What is the average 27, 12, 31, 19, 23, 11, 17
valentinak56 [21]

So to find average, we add up the values, and divide it by how many values there are in total.

27 + 12 + 31 + 19 + 23 + 11 + 17 = 140.

There are 7 numbers. Which means we divide 140 by 7.

140 / 7 = 20 is the average.

Also, if you notice, most of the numbers "kind of" circulate around 20.

• Packaging of a product can cost a lot of money. Can you design
podryga [215]

The best arrangement can be

  • 3 rows and 4balls each row

So

  • Length of one row=1.8(4)=7.2cm
  • Width=1.8(3)=5.4cm
  • Height=1.8(2)=3.6cm

So

TSA

  • 2(LB+BH+LH)
  • 2(5.4(7.2)+(7.2)(3.6)+3.6(5.4))
  • 2(84.24)
  • 168.48cm²

Total cost

  • 168.48(0.01)
  • 1.685€

Megan has $50 and saves $5.50 each week. Conner has $18.50 and saves $7.75 each week. After how many weeks will Megan and conner
QveST [7]

After 14 weeks, both Megan and Conner will have saved the same amount.

Step-by-step explanation:

Amount Megan have = $50

Amount saved each week = $5.50

Amount Conner have = $18.50

Amount saved each week = $7.75

Let,

x be the number of weeks.

According to given statement;

M(x) = 50+5.50x    Eqn 1

C(x) = 18.50+7.75x   Eqn 2

For amount to be same;

Eqn 1 = Eqn 2

50+5.50x=18.50+7.75x\\50-18.50=7.75x-5.50x\\31.50=2.25x\\2.25x=31.50\\

Dividing both sides by 2.25

\frac{2.25x}{2.25}=\frac{31.50}{2.25}\\x=14

After 14 weeks, both Megan and Conner will have saved the same amount.
