For the purpose of determining the value of its end-of-year inventory, a clothing store creates a list at the end of the year of

every item currently in stock along with each item's wholesale price. Which of the following is the best description of the end-of-the-year activity?
a. An experiment, because the items are treatments and wholesale prices are responses.
b. An experiment, because the store does not know the total wholesale price of all the items.
c. A sample survey, because the store wants to estimate the value of all items for the entire year.
d. A sample survey, because the items currently in the store at the end of the year are a random sample of all items in the store for the entire year.
e. A census, because the wholesale prices of all items are listed.

Answer:

e. A census, because the wholesale prices of all items are listed.

Step-by-step explanation:

A census encompasses collecting data of an entire population as well evaluation of the characteristics of an entire population. Every item currently in store alongside their wholesale price was included in the survey here. None was excluded. So we cannot call the activity a sample survey. Since all items were counted, the best description to give to this activity is "a census".

Select all of the following that are quadratic equations.
deff fn [24]
What you want to do is solve all of these so that it equals to 0 on one side. The ones that are a quadratic will have x^2

x^2 - 2x = 4x + 1
x^2 - 6x - 1 = 0
Yes this is a quadratic

x^3 - 6x^2 + 8 = 0
No this is not a quadratic because the highest power of x is to the power of 3

5x - 3 = 0
No it is not a quadratic because it does not have x^2

2x^2 + 12x = 0
Yes because there's x^2

5x - 1 = 3x + 8
2x - 9 = 0
No because no x^2

9x^2 + 6x - 3 = 0
Yes because there's x^2

A man is sixteen years older than his father, if the total age is 57. How old is the son and the father?​
Alex Ar [27]

Answer:

The son is 20 and a half years old.

The father is 36 and a half years old.

Step-by-step explanation:

We can solve this easily by turning it into an equation.

Let the mans age be y and the fathers age be x.

y+x=57

x=y+16

We can use the substitution method to solve for the first equation.

y+(y+16)=57

Now we only have one variable to solve for. Add like terms.

2y+16=57

Subtract 16 on both sides.

2y=41

Divide both sides by 2 to isolate y.

y=20.5

Now substitute 20.5 for y to solve for x.

20.5+x=57

Subtract 20.5 from both sides.

x=36.5

<em>The son is 20 and a half years old.</em>

<em>The father is 36 and a half years old.</em>

Hope this helps!

How to set the answer up
Korolek [52]

Let s and g represents the numbers of suits and gowns produced.

The number of zippers used is 2s+g.

The number of buttons used is 5s+8g.

In order to use all of the available zippers and buttons, we must have ...

  • 2s + g = 171
  • 5s + 8g = 576

Cramer's rule tells you the solution to the system

  • ax +by = c
  • dx +ey = f

Is given by

  • x = (bf-ey)/(bd-ea)
  • y = (cd-fa)/(bd-ea)

Using this rule on the equations for zippers and buttons, we have

... s = (1·576 -8·171)/(1·5 -8·2) = -792/-11 = 72

... g = (171·5 -2·576)/-11 = -297/-11 = 27

72 suits and 27 gowns can be made from available zippers and buttons.

Help asap please ----------------
melomori [17]

Answer:

-1 Not in domain

0 In domain

1 In domain

Step-by-step explanation:

The domain for the square root function is all positive numbers including (0). The domain is the set of real numbers which when substituted into the function will produce a real result. While one can substitute a negative number into the square root function and get a result, however, the result will be imaginary. Therefore, the domain for the square root function is all positive numbers. It can simply be expressed with the following inequality:

x\geq0

Therefore, one can state the following about the given numbers. Evaluate if the number is greater than or equal to zero, if it is, then it is a part of the domain;

-1 => less than zero; Not in domain

0 => equal to zero; <em> </em>In domain

1  => greater than zero: In domain
