Tamiku [17]
There were 3  friends. Each of them bought 6 packs of candy. Each pack had 18 pieces of candy. How much candy did they have in total? . 

3 × 6 = 18

18 × 18 = 324

SO, they had 324 pieces of candy in total.

Hope I helped:P

HURRY PLEASE <br><br> What is the solution of the system 4x+3y=6 2x+2y=5
jolli1 [7]
The first given equation is:
4x + 3y = 6
which can be rewritten as:
2(2x) + 3y = 6 .............> equation I

The second given equation is:
2x + 2y = 5
which can be rewritten as:
2x = 5 - 2y ........> equation II

Substitute with equation II in equation I to get the value of y as follows:
2(5-2y) + 3y = 6
10 - 4y + 3y = 6
-y = 6-10 = -4
y = 4

Substitute with the y in equation II to get x as follows:
2x = 5 - 2y
2x = 5 - 2(4)
2x = 5 - 8 = -3
x = -3/2

From the above calculations:
x = -3/2
y = 4

Which best describes the shape of this distribution?
Karolina [17]
Answer: Choice E) bimodal skewed

The majority of the data is towards the left side. The right outliers are skewing the mean to be pulled larger than it should be. This is why median < mean, so it's better to use the median as the measure of center. There are 2 modes here. They are the values 4 and 8 since we have these values occur the most (4 times each). That's where the term "bimodal" comes in.

Hi, can anyone show me how to do this problem? 100 points for this.<br> Thanks in advance
algol [13]

Answer:

z^2 + (-1 + 5·i)·z + 14 - 7·i = 0

(1 + 2·i)^2 + (-1 + 5·i)·(1 + 2·i) + 14 - 7·i = 0

(1 + 4·i - 4) + (-1 - 2·i + 5·i - 10) + 14 - 7·i = 0

0 = 0 --> true

z^2 + (-1 + 5·i)·z + 14 - 7·i = 0

(1 - 2·i)^2 + (-1 + 5·i)·(1 - 2·i) + 14 - 7·i = 0

(1 - 4·i - 4) + (-1 + 2·i + 5·i + 10) + 14 - 7·i = 0

20 - 4·i = 0 --> false
