Answer:

x = - 1 or x = 5

Step-by-step explanation:

(x - 2)² = 9 ( take the square root of both sides )

x - 2 = ± \(\sqrt{9}\) = ± 3 ( add 2 to both sides )

x = 2 ± 3

Then

x = 2 - 3 = - 1 or x = 2 + 3 = 5

Step-by-step explanation:

5x-6+7x+18=180

12x=180+6-18

12x=168

168÷12=14

X=14

for y

3y+11=7x+18(7×14+18)

3y+11=116

3y=116-11

3y=105

y= 35

Answer:

Step-by-step explanation:

L=2W-5

A=LW, using L from above gives you

A=(2W-5)W

A=2W^2-5W

2W^2-5W-A=0, since A=33yd^2

2W^2-5W-33=0

2W^2+6W-11W-33=0

2W(W+3)-11(W+3)=0

(2W-11)(W+3)=0, since W>0

W=11/2

W=5.5yd, since L=2W-5

L=6yd

So the dimensions are W by L, 5.5yd by 6yd

From the given equation y = 30(0.92)d, she should expect 193 phone calls after a week.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "="..

If the number of phone calls she should expect can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days, then we can calculate the expected amount phone calls after a week.

To determine how much phone calls she should expect after a week, substitute the value of d.

y = 30(0.92)d

where d = 1 week = 7 days

y = 30(0.92)(7)

y = 193.2

Rounding off to the nearest whole number,

y = 193

What initial investment must be made to accumulate $120000 in 12 years if the money is invested in a mutual fund that pays 14%

annual interest, compounded monthly?

Remember that

The compound interest formula is equal to

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

A=$120,000

t=12 years

r=14%=14/100=0.14

n=12

substitute in the given formula

The given function is C(x) = 936 + 80x + 0.12x^2, where x represents the number of mountain bikes produced daily. The average cost function is also given by C(x).
To make the mountain bike as affordable as possible, the company should target a production level of 333.33 mountain bikes daily, where the average cost function is at its minimum. Rounded to 2 decimal places, the answer is

c = 333.33.

First, let's correct the given cost function: C(x) = 936x + 80x^2 + 0.12x^3. Now, we'll use the terms "function," "average," and "increases."

To find the average cost function, we need to divide the total cost function, C(x), by the number of mountain bikes produced daily, x. Let A(x) represent the average cost function:

A(x) = C(x) / x

Now, let's substitute C(x) into this equation:

A(x) = (936x + 80x^2 + 0.12x^3) / x

Simplify by canceling out an x term:

A(x) = 936 + 80x + 0.12x^2

To find the production level c where the average cost function decreases and then increases, we need to find the minimum point on the A(x) curve. To do this, we'll differentiate A(x) with respect to x to obtain the first derivative:

A'(x) = 80 + 0.24x

Now, set the first derivative equal to zero and solve for x:

80 + 0.24x = 0

0.24x = -80

x = c = -80 / 0.24

Round to 2 decimal places:

c ≈ 333.33

So, to make the mountain bike as affordable as possible, the company should target a production level of approximately 333.33 mountain bikes daily.

Answer:

ur welcoem

Step-by-step explanation:

To determine the probability that player A eventually wins all the money, we can consider the possible scenarios that lead to this outcome.

Player A can win in the first game, taking $1 from player B. This happens with a probability of 0.35.

Alternatively, player A can lose the first game, leaving both players with $3 each. In this case, the game continues and we need to consider the probability of player A eventually winning all the money from this point.

The probability of player A eventually winning all the money, given that they didn't win the first game, can be calculated as the probability of player A winning the next game multiplied by the probability of player A eventually winning all the money from that point.

The probability of player A winning the next game is 0.35 (since it's the same for each game).

Therefore, the overall probability of player A eventually winning all the money can be calculated as:

P(A wins all money) = 0.35 + 0.65 * P(A wins all money)

Simplifying the equation:

P(A wins all money) = 0.35 + 0.65 * P(A wins all money)

0.35 * P(A wins all money) = 0.35

P(A wins all money) = 0.35 / 0.35

P(A wins all money) = 1

Hence, the probability that player A eventually wins all the money is 1. This means that player A is guaranteed to win all the money in the long run.

X and Y are not independent.

P(Y > 2X) = 3/16.

Marginal pdf of X = 12x(1-x)² for 0 < x < 1

(a) To determine if X and Y are independent, we need to check if the joint pdf can be factored into the product of the marginal pdfs:

f(x,y) = 24xy if 0 < x, 0 < y, x + y < 1, and zero otherwise.

Marginal pdf of X can be calculated by integrating the joint pdf over the all possible values of y:

f(x) = ∫ f(x,y) dy from 0 to 1-x

= ∫ 24xy dy from 0 to 1-x

= 12x(1-x)² for 0 < x < 1

Similarly, the marginal pdf of Y can be found by integrating the joint pdf over all possible values of x:

f(y) = ∫ f(x,y) dx from 0 to 1-y

= ∫ 24xy dx from 0 to 1-y

= 12y(1-y)² for 0 < y < 1

To check for independence, we need to verify if f(x,y) = f(x)f(y) for all x and y. However, if we multiply the marginal pdfs, we get:

f(x)f(y) = 144xy(1-x)²(1-y)² for 0 < x < 1 and 0 < y < 1

This is not the same as the joint pdf, so X and Y are not independent.

