Answer:
Here is your answer with solutions.
Answer:
Graph D > Graph A > Graph C > Graph B
Step-by-step explanation:
The closer the data points are to each other along the line of best fit, the greater the value of their correlation coefficient, and vice versa.
Therefore, the graphs can be arranged in descending other (from the highest to the lowest) based on the values of their correlation coefficients as follows:
Graph D > Graph A > Graph C > Graph B
<u>Answer:</u>
○ 
<u>Step-by-step explanation:</u>
Given the equation:
,
to solve for
, we have to rearrange the equation to make
its subject.

⇒
[expand brackets]
⇒ 
⇒
[add
to both sides]
⇒ 
⇒
[subtract 96 from both sides]
⇒ 
⇒
[divide both sides by 20]
⇒ 
Answer:
x = 1/2; y = 1/3
Step-by-step explanation:
2x + 3y = 2 Eq. 1
-6x + 12y = 1 Eq. 2
Eq. 1
2x + 3y = 2
2x = -3y + 2
x = -3/2 y + 1
Eq. 2
-6x + 12y = 1
De Eq. 1 sabemos que x = -3/2 y + 1
-6x + 12y = 1
-6(-3/2 y + 1) + 12y = 1
9y - 6 + 12y = 1
21y - 6 = 1
21y = 7
y = 7/21
y = 1/3
Eq. 1
2x + 3y = 2
2x + 3(1/3) = 2
2x + 1 = 2
2x = 1
x = 1/2
Respuesta: x = 1/2; y = 1/3
The picture in the attached figure
let
x--------> men voters
y-------> women voters
we know that
y=x+2800------> y-x=2800------> equation 1
step 1find the percentage of women and men voters
in the graph
central angle by men voters=130°
central angle by women voters=(360°-130°)-------> 230°
by using proportion
men voters
%
women voters
%
remember equation 1
y-x=2800
so
F-M=63.89%-36.11%----> 27.78%
if 27.78% correspond to 2800 voters
100%---------------------->T
T=100*2800/27.78-------> T=10,079.19 voters
the answer isabout 10,079 voters
