Answer: p.e.m.d.a.s

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.

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 ...

  each element in the diagram is the sum of the two above  it.

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

Then the profit was ...

  profit = revenue - cost

  profit = $670.80 -407.60 = $263.20

Additional comment

The calculation can be simplified to ...

  $1.16 × (number sold) - $0.38 × (number bought)

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

The possible values are anything between -7 and -4 so this means it would be either -5 or -6

Answer:

1113.75

Step-by-step explanation:

The formula for simple interest is as follows: Simple interest = principal balance x interest rate x term of the loan

P=4500

i= 0.055

t=4.5

multiplying them together we get

1113.75

The reason that this is simple interest is because compound interest increases over time as an exponential

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.
