(2x-10)+(3x-10)=90
(2x+3x)+(-10-10)=90
(5x)+(-20)=90
5x=110
X=22
The first is 34, the second is 56.

He list shows the growth in centimeters of 12 plants during one week. 6, 7, 7, 8, 8, 8, 9, 9, 10, 11, 11, 14 Which box plot best
kumpel [21]

Answer:

Step-by-step explanation:

Hello!

You have the growth of 12 plants over a week (cm)

To construct a box plot you have to identify the 1st, 2nd, and 3rd Quartiles for the box and the maximum and minimum values for the whiskers.

Box

1st Quartile (Q₁)

Is the value of the data set that separates the bottom 25% from the top 75%. First, you need to calculate its position:

PosQ₁= n/4= 12/4= 3

So the first quartile is the third value.

6, 7, 7, 8, 8, 8, 9, 9, 10, 11, 11, 14

Q₁= 7

2nd Quartile/ Median (Q₂/Me)

PosMe= 12/2= 6

The second quartile in the 6th value.

6, 7, 7, 8, 8, 8, 9, 9, 10, 11, 11, 14

Q₂=Me= 8

3rd Quartile (Q₃)

PosQ₃= n*(3/4)= 12*(3/4)= 9

The third quartile is the 9th value.

6, 7, 7, 8, 8, 8, 9, 9, 10, 11, 11, 14

Q₃= 10

The left whisker extends from the Q₁ to the minimum value.

The right whisker extends from the Q₃ to the maximum value.

Min= 6

Max= 14

'------|     |      |-------'

6     7    8    10    14

The box plot that best displays a summary of the data, is C.

I hope this helps!

Hiw do i completely factor 5x^2+36x+7=0
Cerrena [4.2K]
There is a method I use called the x method, I can’t show it to you but I will do my best to explain it
Basically, the factors of 5 and 7 must equal 36, so it’s kind of like cross multiplying
5 X 1
1 7
Five times seven equals 35
1 Times 1 equals 1
35 + 1 = 36
This is the answer:
(5x+1) (x+7)

Use the Cosine Rule

q^2 = 20^2 + 30^2 - 2^20*30 cos 15

       =  140.89

so q = sqrt 140.89 =  11.9 (answer)
