = y1, where t0 is the initial time, and y0 and y1 are the initial values of y(t) and y'(t), respectively.

The two initial conditions are necessary to determine a unique solution to the second-order ODE. Without them, there would be an infinite number of possible solutions. By providing the initial conditions, you establish constraints on the solutions, which allow for a unique solution that satisfies both the ODE and the initial conditions.

In summary, an IVP for a second-order homogeneous linear ODE consists of an equation and two initial conditions, ensuring a unique solution to the problem.

Answers

Part A: Rebecca's credit card balance can be calculated using the equation x = (51 - 1) 0.02 if her finance charge is $51.

Part B: By making the purchase on the final day of the billing cycle rather than the first day, Rebecca will be able to avoid paying $27 in finance charges.

How do equations work?

A mathematical statement proving the equality of values between two or more mathematical expressions is called an equation.

Equation symbols (=) are used to represent equations.

A finance charge is what?

The interest and other fees levied on credit cards are included in a finance charge.

Typically, the finance charge is based on a stated APR (annual percentage rate).

The month's billing cycle lasts for 28 days.

Balance at current starting = x.

APR = 24%, or annual percentage rate.

The monthly percentage rate (MPR) equals 2% (24% divided by 12).

The final day's purchase cost $1,400.

$51 is the total finance fee for the month.

($1,400 x 2% x 1/28) = $1 finance fee for the last-minute purchase.

$50 ($51 - $1) serves as the initial balance's finance charge.

The starting balance at this time is x = $2,500 ($50 x 2%).

Current Beginning Balance Equation: x = 51 - 1 0.02

($1,400 x 2%) Equals $28 in total loan charges for the last-minute purchase.

Finance charge savings from buying on the last day equals $27 ($28 - $1).

By buying the $1,400 gift for her friend on the last day of the billing cycle rather than the first, Rebecca can avoid paying $27 in finance charges.

lloyd's cereal company packages cereal in 1 pound boxes (16 ounces). a sample of 25 boxes is selected at random from the production line every hour, and if the average weight is less than 15 ounces, the machine is adjusted to increase the amount of cereal dispensed. if the mean for 1 hour is 1 pound and the standard deviation is 0.1 pound, what is the probability that the amount dispensed per box will have to be increased?

Answers

The probability that the amount dispensed per box will have to be increased is 0.0062.

Consider the provided information.

Sample of 16 boxes is selected at random.

If the mean for 1 hour is 1 pound and the standard deviation is 0.1

1 Pound = 16 ounces , then 0.1 Pound = 16/10 = 1.6 ounces

Thus: μ = 16 ounces and σ = 1.6 ounces.

Compute the test probability

z= x−μ/σ/\(\sqrt{n}\)

z= 15-16/ 1.6/4

z= -1/ 0.4

z= -2.5

By using the table.

Probability p value = P(Z<-2.50) = 0.0062

Answers

The scale factor is 2.

A scale factor is defined as the ratio of the scale of a given original object to the scale of a new object that is its representation but of a different size (bigger or smaller).

J: (2,4) -- J' (4.8)

K: (1,1) -- K' (2,2)

L: (4,0) -- L' (8,0)

We need to find the scale factor.

Scale factor:

If a figure is dilated by factor   with origin as the center of dilation, then

P(x, y) = P1(kx, ky)

Using this rule, we get

J(2, 4) = P1(2k, 4k)

We have J1(4, 8)

On comparing both sides, we get

2k = 4 or 4k = 8

K = 4/2   or  k = 8/4

K = 2   or k = 2

In both cases, the value of the scale factor is k =2.

Therefore the scale of factor is 2

The measure of angle y is 116 ⁰.

What is the measure of angle y?

First we need to find the value of angle DCO and the value of angle DOC.

∠ DCO = 90 - 58⁰ ( angle subtended by diameter of a circle )

∠ DCO = 32⁰

line OC = OD = radius of the circle

∠ DCO = ∠ DOC = 32⁰

Now, the measure of angle y is calculated as follows;

∠ ODC + ∠ DCO + ∠ DOC = 180 ( sum of angles in a triangle )

y + 32 + 32 = 180

y + 64 = 180

y = 180 - 64

Answer:

Step-by-step explanation:

A kite is a quadrilateral (has four sides and four angles) with two pairs of congruent adjacent sides. The diagonals of a kite are perpendicular to each other.

To prove that quadrilateral ADBC is a kite, the diagonals of the kite have to be perpendicular to each other.

AD ⊥ BC.

Since adjacent sides are equal to each other, hence:

BC = BD, AC = AD

The coordinate of the vertices are A(11, 0), B(11, 26), C(0, 18) and D(22, 18)

\(BC=\sqrt{(0-11)^2+(18-26)^2} =13.6\ unit\\\\AC=\sqrt{(0-11)^2+(18-0)^2} =21.1\ unit\)

Find a vector equation with parameter t for the line of intersection of the planes x y z=2 and x z=0.

Answers

The vector equation with parameter t for the line of intersection of the planes x + y + z = 2 and x + z = 0 is r(t) = <0, 2, 0> - t<1, -1, 0>.

To find a vector equation with parameter t for the line of intersection of the planes x + y + z = 2 and x + z = 0, we can solve the system of equations formed by the planes.
First, let's solve for y in terms of x and z from the equation x + y + z = 2. Rearranging the equation, we have y = 2 - x - z.
Now, substitute this expression for y in the equation x + z = 0. We have x + (2 - x - z) + z = 2, which simplifies to 2 - z = 2.
Solving for z, we find z = 0.
Substituting z = 0 into the equation x + z = 0, we have x = 0.
Now that we have the values of x, y, and z, we can form a vector equation for the line of intersection as follows:
r(t) =  = <0, 2 - x - z, 0> = <0, 2, 0> - t<1, -1, 0>.

If 100mg of drug X is mixed with enough ointment to obtain 50 grams of mixture, what is the concentration of drug X in ointment (expressed as a ratio)?

Answers

The concentration of drug X in the ointment mixture is 2mg/g or 0.002. This means that for every gram of ointment, there are 2 milligrams of drug X present.


To find the concentration of drug X in the ointment mixture, we can calculate the ratio of the mass of drug X to the mass of the ointment. In this case, 100mg of drug X is mixed with enough ointment to obtain 50 grams of the mixture, resulting in a concentration of 2mg of drug X per gram of ointment.

Given:

Mass of drug X = 100mg

Total mass of the mixture = 50g

Step 1: Convert units

To ensure consistent units, we need to convert the mass of drug X from milligrams to grams. Since 1 gram equals 1000 milligrams, the mass of drug X is 0.1 grams.

Step 2: Calculate the concentration

The concentration of drug X in the ointment mixture is defined as the ratio of the mass of drug X to the mass of the ointment.

Concentration = Mass of drug X / Mass of ointment

In this case, the mass of drug X is 0.1 grams, and the mass of the ointment is 50 grams.

Concentration = 0.1g / 50g

Simplifying the expression, we get:

Concentration = 0.002

Therefore, the concentration of drug X in the ointment mixture is 0.002, which means there are 2 milligrams of drug X per gram of ointment.

In summary, the concentration of drug X in the ointment mixture is 2mg/g or 0.002, indicating that for every gram of ointment, there are 2 milligrams of drug X.
