What is an Equation?

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 first equation be represented as A

Now , the value of A is

x + 6y = 10   be equation (1)

Let the second equation be represented as B

Now , the value of B is

-x + 3y = -15   be equation (2)

On simplifying the equations , we get

Adding equation (1) and equation (2) , we get

6y + 3y = 10 - 15

9y = -5

Divide by 9 on both sides of the equation , we get

y = - ( 5/9 )

Substitute the value of y in equation (1) , we get

x - 30/9 = 10

Adding 30/9 on both sides of the equation , we get

x = 10 + 30/9

x = 120/9

Hence , the value of x and y are 120/9 and -5/9 respectively

The example given is most likely an example of quota sampling.

Quota sampling is a sampling method that involves the selection of participants based on specific pre-determined characteristics to ensure that the sample adequately represents the population. The goal is to get 200 responses, so they set a target to have ten Hispanic individuals take the taste test, as they are around 5% of the student population.

They also attempted to ensure that they had enough respondents of different genders and ethnicities by dividing them by age and race. Quota sampling is used when random sampling is difficult to implement, either because of financial or practical constraints, or when trying to obtain certain subgroups of people for study.

A certain wire stretches 0.90 cm when outward forces with magnitude F are applied to each end. The same forces are applied to a wire of the same material but with three times the diameter and three times the length. The second wire stretches:

Answers

The length of the second wire stretches when the same forces are applied to it is given by option A. 0.30 cm .

Length of the wire = 0.90cm

let us consider the concept of Young's modulus also known as the modulus of elasticity.

Young's modulus is a measure of the stiffness or rigidity of a material.

It quantifies how much a material deforms under a given force.

The equation for Young's modulus is as follows,

E = (F/A) / (ΔL/L)

Where,

E is Young's modulus

F is the applied force

A is the cross-sectional area of the wire

ΔL is the change in length of the wire

L is the original length of the wire

The first wire stretches by 0.90 cm

and the forces applied to both wires are the same,

Use this information to determine the Young's modulus of the material.

Let us assign some variables,

ΔL₁= 0.90 cm change in length for the first wire

L₁ = original length of the first wire

A₁ = cross-sectional area of the first wire

Since the forces applied to both wires are the same,

Assume that the stress force per unit area is the same for both wires. This implies,

(F/A₁) / (ΔL₁/L₁) = (F/A₂) / (ΔL₂/L₂)

The second wire has three times the diameter and three times the length of the first wire.

This means the cross-sectional area A₂ of the second wire will be nine times the cross-sectional area A₁ of the first wire.

Mathematically,

A₂ = 9A₁

Similarly, the length L₂ of the second wire is three times the length L₁ of the first wire,

L₂ = 3L₁

Substituting these values into our equation, we have,

(F/A₁) / (ΔL₁/L₁) = (F/(9A₁)) / (ΔL₂/(3L₁))

Simplifying further, we get,

⇒ 1 / (ΔL₁/L₁) = 1/9 / (ΔL₂/(3L₁))

⇒ L₁ /ΔL₁= 1/9 × 3L₁/ΔL₂

⇒ 1/ ΔL₁ = ( 3/9) ( 1 / ΔL₂)

Since ΔL₁ =0.90 cm  

Substitute these values and solve for ΔL₂,

⇒1/ 0.90 cm ₁ = ( 3/9) ( 1 / ΔL₂)

⇒ΔL₂ = (0.90 cm ) × (3/9)

⇒ΔL₂= 0.90 cm × (1/ 3)

⇒ΔL₂ = 0.30 cm

Therefore, the second wire stretches by option A. 0.30 cm  when the same forces are applied to it.

Answers

To solve the investment problem and determine how the retiree should invest her money to maximize expected earnings, we can set up a linear programming problem using the given data.

Let's define the decision variables as follows:

xM: Amount invested in municipal bonds (in dollars)

xR: Amount invested in real estate (in dollars)

xβ: Amount invested in blue chip stocks (in dollars)

xJ: Amount invested in junk bonds (in dollars)

xG: Amount invested in grain futures (in dollars)

The objective is to maximize expected earnings, which can be represented as:

0.06xM + 0.08xR + 0.1xβ + 0.12xJ + 0.15xG

Subject to the following constraints:

xM + xR + xβ + xJ + xG ≤ 250,000 (total investment cannot exceed $250,000)

xR / 100,000 + 1.5xβ / 100,000 + 2.5xJ / 100,000 + 5xG / 100,000 ≤ 5 (total management hours per week cannot exceed 5)

xM, xR, xβ, xJ, xG ≥ 0 (investment amounts cannot be negative)

Using Excel or any other linear programming software, we can input these constraints and the objective function to obtain the optimal solution. However, based on the provided information from Maple, the solution is as follows:

xM = $27,500

xR = $125,000

xβ = 0

xJ = 0

xG = 0

This means that the retiree should invest $27,500 in municipal bonds and $125,000 in real estate to maximize her expected earnings. No investment should be made in blue chip stocks, junk bonds, or grain futures according to this solution.