(b) To find P(Y > 2X), we need to integrate the joint pdf over the region where Y > 2X:

P(Y > 2X) = ∫∫ f(x,y) dA over the region where Y > 2X

= ∫∫ 24xy dA over the region where Y > 2X

= ∫∫ 24xy dxdy over the region where 0 < y < 2x and x+y < 1

= ∫[0,1/2] ∫[y/2,1-y] 24xy dxdy

= 3/16

Therefore, P(Y > 2X) = 3/16.

(c) The marginal pdf of X is given by:

f(x) = ∫ f(x,y) dy from 0 to 1-x

Answer:

What are you asking?

To draw the supply and demand for labor in a market in equilibrium, and illustrate the impact of a labor union, we can use a standard supply and demand graph with quantity of labor (Q) on the x-axis and wage (W) on the y-axis.

Market in Equilibrium:

In a competitive labor market, the supply of labor represents the quantity of workers willing and able to work at various wage levels. The demand for labor represents the quantity of workers that firms are willing to hire at various wage levels. In equilibrium, the supply and demand curves intersect.

Let's assume that at the equilibrium, the wage is labeled as We and the quantity of labor is labeled as Qe.

Graphically, the supply curve (S) slopes upward from left to right, indicating that higher wages incentivize more workers to enter the labor market. The demand curve (D) slopes downward from left to right, indicating that higher wages result in fewer workers being demanded by firms.

Place the equilibrium point (We, Qe) where the supply and demand curves intersect on the graph.

Impact of a Labor Union:

When a labor union represents workers in the industry, it can negotiate for better wages and working conditions on behalf of its members. This can shift the supply and/or demand curve.

a. Shift in the Supply Curve:

If the labor union successfully negotiates higher wages for its members, it can result in an upward shift of the supply curve. This shift represents an increase in the quantity of labor supplied at each wage level.

Draw a new supply curve (S') above the original supply curve. The new supply curve should intersect the demand curve (D) at a higher wage level (Wu) and a greater quantity of labor (Qu).

b. Shift in the Demand Curve:

If the labor union's demands result in higher production costs for firms, it can lead to a decrease in labor demand. This can cause a leftward shift of the demand curve.

Draw a new demand curve (D') to the left of the original demand curve. The new demand curve should intersect the supply curve (S) at a lower wage level (Wd) and a lower quantity of labor (Qd).

Label the new equilibrium point with a labor union as (Wu, Qu).

Note: The specific shift and its impact (supply or demand) depend on various factors and the specific circumstances of the labor union's actions. The above explanation provides a general example.

By graphically illustrating the changes in the labor market due to the presence of a labor union, you can visually see the impact on the equilibrium wage and quantity of labor.

You will need 5.6 pounds of the candy that sells for $3.10/lb and (9.6 - 5.6) = 4 pounds of the candy that sells for $5.50/lb to obtain the desired candy mixture.

Let's assume you need x pounds of the candy that sells for $3.10/lb and (9.6 - x) pounds of the candy that sells for $5.50/lb to obtain the desired mixture.

To solve this problem, we can set up the following equation based on the total cost and total weight of the mixture:

(3.10 * x) + (5.50 * (9.6 - x)) = 4.10 * 9.6

Let's solve this equation to find the value of x:

3.10x + 5.50(9.6 - x) = 4.10 * 9.6

3.10x + 52.8 - 5.50x = 39.36

-2.40x = 39.36 - 52.8

-2.40x = -13.44

x = (-13.44) / (-2.40)

x = 5.6

Therefore, you will need 5.6 pounds of the candy that sells for $3.10/lb and (9.6 - 5.6) = 4 pounds of the candy that sells for $5.50/lb to obtain the desired candy mixture.

It will take approximately 9.56 years for the money to double in a deposit account paying 7.25% compounded continuously.

a) The time it takes to double your money in deposit account paying 10% compounded semiannually can be calculated using the formula for compound interest which is:

A=P(1+r/n)^(nt)

Where:A= amount

P= principal (starting amount)

R= rate of interest per year

T= time (in years)

N= number of times interest is compounded per year For a deposit account paying 10% compounded semiannually:

R=10%/year

= 0.1/2

= 0.05/6 months

T= time (in years)

P= principal (starting amount)

= 1 (since we're looking for when it doubles)

N= number of times interest is compounded per year

= 2 (since it's compounded semiannually)

Using the formula:

A = P(1 + r/n)^(nt)²

= 1(1 + 0.05/2)^(2t)²

= (1.025)²t²/1.025²

= t5.512

= t

Therefore, it will take approximately 5.5 years for the money to double in a deposit account paying 10% compounded semiannually.

b) The time it takes to double your money in deposit account paying 7.25% compounded continuously can be calculated using the formula:

A = P*e^(rt)

Where:A= amount

P= principal (starting amount)

R= rate of interest per year

T= time (in years)Using the formula:A = P*e^(rt)2 = 1*e^(0.0725*t)ln(2)

= 0.0725*tln(2)/0.0725

= t9.56 years

Therefore, it will take approximately 9.56 years for the money to double in a deposit account paying 7.25% compounded continuously.
