Answer:

-2 < x < 4.5

Step-by-step explanation:

Step 1: Add 1 to all parts/sections.

Step 2: Divide all parts/sections by 2.

Therefore, the range of possible values of x is -2 < x < 4.5.

Given

(3x + 7)(2x - 5) = 0

Equate each factor to zero and solve for x

3x + 7 = 0 ⇒ 3x = - 7 ⇒ x = - \frac{7}{3}

3\7

→ A

2x - 5 = 0 ⇒ 2x = 5 ⇒ x = \frac{5}{2}

2\5

→ B

Step-by-step explanation:

1000($1500(0.40)) = $600 000

450($1500(0.25)) = $168,750

600,000 - 168,750 = $431,250

$431,250 / 550 = 784.0909090... $784.09

$1500 + $784.09 = $2,284.09

Step-by-step explanation:

A square prism is a three-dimensional cuboid where the base and top are equal squares and the remaining 4 faces are rectangles.

to get the surface area of the package (that square prism) the size of the content inside is irrelevant and only there to confuse us.

the package has a base area of 16 in².

that means it also has a top (or cover) area of the same size : 16 in².

as top and bottom are squares, that means their areas are the square of their side lengths.

therefore, the side length of such a square is

s = sqrt(16) = 4 in

now we know also the dimensions of the 4 rectangles that are the side areas (faces) : 4 in × 4.25 in

the area of such a rectangle is

4 × 4.25 = 17 in²

so, the total surface area is (top and bottom + 4 side areas)

2×16 + 4×17 = 32 + 68 = 100 in²

The required coefficient of variation 23.44.

What is sample space?

A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space.

Given that,

The coefficient of variation for the sample,

CV = 100(s/x),

Where s is the standard deviation and x is the mean,

According to the provided formula,

The mean weight is 143.5 pounds,

And the standard deviation is 33.65 pounds.

Thus, after entering those values:

CV = 100 * (33.65/143.5)

CV ≈ 23.44

Therefore, for the sample weights in pounds that is given, the coefficient of variation is roughly 23.44.

Step-by-step explanation:

The formula for nCk is ...

  nCk = n!/(k!(n -k)!)

It always works out that nC0 = 1 and nC1 = n, and the sequence of numbers across a row of the diagram is symmetrical about the center.

This means you only need to calculate one value to finish filling your diagram.

  4C2 = 4!/(2!(2!)) = (4·3)/(2·1) = 6

You will find the pattern to be ...

Answer:

  B.  $8,144.47

Step-by-step explanation:

The compound interest formula is ...

  A = P(1 +r)^t

where r is the annual rate compounded annually for t years, applied to principal P.

  A = $5000(1 +0.05)^10 = $8144.47

After 10 years, there will be $8,144.47 in the account.

The equation of the function graphed below is f(x) = a(x - 2)² - 3 since the vertex is at (2, -3).

We have,

From the graph given,

The vertex is at (2, -3).

Now,

The vertex form of a quadratic function is given by:

f(x) = a(x - h)² + k

Where (h, k) is the vertex of the parabola.

Given the vertex (2, -3), we can plug in the values of h and k into the vertex form:

f(x) = a(x - 2)² - 3

Thus,

The equation of the function graphed below is f(x) = a(x - 2)² - 3

Step-by-step explanation: parenthese, exponent, multiplication, division, addition, subtraction

Answer:

You can follow the P.E.M.D.A.S.

Step-by-step explanation:

If you need an explanation for this, the P.E.M.D.A.S are a way to remember the Order of Operations. We can explain this with a simple equation, such as:

4/2+(3*2)-2^2

To begin with, we need to start with the Parentheses. Three times two is equal to six, so now the equation looks like this:

4/2+6-2^2

After that, you need to move onto the Exponents. Two to the power of two (marked with the ^) is four, so we replace 2^2 with a 4.

4/2+6-4

Next, we do the Multiplication and the Division. Since there's no multiplication involved with this particular problem, we'll go right onto the division. 4/2 is equal to two, so you replace that with a simple 2.

2+6-4

Now, lastly you wrap up by doing the Addition and the Subtraction. 2+6-4 is equal to 8-4, and the answer is ultimately 4. A reminder is that you always need to go left to right no matter what or else your solution will most likely be wrong.

Answer:

  $263.20

Step-by-step explanation:

The number not sold was ...

  620 -430 = 190

The cost for a container not sold was ...

  $0.78 -0.40 = $0.38

__

The cost of containers sold was ...

  $0.78 × 430 = $335.40

The cost of containers not sold was ...

  $0.38 × 190 = $72.20

The total cost for the 620 containers of milk was ...

  $335.40 +72.20 = $407.60

The total revenue from the 430 containers sold was ...

  $1.56 × 430 = $670.80

Step-by-step explanation:

Answer:

(2,3)

Step-by-step explanation:

- Substitute the equation for y instead of the y variable.

-3x - 2(5x - 7) = -12

-3x - 10x + 14 = -12

-13x = -26

x = 2

- Now substitute the value of x into the other equation.

y = 5x - 7

y = 5(2) - 7

y = 10 - 7

y = 3

Answer:

x = 2 and y = 3

Step-by-step explanation:

y = 5x - 7

-3x - 2y = -12

Substitute y into the second equation:

-3x - 2(5x-7) = -12

Simplify:

-13x = -26

x = 2

Substitute x into the first equation:

y = 5(2) - 7

y = 10 - 7

y = 3
