To know how many correspond to each tray if we divide the total cookies equally, we need to make a division of the total cookies divided by the amount of trays, that is:
567 cookies / 7 trays = 567/7
= 81
therefore, there will be 81 cookies in each tray

FinnZ [79.3K]

Answer:

This is called a sample.

In statistics, we take a random 'sample' of people so that we can estimate values for the entire population!

So, say for example you want to find out what percent of students in your school are girls. You take a sample, like this again, of 30 students, and 3/10 are girls, then you can apply it to the rest of the population.

Hope this helps!

P.S. Stay Safe!

A square tabletop has an area of
tiny-mole [99]

s = 3x - 15 is the required expression for perimeter of table top

Perimeter of square tabletop is 240 cm

<em><u>Solution:</u></em>

A square tabletop has an area given as:

(9x^2 - 90x+225) cm^2

The dimensions  of the tabletop have the form cx - di  ,where cand d are whole numbers

To find perimeter of tabletop when x = 25 centimeters

Let us first find the length of each side of square

<em><u>Given area is:</u></em>

area = (9x^2 - 90x+225)

We know that,

area = (side)^2 = s^2

Therefore,

s^2 = (9x^2 - 90x+225)\\\\s^2 = (3x - 15)(3x - 15)\\\\s^2 = (3x - 15)^2

Taking square root on both sides,

s = 3x - 15

The above expression is the required expression for perimeter of table top

<em><u>To find perimeter when x = 25 centimeter</u></em>

<em><u>The perimeter of square is given as:</u></em>

perimeter = 4s

perimeter = 4(3x - 15)

Substitute x = 25

perimeter = 4(3(25) - 15)

perimeter = 4(60) = 240

Therefore perimeter of square tabletop is 240 cm

Write a system of equations with a solution (4,–3)
Gennadij [26K]
<span>1.       </span><span>So we have the system of equation. (4, -3)
let’s create another system of equation.
Let a = 4
and Let b = -3
First equation
=> Let’s pick any numbers to be used. Let’s have number 5
=> 5a + 5b
=> 5 (4) + 5 (-3)
=> 20 + (-15)
negative and positive is equals to negative
=> 20 – 15
=> 5 (this the first value of our equation, let this be the value of X)

Second
=> Pick another number, Let’s have 6
=> 6a + 6b
=> 6 (4) + 6 (-3)
=> 24 + (-18)
=> 24 – 18
=> 6 (this is the value of our second equation, let this value be Y)

Now, we have (A, B) = (4, -3) and (X, Y) = (5,6)</span>
