or
y^3-4y^2+7y-6=y^3-4y^2+4y+3y-6=
y(y^2-4y+4)+3(y-2)=
y(y-2)^2+3(y-2)=(y-2)[y(y-2)+3]=(y-2)(y^2-2y+3)
(y^3-4y^2+7y-6)(y-2)=(y-2)^2(y^2-2y+3)
Using it's concept, it is found that there is a 0.152 = 15.2% probability that they are both Democrats.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Two voters are selected, each with 39% probability of being Democrats, hence the probability of both being Democrats is given by:
p = (0.39)² = 0.152.
0.152 = 15.2% probability that they are both Democrats.

Answer:
Step-by-step explanation:
the shape is a trpizoid with height y
A=(a+b)/2 *h (a=2x=4cm, h=y=4cm, b=2z=12 cm
A=(4+12)/2 * 4
Area=16/2 *4=8*4= 32 cm²
Answer:
The graph that has the points (2,4) and (4,8) should be the answer.
Step-by-step explanation:
This is the answer because if you see the ratio 2:4, that means that for every 2 offense cards there are 4 defense cards. As you continue to go up it would be (4,8), (6,12), (8,16), and so forth.