Genna wants to have a magician for her birthday party. She has $154 to spend. To have a magician come, there is an initial fee of $46, plus $27 per hour. How many hours can Genna have the magician stay?

Answers

Given statement solution is :- Genna can have the magician stay for 4 hours within her budget.

To determine the number of hours Genna can have the magician stay, we need to calculate how many hours can be covered within her budget.

Let's assume Genna can have the magician stay for "x" hours. The initial fee is $46, and the magician charges an additional $27 per hour. Therefore, the total cost for "x" hours can be calculated as:

Total cost = Initial fee + (Hourly rate * Number of hours)

Total cost = $46 + ($27 * x)

Genna's budget is $154. So we can set up the equation:

$154 = $46 + ($27 * x)

To solve for "x," we need to isolate the "x" variable. Let's rearrange the equation:

$27 * x = $154 - $46

$27 * x = $108

Dividing both sides by $27:

x = $108 / $27

x = 4

Therefore, Genna can have the magician stay for 4 hours within her budget.

2327 is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.

Given that,

TV viewers frequently doubt the validity of particular advertising. In an attempt to counter their critics, a large advertiser wants to determine the true proportion of consumers who believe what is depicted in ads. About 40% of individuals examined, according to preliminary studies, seem to believe what is depicted in advertisements.

We have to find what is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.

We know that,

Let

Population proportion (p)= 0.40

Margin of error = 2% = 0.02

Confidence level = 95% = 0.95

α = 1- 0.95 = 0.05

α/2 = 0.025

Let's find out the Z critical value using excel for the 95% confidence level,

Use the following excel command.

= ABS(NORMSINV(α/2))

= ABS(NORMSINV(0.025))

We will get, Z critical value = 2.17009

Sample size (n) = p(1-p)×(Zα/2)/E

n = 0.40(1-0.40)({2.17009}÷{0.05})²

Sample size (n) = 2327

corn and $4 for 10 ears of corn using

another representation.

Answers

The proportional relationship between the price and quantity of ears of corn can be represented using a table or a graph, showing how the price and quantity vary in a consistent manner.

One way to represent the proportional relationship between the price and quantity of ears of corn is by using a table:

Price (in dollars) Quantity (in ears of corn)

             2             5

             4             10

This table shows the corresponding values of the price and quantity.

As we can observe, when the price is $2, the quantity is 5 ears of corn, and when the price is $4, the quantity is 10 ears of corn.

The relationship is proportional because as the price doubles, the quantity also doubles.

Another representation of this proportional relationship is through a graph.

We can plot the points (2, 5) and (4, 10) on a coordinate plane, where the x-axis represents the price and the y-axis represents the quantity.

By connecting these two points with a straight line, we can visualize the proportional relationship.

The line will pass through the origin (0, 0) since zero price corresponds to zero quantity.

The slope of the line will indicate the rate of change between price and quantity.

chloe lives in an area where she runs the air conditioner during the 4 hottest months of the year. the air conditioner runs for 7 hours per day at a cost of 21 cents per hour. how much does she spend per year on utility bills for the air conditioner?(assume there are 30 days in each month)

Answers

Chloe runs her air conditioner for a total of 4 months, or 120 days. Chloe spends $176.40 per year on utility bills for the air conditioner during the four hottest months.

The reason for this expense is the need for cooling during these months, and the cost associated with running the air conditioner for 7 hours per day at a rate of $0.21 per hour.

To calculate the annual cost of running Chloe's air conditioner, we need to consider the number of hours per day, the cost per hour, and the number of days the air conditioner is used.

1. First, let's determine the total number of hours the air conditioner runs during the four hottest months:
7 hours/day * 30 days/month * 4 months = 840 hours

2. Now, we can calculate the total cost by multiplying the number of hours by the cost per hour:
840 hours * $0.21/hour = $176.40

At 7 hours per day, that's a total of 840 hours of use. At a cost of 21 cents per hour, Chloe spends 0.21 x 840 = $176.40 per year on utility bills for her air conditioner.
