An investment company provides strategies for improving return on your investment. It believes that it can increase a customer’s returns by 2. 3%. Which statistical method would be best to use in this situation?

1 divided by 2/6 is equal to 3.

Division is a mathematical operation used to divide one number (the dividend) by another number (the divisor) to find out how many times the divisor is contained within the dividend

To divide 1 by 2/6, we need to find out how many times the denominator (2/6) fits into the numerator (1).

One way to approach this is to convert the fraction 2/6 to an equivalent fraction with a denominator of 1. To do this, we can multiply both the numerator and denominator of 2/6 by the same number, in this case 3:

2/6 = (23)/(63) = 6/18

Now, we can divide 1 by 6/18:

1 ÷ 6/18

= 1 x 18/6 (reciprocal of 6/18 is 18/6, which is equivalent to 3)

= 3

The answer: no real solutions to this equation

To solve the equation, we need to find a common denominator for all of the fractions on the left side of the equation. The common denominator will be (y-2)(y-3), so we will multiply each fraction by the appropriate factor to get the common denominator.

[tex]y/y -2y+ 4/y-3 = 4/ y2-5y+6[/tex]

[tex]y(y-3)/(y-2)(y-3) - 2y(y-2)/(y-2)(y-3) + 4(y-2)/(y-2)(y-3) = 4/(y-2)(y-3)[/tex]

Now we can combine the fractions on the left side of the equation:

[tex](y2-3y-2y2+4y+4y-8)/(y-2)(y-3) = 4/(y-2)(y-3)[/tex]

Simplifying the numerator on the left side gives us:

[tex](-y2+5y-8)/(y-2)(y-3) = 4/(y-2)(y-3)[/tex]

Now we can cross-multiply and simplify:

[tex](-y2+5y-8) = 4[/tex]

[tex]-y2+5y-12 = 0[/tex]

To solve this equation, we can use the quadratic formula:

[tex]y=\left(-5\pm \sqrt{52-4\left(-1\right)\left(-12\right)}\right)[/tex]

[tex]y=\left(-5\pm \sqrt{25-48}\right)[/tex]

[tex]y=\left(-5\pm \sqrt{-23}\right)[/tex]

Since the square root of a negative number is not a real number, there are no real solutions to this equation. Therefore, the answer is no solution.

Purchasing 3 points and reducing their interest rate, Lenny and Lisa will save 84,541.84 in interest over the life of the loan.

To calculate the break-even point on their mortgage, we need to determine how much Lenny and Lisa paid for the points and how much they save on their interest rate over the life of the loan.

First, we need to determine how much Lenny and Lisa paid for the points. One point is equal to 1% of the total loan amount, so 3 points is equal to 3% of 675,250:

3 points = 3% x 675,250 = 20,257.50

Next, we need to calculate how much Lenny and Lisa save on their interest rate by purchasing the points. Their original interest rate was 7.25%, but they were able to reduce it to 6.875% by purchasing 3 points. This means they save 0.375% on their interest rate.

To calculate how much they save over the life of the loan, we need to use an amortization schedule. An amortization schedule shows how much of each payment goes towards interest and how much goes towards principal, and it also shows the remaining balance on the loan after each payment.

Using an online mortgage calculator, we can generate an amortization schedule for Lenny and Lisa's loan. Based on this schedule, they will pay a total of 931,231.40 in interest over the life of the loan if they keep their original interest rate of 7.25%. If they reduce their interest rate to 6.875%, they will pay a total of 846,689.56 in interest over the life of the loan.

This means that by purchasing 3 points and reducing their interest rate, Lenny and Lisa will save 84,541.84 in interest over the life of the loan.

To determine the break-even point on their mortgage, we divide the cost of the points by the amount they save on their interest rate per year.

Answer:

An exponential function in the form of y = a(m) x is of the form:

y = a * m^x

where "a" is a constant, "m" is a positive constant (the base of the exponential), and "x" is the independent variable.

To determine the exponential function in this form, you need to have some information about the function, such as its value at a particular point or its rate of growth.

Here are the general steps to determine the exponential function in the form of y = a(m) x:

Determine the value of "a" by plugging in the known value of "y" and "x" into the equation.

Determine the value of "m" by solving for it using the given information.

For example, let's say you are given that the function passes through the point (2, 8) and has a growth rate of 3. To determine the exponential function in the form of y = a(m) x, you would follow these steps:

Plug in the values of x and y into the equation:

8 = a * m^2

Solve for "a" by isolating it on one side of the equation:

a = 8 / m^2

Use the given growth rate of 3 to find the value of "m":

m = 1 + r = 1 + 0.03 = 1.03

Plug in the value of "m" and the value of "a" you found in step 2 into the equation:

y = (8 / 1.03^2) * 1.03^x

Simplifying this equation gives:

y = 7.514 * 1.03^x

So the exponential function in the form of y = a(m) x that passes through the point (2, 8) and has a growth rate of 3 is y = 7.514 * 1.03^x.

