The amount that was invested in each account is:

Maricopa Success invested $47,858 in stocks.

Maricopa Success invested $63,571 in bonds.

Maricopa Success invested $47,571 in CDs.

Let c represent Cds

Let b represent bonds

Let s represent stocks

Equations:

b = c + 15000

s = 160000 - b - c = 160000 - c - 15000 - c = -2c + 145,000

0.08(-2c + 145000) + 0.036(c + 15000) + 0.04c = 7520

-0.16c + 11600 + 0.036c + 540 + 0.04c = 7520

-0.084c = -4,080

Divide both side by -0.084

c = -4,080 / 0.084

c= $48,571 (CDs)

b = 48,571+ 15000

b=$63,571 (bonds)

s = 160,000 - $63,571- 48,571

s= $47,858 (stock)

Therefore Maricopa Success invested $47,858  in stocks,Maricopa Success invested $63,571 in bonds and Maricopa Success invested $47,571 in CDs.

What is quadratic regression?

A statistical method called quadratic regression is used to identify the parabola equation that best fits a given collection of data. Finding the equation of the straight line that most closely fits a collection of data is the goal of this sort of regression, which is an extension of simple linear regression.

The equation of the parabola that best fits a collection of data is the process of a quadratic regression. As a consequence, we arrive at the equation y=ax2+bx+c where a≠0. The least squares approach is the most effective way to manually locate this equation.

Answer:

Step-by-step explanation:

To determine the total cost of the DVD, you need to calculate the amount of sales tax and add it to the cost of the DVD.

The sales tax is equal to the cost of the DVD multiplied by the sales tax rate:

Sales tax = $18.99 * 6.5% = $1.23

To determine the total cost, you need to add the cost of the DVD to the sales tax:

Total cost = $18.99 + $1.23 = $20.22

So the total cost of the DVD is $20.22.

Fun fact-

What is Inverse of a Function ?

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.

The output of a function is returned by the inverse function, which also returns the initial value.

If f and g are inverse functions, then f(g(x)) = g(f(x)) = x. The initial value is fetched via a function that is its inverse.

For instance, f(x) = 2x + 5 = y

Therefore, the inverse of f is g(y) = (y-5)/2 = x. (x).

on the number line, 2.0 is to the right of 2, and multiplying 2.0 by 10 moves it 10 times as far to the right as 2.0 is from 2. This is why 2 is 10 times the value of 2.0.

What is the number line?

The number line is a visual representation of the set of all real numbers, which are the numbers that can represent any value on the continuous number scale, including fractions and decimals. On the number line, each point corresponds to a specific real number.

The number 2 is represented by a point on the number line, as is the number 2.0. These two numbers are different because 2.0 is a decimal number, while 2 is a whole number.

2 is 10 times the value of 2.0 if you multiply 2.0 by 10. This is because multiplying a number by 10 shifts its decimal point one place to the left, which increases its value by a factor of 10. For example, if you multiply 2.0 by 10, you get 20.0, which is 10 times the value of 2.0.

Hence, on the number line, 2.0 is to the right of 2, and multiplying 2.0 by 10 moves it 10 times as far to the right as 2.0 is from 2. This is why 2 is 10 times the value of 2.0.

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.

Given expression:
