Nikolay [14]3 years ago
6 0

Step-by-step explanation:

<u>Dimensions of the box, considering the base is a square:</u>

  • Length = w
  • Width = w
  • Height = h

(a)

The height is 9 inches greater than the width:

  • h = w  + 9

(b)

<u>Express the width in terms of height:</u>

  • w = h - 9

<u>Volume of the box:</u>

  • V = base * height
  • V = w²h
  • V = (h - 9)²h

Which is the correct label of parallel lines?
Sladkaya [172]

Answer: Parallel lines are marked with "feathers". Notice how they appear assets: the lines with one feather are parallels, and the lines with two feathers are parallel. A "box" at the point of intersection indicates the lines are perpendicular.

I found this on the web, maybe it will help you. Sorry if you still don't understand.

The number of games, g, to be played with n teams can be written by the following equation: g=n^2-n if there are to be 132 games
Tema [17]
The equation that describes the relation between the number of games (g) and the number of teams (n) is given as follows:
g = n^2 - n

Now, we are given that the number of games is 132. This means that g=132. To know the number of teams, substitute with the given g in the given equation as follows:
g = n^2 - n
132 = n^2 - n
n^2 - n - 132 = 0 .......> factorize this expression
(n-12)(n-11) = 0
This means that:
either n = 12 teams
Or n = -11 teams (this solution is rejected as the number of teams cannot be negative)

Therefore, based on the above calculations, if the number of games is 132, then, the number of teams is 12

spin [16.1K]

Answer:

Step-by-step explanation:

1) Find the Mean of all the numbers.

3+4+5+7+10+12+15=56

56/7=8 mean is 8

Now We Calculate Standard Deviation:

S=\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}

You take each number from the problem i.e 3,4,5...

and then you subtract the mean from it and then square it.

S=\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}

S=\sqrt{25+16+9+1+4+16+49}

S=\sqrt{120}

S=\sqrt{120}/7

7 is the amount of data units given in the problem.

120/7=17.1428571429

\sqrt{17.1428571429} =4.1403933560541
