Find the mean of the following number set: 89, 76, 85, 76, 77, 84

klio [65]

Answer:

81.167~

Step-by-step explanation:

You can find the mean (or average) of a set of numbers by adding them together and dividing the sum by the amount of values there are.

In this case, there are 6 values.

The total sum of the six values is 487.

To receive the mean, divide 487 by 6.

An open box is to be constructed so that the length of the base is 3 times larger than the width of the base. If the cost to con

natta225 [31]

Answer:

Step-by-step explanation:

Let assume that the volume = 88 cubic feet

Then:

$L = 3w --- (1)volume = l \times w \times h \\ \\ 88 = (3w) \times w \times h \\ \\ 3w^2 h= 88 \\ \\ h = \dfrac{88}{3w^2}--- (2) \\ \\$

The construction cost now is:

$C = 4(l \times w) + 2 ( w \times h) + 2(l \times h) \\ \\ C = 4(3w^2) + 2(w \times \dfrac{88}{3w^2}) + 2(3w \times \dfrac{88}{3w^2}) \\\\ C = 12w^2 + \dfrac{176}{3w} + \dfrac{176}{w}$

Now, to determine the minimum cost:

$\dfrac{dC}{dw}= 0 \\ \\ \implies 24 w - \dfrac{176}{3w^2}- \dfrac{176}{w^2}=0 \\ \\ 24 w ^3 = \dfrac{176}{w^2}(\dfrac{1}{3}+1) \\ \\ 24 w ^3 = \dfrac{176(4)}{3} \\ \\ w^3 = \dfrac{88}{3(3)}$

$w = \dfrac{88}{3(3)}^{1/3} \ feet$

Now;

$length = 3 ( \dfrac{88}{3(3)})^{1/3} \ feet$

$height = ( 88})^{1/3} (3)^{1/3} \ feet$

How many more games will it take until tom and will have scored the same number of points

erma4kov [3.2K]

Answer:

<em>Both players will need to play 7 more games to have the same score.</em>

Step-by-step explanation:

Will makes 18 points per game and Tom makes 21 points per game. Will has a total of 483 points and Tom has 462 points.

We have to calculate the number of games Tom and Will need to play for them to have the same number of points. Since Tom makes more points per game, we're sure it will eventually happen.

Let's call x to the number of games that both players will play. Will will have a number of points equal to:

W = 483 + 18x

And Tom will have:

T = 462 + 21x

For both number of games to be equal, the equation to solve is:

483 + 18x= 462 + 21x

Move 18x to the right side and 462 to the left side:

483 - 462 = 21x - 18x

Operating:

21 = 3x

x = 21 / 3 = 7

Thus, both players will need to play 7 more games to have the same score.
