Step-by-step explanation:

the coeffient of variation, expressed as a percent, is used to describe the standard deviation relative to the mean. It allows us to compare variability of data sets with different measurement units and is calculated as coefficient of variation =100(s/x) Find the coefficient of variation for the following sample weights in pounds 130,127,186,105,197,153,172,150,116,125

Answers

I think it Waugh’s about 20 pounds or 125 I’m not sure

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.

Plz help! Plzzzzz Solve systems of Equations by substitution
y= 5x - 7

Slove step by step​

Answers

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

Answer:

See below

Step-by-step explanation:

The first part solved only. The second part is incomplete.

Using the information we build the equation for salary calculation:

S(x) = (x - 2014)*6000 + 250000, where S is the annual salary at year x, provided x > 2014

Use the equation and work out salary:

S(2015) = 1*6000 + 250000 = 256000S(2016) = 2*6000 + 250000 = 262000S(2018) = 4*6000 + 250000 = 274000S(2020) = 6*6000 + 250000 = 286000S(2021) = 7*6000 + 250000 = 292000

Need help on order of operations

Answers

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.

I hope this helps! Marking as Brainliest would be highly appreciated. Have a wonderful day. :)

A store received 620 containers of milk to be sold by March 1. Each container cost
the store $0.78 and sold for $1.56. The store signed a contract with the distributor in
which the distributor agreed to a $0.40 refund for every container not sold by March
1. If 430 containers were sold by March 1, how much profit did the store make?

Answers

9514 1404 393

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)