Step-by-step explanation:

here is a more detailed explanation of the steps involved in determining an exponential function in the form of y = a(m) x:

Determine the value of "a" by plugging in the known value of "y" and "x" into the equation.

In the equation y = a(m) x, "a" is a constant that represents the value of y when x is equal to 0. So to find the value of "a", we need to know the value of y for a specific value of x, other than 0.

Using the addition method the solution to the system is (x,y) = (14/3, 7/3) and using the substitution method the solution to the system is (x,y) = (7,7).

Using the addition method, we can rearrange the equations so that one of the variables cancels out:

y=2x-7  ->  -2x + y = -7
y=4x-21  ->  -4x + y = -21

Now, we can add the two equations together to eliminate the y variable:

-2x + y = -7
-4x + y = -21
______________
-6x = -28

Next, we can solve for x:

x = 28/6 = 14/3

Now, we can substitute this value of x back into one of the original equations to find y:

y = 2x - 7 = 2(14/3) - 7 = 28/3 - 21/3 = 7/3

So the solution to the system is (x,y) = (14/3, 7/3).

Using the substitution method, we can substitute one equation into the other to eliminate one of the variables. For example, we can substitute the first equation, y=2x-7, into the second equation, y=4x-21:

2x-7 = 4x-21

Next, we can rearrange the equation to solve for x:

2x = 14
x = 7

Now, we can substitute this value of x back into one of the original equations to find y:

y = 2x - 7 = 2(7) - 7 = 7

So the solution to the system is (x,y) = (7,7).

In conclusion, we can solve the system y=2x-7 and y=4x-21 using either the addition method or the substitution method to find the solution (x,y).

For your tree, the z-score is:

z = (44.7 - 56.6) / 9.9 = -1.198

Using the standard normal table, the probability that the height of a randomly selected tree is as tall as yours or shorter is 0.1151.

For your neighbor's tree, the z-score is:

z = (74.4 - 56.6) / 9.9 = 1.798

Using the standard normal table, the probability that the height of a randomly selected tree is at least as tall as hers is 1 - 0.9638 = 0.0362.

If the ground already has an elevation of  15 degree. The degree that the ladder need to be set is 65.4 degrees.

Angle at which the ladder is set from the horizontal =  x.

Angle between the ladder and the ground =  (75 - 15 + x) degrees

Using trigonometry, we can write the equation:

tan(75 - 15 + x) = 10 / L

where:

L=  length of the ladder.

Simplifying the left-hand side using the trigonometric identity for the tangent of the difference of two angles, we get:

tan(60 + x) = 10 / L

Multiplying both sides by L, we get:

L * tan(60 + x) = 10

Dividing both sides by tan(60 + x), we get:

L = 10 / tan(60 + x)

Using a calculator, we can evaluate the right-hand side to be:

L = 10 / tan(60 + x) ≈ 5.768 / tan(x)

So, the equation we need to solve for x is:

5.768 / tan(x) = L

Substituting the value of L obtained from the previous problem, we get:

5.768 / tan(x) = 2.68

Multiplying both sides by tan(x), we get:

5.768 = 2.68 tan(x)

Dividing both sides by 2.68, we get:

tan(x) ≈ 2.153

Using a calculator, we can find the value of x that satisfies this equation by taking the inverse tangent (tan^-1) of both sides:

x ≈ 65.4 degrees

Therefore, the ladder needs to be set at an angle of approximately 65.4 degrees from the horizontal in order to reach a height of 10 feet when the ground already has an elevation of 15 degrees and the ladder is placed at a 75-degree angle with the ground.

Answer: Hence, the width of the path is 4 meters.

First we should find the area of the pool. Our width is 14 and our length is 18. In order to find the area, we must multiply these two numbers. 14 times 18 is 252. This means that the area of the pool is 252.

Since we know that one side of the pool is 18 and one side is 14, we can write out the equation below.

572= (18+2x)(14+2x)

The first thing we should do is combine like-terms.Our equation would now be as below.

x^2+16-80=0

Next we would take our quadratic equation- x=-b+-√b2-4ac/2a and fill it in with the numbers that we had in the first equation, our equation would be like below.  A=1   B=16   C=-80

x=-16+-√16^2-4* 1 * -80 /2 * 1

When then simplify our equation leaving us with x=-16+-√16^2-4*1(-80)/2 * 1, which broken down is x=-16+-√+-24/2.

Lastly we must subtract and add to receive our two answers.

One side is 4 and the other is -20. Since the width of the walk cannot not be a negative number, we know that the width of the path is 4 meters.

Hence, the width of the path is 4 meters.
