Answer:

x_{min} = 75\,camisas

Step-by-step explanation:

El número mínimo de camisas a vender es igual al costo de alquiler del local dividido por la diferencia entre los valores de venta y compra de cada camisa. (The minimum amount of shirts to be sold is equal to the rental cost of the retail space divided by the difference between sell and purchase cost per shirt):

x_{min} = \frac{\$ 150}{\$ 5 - \$ 3}

x_{min} = 75\,camisas

Miguelito debe vender un mínimo de 75 camisas para obtener ganacias. (Miguelito must sell a minimum of 75 shirts to make a profit.)

If x = 1, y = 7, and z = 15, determine a number that when added to x, y, and z yields
almond37 [142]

You're looking for a number <em>w</em> such that the numbers

{1 + <em>w</em>, 7 + <em>w</em>, 15 + <em>w</em>}

form a geometric sequence, which in turn means there is a constant <em>r</em> for which

7 + <em>w</em> = <em>r</em> (1 + <em>w</em>)

15 + <em>w</em> = <em>r</em> (7 + <em>w</em>)

Solving for <em>r</em>, we get

<em>r</em> = (7 + <em>w</em>) / (1 + <em>w</em>) = (15 + <em>w</em>) / (7 + <em>w</em>)

Solve this for <em>w</em> :

(7 + <em>w</em>)² = (15 + <em>w</em>) (1 + <em>w</em>)

49 + 14<em>w</em> + <em>w</em> ² = 15 + 16<em>w</em> + <em>w</em> ²

2<em>w</em> = 34

<em>w</em> = 17

Then the three terms in the sequence are

{18, 24, 32}

and indeed we have 24/18 = 4/3 and 32/24 = 4/3.

If you know the area of a rectangle can you predict its perimeter? Explain
Anuta_ua [19.1K]

No.  The area doesn't tell you the dimensions, and you need
the dimensions if you want the perimeter.

If you know the area, you only know the <em><u>product</u></em> of the length and width,
but you don't know what either of them is.

In fact, you can draw an infinite number of <em><u>different</u></em> rectangles
that all have the <em>same</em> area but <em><u>different</u></em> perimeters.

Here.  Look at this.
I tell you that a rectangle's area is 256.  What is its perimeter ?

-- If the rectangle is 16 by 16, then its perimeter is 64 .
-- If the rectangle is 8 by 32, then its perimeter is 80 .
-- If the rectangle is 4 by 64, then its perimeter is 136 .
-- If the rectangle is 2 by 128, then its perimeter is 260 .
-- If the rectangle is 1 by 256, then its perimeter is 514 .
-- If the rectangle is 0.01 by 25,600 then its perimeter is 51,200.02

If the animal is in the woods on one observation, then it is four times as likely to be in the woods as the meadows on the next
kvv77 [185]
My solution to the problem is as follows:

<span>day 1: 1 
day 2: 0.6667 
day 3: 0.5111 
day 4: 0.4385 <-------
</span>
Therefore, <span>the probability that the animal is in the woods on fourth observation would be 0.4385.

I hope my answer has come to your help. God bless and have a nice day ahead!
